The observation field of Okayama local meteorological observatory was moved to the Tsushima Campus of Okayama University from the downtown area of Okayama City in March, 2015. Comparison between the air temperature records measured at meteorological agency station and the records at Tanjo Pond in Tsushima Campus, showed 0.56 ℃ drop in annual average before and after relocation. Moreover, comparison between the records of Okayama local meteorological observatory and that at the surrounding meteorological observing 9 stations showed 0.55 ℃ drop in annual average. Those results suggest that the relocation dropped annual average of air temperature by about 0.6 ℃. en-copyright= kn-copyright= en-aut-name=MiuraTakeshi en-aut-sei=Miura en-aut-mei=Takeshi kn-aut-name=三浦健志 kn-aut-sei=三浦 kn-aut-mei=健志 aut-affil-num=1 ORCID= en-aut-name=UedaYu en-aut-sei=Ueda en-aut-mei=Yu kn-aut-name=上田悠生 kn-aut-sei=上田 kn-aut-mei=悠生 aut-affil-num=2 ORCID= en-aut-name=MoritaHidenori en-aut-sei=Morita en-aut-mei=Hidenori kn-aut-name=守田秀則 kn-aut-sei=守田 kn-aut-mei=秀則 aut-affil-num=3 ORCID= en-aut-name=ChikamoriHidetaka en-aut-sei=Chikamori en-aut-mei=Hidetaka kn-aut-name=近森秀高 kn-aut-sei=近森 kn-aut-mei=秀高 aut-affil-num=4 ORCID= en-aut-name=KurokawaMasahiro en-aut-sei=Kurokawa en-aut-mei=Masahiro kn-aut-name=黒川正宏 kn-aut-sei=黒川 kn-aut-mei=正宏 aut-affil-num=5 ORCID= en-aut-name=NakashimaYoshitaka en-aut-sei=Nakashima en-aut-mei=Yoshitaka kn-aut-name=中嶋佳貴 kn-aut-sei=中嶋 kn-aut-mei=佳貴 aut-affil-num=6 ORCID= en-aut-name=OkiYoko en-aut-sei=Oki en-aut-mei=Yoko kn-aut-name=沖陽子 kn-aut-sei=沖 kn-aut-mei=陽子 aut-affil-num=7 ORCID= affil-num=1 en-affil=Graduate School of Environmental and life Science, Okayama University kn-affil=岡山大学大学院環境生命科学研究科 affil-num=2 en-affil=Graduate School of Environmental and life Science, Okayama University kn-affil=岡山大学大学院環境生命科学研究科 affil-num=3 en-affil=Graduate School of Environmental and life Science, Okayama University kn-affil=岡山大学大学院環境生命科学研究科 affil-num=4 en-affil=Graduate School of Environmental and life Science, Okayama University kn-affil=岡山大学大学院環境生命科学研究科 affil-num=5 en-affil= kn-affil=岡山大学環境理工学部 affil-num=6 en-affil=Graduate School of Environmental and life Science, Okayama University kn-affil=岡山大学大学院環境生命科学研究科 affil-num=7 en-affil=Graduate School of Environmental and life Science, Okayama University kn-affil=岡山大学大学院環境生命科学研究科 en-keyword=Okayama Local Meteorological Observatory kn-keyword=Okayama Local Meteorological Observatory en-keyword=relocation kn-keyword=relocation en-keyword=drop in air temperature kn-keyword=drop in air temperature END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue= article-no= start-page=17 end-page=22 dt-received= dt-revised= dt-accepted= dt-pub-year=1991 dt-pub=199112 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Environment Protection around Kojima Lake kn-title=児島湖の環境保全問題 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=OkiYoko en-aut-sei=Oki en-aut-mei=Yoko kn-aut-name=沖陽子 kn-aut-sei=沖 kn-aut-mei=陽子 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学農学部 END start-ver=1.4 cd-journal=joma no-vol=32 cd-vols= no-issue= article-no= start-page=1 end-page=1 dt-received= dt-revised= dt-accepted= dt-pub-year=2010 dt-pub=201012 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=今､キャンパスで求められる環境マネジメントとは? en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=沖陽子 kn-aut-sei=沖 kn-aut-mei=陽子 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学環境管理センター END start-ver=1.4 cd-journal=joma no-vol=33 cd-vols= no-issue= article-no= start-page=35 end-page=36 dt-received= dt-revised= dt-accepted= dt-pub-year=2012 dt-pub=201202 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=サステイナブル・キャンパスを目指して en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=沖陽子 kn-aut-sei=沖 kn-aut-mei=陽子 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学環境管理センター END start-ver=1.4 cd-journal=joma no-vol=87 cd-vols= no-issue=1 article-no= start-page=155 end-page=161 dt-received= dt-revised= dt-accepted= dt-pub-year=1998 dt-pub=199802 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Differences in Salt Tolerance within Strains of Cynodon dactylon kn-title=ギョウギシバの耐塩性における系統間差異 en-subtitle= kn-subtitle= en-abstract=近年、乾燥地域、半乾燥地域、乾燥半湿潤地域における気候上の変動や人間活動を含む様々な要素に起因する土地の劣化が進んでいる。その劣化の中で、灌漑農地の土壌の塩類化が大きな問題となっている。これは、灌漑が行われる際に、過剰な灌漑や水路からの漏水等のために地下水位の上昇が起こったり、塩類濃度の高い地下水を用いることにより、水分が蒸発した後に水に含まれていた塩類が表層面に集積し、塩化によって農地が荒廃、劣化することである。とくに土壌の浸透圧を高め、植物の吸収わ妨げたり、植物体内のイオンバランスを崩すなど生理作用を阻害する塩化ナトリウム(NaCl)などの中性のナトリウムが問題であるといわれている。このような塩類集積土壌は世界の陸地面積の約10％、100カ国以上に及んでおり、早急な修復が望まれている。解決策の一つとして、生物生産性を高める土壌に改善するために、まず、耐塩性の高い植物好塩性の植物を緑化資材として導入することが考えられる。筆者は、タイ東北部の塩類集積土壌の植生調査をじっしするきかいがあり、ギョウギシバが自生しているのを確認した。また、国内においても海岸地帯に広く自生しているので、塩類集積土壌に自生する有用資源植物の候補種として選定した。ギョウギシバ(Cynodon dactylon (L.) Pers.)は寒帯を除く、ほとんど全世界の分布するイネ科多年生植物で、日本でも各地の路傍、原野、海浜に広く生育する。また、世界の畑地の強害草であると共に、飼料作物や芝生用にも活用される植物である。そこで、ギョウギシバにNaCl処理を行い耐塩性の程度を調査した結果、Cl濃度で5000ppm以上では乾物生産に影響が現れるが、比較的耐塩性の高い植物であることが把握された。従って、本実験では、海岸付近や塩類集積地などの影響のある土壌に自生していたギョウギシバの系統と、路傍など塩分の影響のない土壌に自生していた系統を供試し、NaCl処理を行うことにより、塩分濃度が生育と外部形態に及ぼす影響、及び、耐塩性の系統間差異を検討した。さらに、これらの結果を踏まえて塩類集積地や海浜における緑化被覆植物として活用する可能性を探った。 kn-abstract=Nine strains of Cynodon dactylon grass were collected from various habitats as the seaside, the saline soil areas and the roadside. These strains were grown in sand culture under greenhouse at various NaCl treatments, and their growth, morphological variation, mineral contents and rooting were determined. The growth of most strains was increased by Cl concentrations of 1,000 ppm to 3,000 ppm, and addition of NaCl up to 5,000 ppm of Cl concentrations did not affect their growth. Furthermore all strains survived relatively well even when grown with Cl concentrations of 10,000 ppm. With increasing Cl concentrations, Na content in their tissues increased. Especially some strains which were collected from saline areas, had higher Na content in their tissues than those of other strains. It was also found that Cynodon dactylon may possess one mechanism for salt tolerance, which be related to restriction of Na translocation from root to top. Morphological characters of all strains at various NaCl treatments varied widely, and a relation between morphological variation and yield variation was found. In contrast, NaCl treatments significantly affected the rooting and the root growth of Cynodon dactylon. en-copyright= kn-copyright= en-aut-name=OKiYoko en-aut-sei=OKi en-aut-mei=Yoko kn-aut-name=沖陽子 kn-aut-sei=沖 kn-aut-mei=陽子 aut-affil-num=1 ORCID= en-aut-name=UtsugiTomo en-aut-sei=Utsugi en-aut-mei=Tomo kn-aut-name=宇津木友 kn-aut-sei=宇津木 kn-aut-mei=友 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 en-keyword=Cynodon dactylon kn-keyword=Cynodon dactylon en-keyword=salt tolerance kn-keyword=salt tolerance en-keyword=strains kn-keyword=strains en-keyword=NaCl treatments kn-keyword=NaCl treatments en-keyword=rooting kn-keyword=rooting END start-ver=1.4 cd-journal=joma no-vol=7 cd-vols= no-issue=1 article-no= start-page=91 end-page=98 dt-received= dt-revised= dt-accepted= dt-pub-year=2002 dt-pub=20020322 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The separate or the combined effect of hypoxia and salinity on growth and ionic relations of four wheat varieties en-subtitle= kn-subtitle= en-abstract= kn-abstract=To evaluate hypoxic-salinity tolerance in wheat varieties, three Japanese varieties (Nourin-61, Chikugo Izumi and Shirasagi Komugi, relatively salt tolerant) and one Pakistani variety (Blue Silver, relatively salt sensitive) were grown under control, hypoxia, saline and hypoxic-saline conditions. The results suggested that relatively hypoxia and salt tolerant variety Nourin-61 was capable of producing the highest relative shoot yield under combined stress conditions. On the other hand, relatively sensitive variety to both hypoxia and salinity conditions, could not withstand harmful effects of combined stress. A more close correlation of plant growth characters between salinity and hypoxic-salinity than hypoxia and hypoxic-salinity indicated that varieties with higher salt tolerance would suffer less than varieties with higher hypoxia tolerance under combined stress conditions. And the balance of Na/K ratio in shoot tissues seems to be the major evaluation factor as the tolerant variety when salinity and hypoxia stress occur together. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=KambohMaqsood Ahmed kn-aut-sei=Kamboh kn-aut-mei=Maqsood Ahmed aut-affil-num=1 ORCID= en-aut-name=OkiYoko en-aut-sei=Oki en-aut-mei=Yoko kn-aut-name=沖陽子 kn-aut-sei=沖 kn-aut-mei=陽子 aut-affil-num=2 ORCID= en-aut-name=AdachiTadashi en-aut-sei=Adachi en-aut-mei=Tadashi kn-aut-name=足立忠司 kn-aut-sei=足立 kn-aut-mei=忠司 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 en-keyword=hypoxia kn-keyword=hypoxia en-keyword=growth and ionic composition kn-keyword=growth and ionic composition en-keyword=salinity kn-keyword=salinity en-keyword=salt tolerance kn-keyword=salt tolerance en-keyword=wheat varieties kn-keyword=wheat varieties END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=1 article-no= start-page=111 end-page=119 dt-received= dt-revised= dt-accepted= dt-pub-year=2008 dt-pub=200803 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Phosphorus and Biomass Distribution, and P-efficiency by Diverse Brassica Cultivars Exposed to Adequate and P-stress Environment en-subtitle= kn-subtitle= en-abstract= kn-abstract=To acclimate under orthophosphate (Pi) starved environment, plant species and cultivars display an elegant myriad of Pi-adaptive and rescue responses via reprioritizing internal Pi use and maximizing external Pi acquisition by reprogramming metabolism and restructuring root system architecture.Exploitation of considerable genetic diversity both between and within crop species and harnessing of these genetic variations can lead us to develop smart plants with improved P-acquisition, growth and yield under P-deprivation. To elucidate the effect of P-stress on plant growth, and P-efficiency under Pstarvation, 14 diverse Brassica cultivars were grown hydroponically in a climatically controlled chamber using sufficient (200 and 400 μM) and stress (10 and 20 μM) P-levels using ammonium phosphate (NH4H2PO4) as a P source. Cultivars showed differential growth behaviour in terms of biomass accumulation (shoot and root dry matter partitioning), percent distribution of Pi-concentration ([P]) and P-contents in plant parts (roots and shoots), and P-efficiency ratio (% PER)(relative shoot growth) indicating considerable genetic diversity among the tested Brassica cultivars. PER and the proportional increases in shoot dry matter (SDM) accumulation (SDMmax/SDMmin) in response to the P levels assisted in categorizing the cultivars into efficient and inefficient utilizers of the absorbed P from an ambient environment. Cultivars were classified into efficient responsive (ER), efficient non-responsive (ENR), non-efficient responsive (NER) and non-efficient non-responsive (NENR) by plotting ordination plots between PER and SDMmax/SDMmin under P-stress environment. Differential PER values at stress P levels corresponds to high P levels suggest that P efficiency mechanisms can be different from one cultivar to another within a give plant species and cultivars exhibiting high PER values are better choice to thrive under P-starvation. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=AkhtarM.Shahbaz kn-aut-sei=Akhtar kn-aut-mei=M.Shahbaz aut-affil-num=1 ORCID= en-aut-name=OkiYoko en-aut-sei=Oki en-aut-mei=Yoko kn-aut-name=沖陽子 kn-aut-sei=沖 kn-aut-mei=陽子 aut-affil-num=2 ORCID= en-aut-name=AdachiTadashi en-aut-sei=Adachi en-aut-mei=Tadashi kn-aut-name=足立忠司 kn-aut-sei=足立 kn-aut-mei=忠司 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=University of Agriculture affil-num=2 en-affil= kn-affil=Okayama University affil-num=3 en-affil= kn-affil=Okayama University en-keyword=Brassica cultivars kn-keyword=Brassica cultivars en-keyword=biomass and P-distribution kn-keyword=biomass and P-distribution en-keyword=P-contents kn-keyword=P-contents en-keyword=P-efficiency ratio kn-keyword=P-efficiency ratio END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=1 article-no= start-page=497 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20221228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Interspecific Variability in Growth Characteristics and Phytoremediation of Cu by Free-Floating Azolla Macrophytes en-subtitle= kn-subtitle= en-abstract= kn-abstract=The phytoremediation potential of aquatic plants, particularly for Cu, is scarcely reported in the pertinent literature. In this regard, differential growth behavior and phytoaccumulation ability of three free-floating Azolla species (A. japonica, A. pinnata, and A. hybrid) were evaluated in a climatically controlled (a temperature of 25/20 degrees C, light/dark 16/8 h, a light intensity of 60 mu mol m(-2) s(-1), and a relative humidity of 65%) microcosm study. Azolla plants were exposed to solutions having three Cu concentrations (0, 3, and 6 mg L-1) under two incubation periods (4 and 8 days). Different Cu treatments significantly reduced Azolla biomass during both incubation periods and A. pinnata was the most sensitive species. Azolla plants grown in aqueous solutions showed substantial variations in Cu removal capacity. Higher bioconcentration values displayed by Azolla plants indicated that these plants can be deployed as potential plants for Cu removal from Cu contaminated water. Nevertheless, the plants exposed to higher Cu concentrations displayed color changes and root detachment due to Cu phytotoxic effects which may also ultimately lead to plant death. Significant correlations between Cu removed from the aqueous solutions and Cu contents of plant biomass indicated that Cu phytoremediation by Azolla plants was due to the phytoaccumulation mechanism because the removed Cu from aqueous solutions was accumulated in plant biomass. Introduced Azolla species, i.e., A. hybrid, displayed comparable Cu removal efficiency with naturally grown Azolla species, i.e., A. japonica and A. pinnata. Tested Azolla species proved to be suitable candidates to remediate Cu contaminated water and can be deployed for phytoremediation. en-copyright= kn-copyright= en-aut-name=AkhtarMuhammad Shahbaz en-aut-sei=Akhtar en-aut-mei=Muhammad Shahbaz kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AslamSohaib en-aut-sei=Aslam en-aut-mei=Sohaib kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=DittaAllah en-aut-sei=Ditta en-aut-mei=Allah kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AlbalawiBedur Faleh A. en-aut-sei=Albalawi en-aut-mei=Bedur Faleh A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkiYoko en-aut-sei=Oki en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakashimaYoshitaka en-aut-sei=Nakashima en-aut-mei=Yoshitaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Environmental Sciences, Forman Christian College University kn-affil= affil-num=2 en-affil=Department of Environmental Sciences, Forman Christian College University kn-affil= affil-num=3 en-affil=Department of Environmental Sciences, Shaheed Benazir Bhutto University kn-affil= affil-num=4 en-affil=Department of Biology, University of Tabuk kn-affil= affil-num=5 en-affil=Department of Environmental Management Engineering, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=6 en-affil=Department of Environmental Management Engineering, Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=Azolla biomass kn-keyword=Azolla biomass en-keyword=bioconcentration factor kn-keyword=bioconcentration factor en-keyword=Cu removal efficiency kn-keyword=Cu removal efficiency en-keyword=Cu toxicity kn-keyword=Cu toxicity en-keyword=translocation factor kn-keyword=translocation factor END start-ver=1.4 cd-journal=joma no-vol=4 cd-vols= no-issue=1 article-no= start-page=131 end-page=145 dt-received= dt-revised= dt-accepted= dt-pub-year=1999 dt-pub=19990226 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Growth, Yield and Mineral Composition of Three Rice Varieties Cultivated under Salt-Affected Conditions en-subtitle= kn-subtitle= en-abstract= kn-abstract=A pot experiment was conducted to study the relative performance of IR 6,KS 282 and IR 10198-66-2 rice varieties cultivated under salt-affected conditions at EC of 6.0,9.0 12.0 dS m(-1) in a sandy clay loam soil havig ECe of 1.6 dS m(-1) treated as control. Six seedlings of 39-day old transplaned to each pot having 12 kg soil. The fertilizer as nitrophos and potassium sulphate at the rate of 57.0, 25.0 and 50.0 mg N,P and K kg(-1) soil respectively was applied at the time of transplanting while zinc sulphate at the rate of 5 mg Zn kg(-1) soil and 43.0 mg N kg(-1) of soil as additional dose were applied 19 and 30 days after transplanting respectively. Normal plant protection measures like number of tillers, panicles, paddy grains, filled and unifilled grains, yield per plant and sterility were recorded and shoot and straw samples were analysed for sodium, potassium, calcium and chloride contents. It was observed that growth and yield of all the varieties were reduced significantly with increasing soil salinity. Na/K and Na/Ca rations in shoot and straw increased significantly with increasing soil salinity. It was also observed that higher values of Na/K and Na/Ca rations in shoots affected growth parameters while higher values of these rations in straw affected yield components and grain yield. However, IR 6 having relatively lower values of Na/K and Na/Ca rations proved to be the most salt-tolerant rice among the three varieties studied. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=KambohMaqsood Ahmed kn-aut-sei=Kamboh kn-aut-mei=Maqsood Ahmed aut-affil-num=1 ORCID= en-aut-name=OkiYoko en-aut-sei=Oki en-aut-mei=Yoko kn-aut-name=沖陽子 kn-aut-sei=沖 kn-aut-mei=陽子 aut-affil-num=2 ORCID= en-aut-name=AdachiTadashi en-aut-sei=Adachi en-aut-mei=Tadashi kn-aut-name=足立忠司 kn-aut-sei=足立 kn-aut-mei=忠司 aut-affil-num=3 ORCID= en-aut-name=NariokaHajime en-aut-sei=Narioka en-aut-mei=Hajime kn-aut-name=成岡市 kn-aut-sei=成岡 kn-aut-mei=市 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 affil-num=4 en-affil= kn-affil=岡山大学 en-keyword=soil salinity kn-keyword=soil salinity en-keyword=growth and yield kn-keyword=growth and yield en-keyword=mineral compasition kn-keyword=mineral compasition en-keyword=rice varieties kn-keyword=rice varieties END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=1 article-no= start-page=99 end-page=106 dt-received= dt-revised= dt-accepted= dt-pub-year=2007 dt-pub=20070315 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=From Fate to Faith and Soil to Cell: Estimation of Phosphate (Pi) Uptake Rate, Pi-Uptake Kinetics and Relative Growth Rate are Important Parameters to Scavenge Pi by Brassica Cultivars under P-Starved Environment en-subtitle= kn-subtitle= en-abstract= kn-abstract=As a rule, ion uptake by plant cells and roots has features of saturation kinetics. This is in accordance with the assumption of control, as for example by the number of binding sites of ions (carriers, permeases), or the capacity of the proton efflux pumps, in the plasma membrane and tonoplast. Solute transport across membranes is carrier mediated transport. Protein macromolecules integrated into the membrane matrix seems to be the carriers. The carrier-mediated process is subject to kinetics assumig that the number of carriers (binding sites) in the membranes is limited. Kinetics of ion transport through a membrane is considered equivalent to relationship between an enzyme and its substrate. To obtain plants of different P status, two genetically diverse Brassica cultivars (P-tolerant 'Con-1' and P-sensitive 'Gold Rush') were grown for several weeks in nutrient solution culture media. P-uptake kinetics of the roots with intact plants in short-term experiments by monitoring P depletion in culture media revealed that P-tolerant 'Con-1' cultivar had favorable characteristics for P-uptake because of high I(max) or V(max) and low K(m) or 1/2 I(max) value than P-sensitive 'Gold Rush' cultivar. By plotting relative growth rate (RGR) and internal P-concentration (PNC) among P-tolerant (group I; Brown Raya, Con-1, Rainbow, Dunkled and Peela Raya) and P-sensitive (group II; Toria, Sultan Raya, B.S.A, Toria Selection and Gold Rush) cultivars revealed that group I cultivars showed large metabolic fraction and small structural fraction than group II cultivars which provided basis for P-stress tolerance. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=AkhtarM.

The average sand content of the burnt (soil around brick kilns) soil profiles was increased by 245%, while 39 and 36% decreased the silt and clay contents. Soil organic carbon (Corg) in the unburnt soils (0-20 cm) at different agro-ecological zones in the eastern region of Bangladesh ranged from 0.8 and 1.4%, whereas the content of microbial biomass carbon (Cmic) in the studied unburnt soils ranged between 5 and 7% of the total Corg, suggesting that the microbial biomass releasing considerable amounts of carbon in soil while burning of the soils drastically reduced this contribution to about 1%. The values of soil Cmic in the unburnt soils were approximately 2 to 6 times higher in the topsoils than the subsoils (20-60 cm). Variable rainfall, temperature and soil fertility had an overriding influence, which was reflected by the average minimum (276 μg g(-1)) and maximum (439) amounts of soil Cmic in Moulvibazar and Cox' Bazar sites. The Cmic decreased upon soil burning by 92% of its original average value (346 μg g(-1)) in the soil profile of up to 100 cm. Burning of topsoils strikingly increased the Corg/Cmic ratio by about 6 to 9 times, while reduced the C/N ratio by about 1.5 to 2.5 times. The average loss of Corg, available and total N due to burning of the soils were 66, 72 and 44% (increase over average content of unburnt soil: IOAC), respectively, which suggests that the burning of the soils offset the essential roles of soil microorganisms, reduced soil fertility and soil microbial contribution. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=KhanMd.

The wheat varieties were grown in nutrient solution and subjected to 0 (control), 25,75 and 125 mM NaCl salinity levels for 7 days. Although the shoot growth was reduced while Na contents were increased progressively with increasing salinity in all varieties, the varieties were quite different in their response. Salt tolerant va rieties maintained less reduction in their root and shoot growth and better water relations in their shoots than salt sensitive varieties under saline conditions. The wheat varieties were quite different in their Na exclusion capacity. Poor growth in salt sensitive varieties might be due to higher accumulation of Na in their shoots resulting from low Na exclusion capacity of roots, higher Na transport to shoot and/or inferior compartmentation capability. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=KambohMaqsood Ahmed kn-aut-sei=Kamboh kn-aut-mei=Maqsood Ahmed aut-affil-num=1 ORCID= en-aut-name=OkiYoko en-aut-sei=Oki en-aut-mei=Yoko kn-aut-name=沖陽子 kn-aut-sei=沖 kn-aut-mei=陽子 aut-affil-num=2 ORCID= en-aut-name=AdachiTadashi en-aut-sei=Adachi en-aut-mei=Tadashi kn-aut-name=足立忠司 kn-aut-sei=足立 kn-aut-mei=忠司 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 en-keyword=growth and mineral composition kn-keyword=growth and mineral composition en-keyword=increasing salinity kn-keyword=increasing salinity en-keyword=Na exclusion capacity kn-keyword=Na exclusion capacity en-keyword=salt tolerance kn-keyword=salt tolerance en-keyword=wheat varieties kn-keyword=wheat varieties END start-ver=1.4 cd-journal=joma no-vol=6 cd-vols= no-issue=1 article-no= start-page=67 end-page=79 dt-received= dt-revised= dt-accepted= dt-pub-year=2001 dt-pub=20010228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Distribution of Mineral Ions in Root and Leaf Tissues and Their Role in Salt Tolerance of Wheat Varieties under Saline Conditions en-subtitle= kn-subtitle= en-abstract= kn-abstract=The distribution on Ca, K, Na and Cl in root and leaves was studied in salt tolerant variety (Chikugo Izumi) and salt sensitive variety (PB-81) of wheat under saline conditions. The plants grown in 5% Hoagland's nutrient solution were subjected to 100 mM NaCl salinity for one week before observation with scanning electron microscope and analysis of selected samples with X-ray microanalyzer. Root growth was not affected in salt tolerant variety but reduced significantly in salt sensitive variety. Shoot growth was reduced in both varieties but much higher in salt sensitive variety. Salinity increased accumulation of Na and Cl in all root cells including vascular cells in salt sensitive variety. Salt tolerant variety not only reduced uptake of Na and Cl under saline conditions but also restricted their accumulation in cortex maintaining vascular cells relatively free of these ions. Salt sensitive variety failed to block transport of Na and Cl from root to leaves leading to much accumulation of these ions in leaves under salinity sterss. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=KambohMaqsood Ahmed kn-aut-sei=Kamboh kn-aut-mei=Maqsood Ahmed aut-affil-num=1 ORCID= en-aut-name=OkiYoko en-aut-sei=Oki en-aut-mei=Yoko kn-aut-name=沖陽子 kn-aut-sei=沖 kn-aut-mei=陽子 aut-affil-num=2 ORCID= en-aut-name=AdachiTadashi en-aut-sei=Adachi en-aut-mei=Tadashi kn-aut-name=足立忠司 kn-aut-sei=足立 kn-aut-mei=忠司 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 en-keyword=Ion distribution kn-keyword=Ion distribution en-keyword=salinity kn-keyword=salinity en-keyword=salt tolerance kn-keyword=salt tolerance en-keyword=wheat varieties kn-keyword=wheat varieties en-keyword=X-ray microanalysis kn-keyword=X-ray microanalysis END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=1 article-no= start-page=77 end-page=81 dt-received= dt-revised= dt-accepted= dt-pub-year=2007 dt-pub=20070315 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Characterization and Screening of N(2)-fixing Microorganisms at Maturity Stage in Rhizosphere of Rice Grown in Brahmaputra Alluvium Soil of Bangladesh en-subtitle= kn-subtitle= en-abstract= kn-abstract=Studies on the existing non-symbiotic diazotrophic systems still are the most promising for better use of biological nitrogen fixation (BNF) in agriculture. The possibilities for the extension of nitrogen fixation to rice plants still speculative. The prospect of extension of N(2)-fixation to other plants was originally formulated to simulate the possibilities for the biological use of atmospheric nitrogen in order to overcome the ecological and economical problems of nitrogenous fertilizers. In view of this, the present study was conducted for the characterization and identification of N(2)-fixing bacterial strains at the maturity (110 days) stage in rhizosphere of rice (BR 10, Oryza sativa L.) grown in Brahmaputra Alluvium soil of Bangladesh. The soil is characterized as 'Inceptisol' order and 'Aquept' suborder. It was identified as 'Dhamrai series', had 'silt' texture, pH 6.0 and 6.8 C/N ratio. The present results of the microbial tests on the rice rhizosphere soil demonstrated that out of 401 isolates, only 94 were branded as nitrogen fixing organisms per gram of soil, which is about 23.4% of the total isolates. Based on the selection criteria, four individual strains were selected for identification. Biochemical tests were conducted for proper identification. They were identified as Closteridium spp., Klebsiella spp., Bacillus spp. and Azospirllum spp. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=KhanMd. H.

For effective selection, information on nature and magnitude of variation in population, association of character with dry matter yield and among themselves and the extent of environmental influence on the expression of these characters are necessary. The estimates of genetic parameters help in understanding the role of various plant traits in establishing the growth behavior of cultivars under a given set of environmental conditions. Genetic analysis leads us to a clear understanding of different morphological, physiological and genetic characters and also the type and extent of their contribution to dry matter yield. Six Brassica cultivars were grown in a P-deficient sandy loam soil for 49 days after sowing. Significant variations were observed for all the characters in all the cultivars used in the experiment. All the characters showed high　heritability coupled with high genetic advance. Heritability (h(2)) is an approximate measure of the expression of a character. The highest estimates of broad sense heritability (h(2)= 0.90) and relative expected genetic advance (85.72%) were noted for root dry matter (RDM), while the estimate of expected genetic advance at 10% selection intensity was quite high (ΔG = 85.30c㎡) for leaf area per plant. The estimates of coheritability were positive and relatively higher for rootshoot ratio (RSR) in combination with shoot dry matter (SDM) (coh(2) = 2.002) and phosphorus use efficiency (PUE) (coh(2) = 1.875), whereas coheritability estimates were negative between leaf area per plant and RSR (coh(2) = -0.2010) indicating lack of association between these traits. High heritability with high genetic advance was exhibited by all the studied plant traits of cultivars evidencing that the traits could be further improved through individual plant selection. The innate variations within the Brassica gene-pool impel to drive a concentrated effort to understand the basis of adaptability. Access to the relevant genetic traits and information will provide necessary tools to select the optimal combinations of alleles adapted to local and changing growing environments especially nutrient stress conditions such as phosphorus (P) starvation. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=AkhtarM.

These complicated but elegant morphological, physiological, biochemical and molecular adjustments of Pi-starved plants provide an excellent example of how the unique flexibility of plant metabolism and energy transduction helps them to cope in a typically stressful environment. Pi-starved roots possess enhanced H(+)-ATPase and PEPCase which could result in increasing H(+) efflux and OAs exudations in the root vicinity. This would lead to the rhizosphere acidification, which thereby contribute to the solublization and assimilation of mineral Pi from environment. To visualize the dissolution of sparingly soluble Ca-phosphate and rhizospheric pH changes (in situ), genetically diverse Brassica cultivars were grown on agar media. Newly formed Ca-phosphate was suspended in agar containing other essential nutriens. With NH(4)(+) applied as the N source, the precipitate dissolved in the root vicinity and this was ascribed to acidification. No dissolution was occurred with No(3)(-)-nutrition. In order to observe the pH changes at the media-root interface (rhizosphere), an image analysis was carried out after embedding the roots in agar containing bromocresol purple as pH indicator. Efficient cultivar 'Brown Raya' showed greater decrease in pH than P-inefficient 'B.S.A' in the culture media. Hydroponically grown cultivars were compared with respect to P-utilization efficiency (PUE), P-stress factor (PSF), and Ca- and P-uptake at P-starvation. PUE, and Ca- and P-uptake correlated significantly (P<0.01) with biomass accumulation, indicating that higher P-uptake of efficient cultivars was because of their higher Ca-uptake, which in turn was related to their better P-acquisition and PUE. Remodelling of root architecture of efficient cultivars helped the cultivars to establish a better rooting system, which provided basis for tolerance under P-starvation. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=AkhtarM.
