Our previous study indicated that cold PEG?primed Eustoma seeds could maintain their germination rate and bolting rate even after being re?dried for 30days and grown under high temperatures. The present study aimed to investigate whether prolonged storage after cold PEG?priming affect the germination, growth, and flowering of Eustoma ‘Exe Lavender’ seedling. Seeds were initially cold?primed with water or PEG?6000 at ?1.5 MPa for 5 weeks at 10°C in the dark and were then subjected to re?drying and storage for 30, 60, 90 and 360days at 10°C. After 360days of storage, cold PEG?primed seeds germinated earlier and more effectively than cold hydro?primed seeds. Compared to the results after 30days of storage, plants grown from 360days exhibited similar bolting rate, days to bolting, bolting node and flowering rate, cut flower length and number of flower node. These results suggest that ‘Exe Lavender’ seeds can germinate and develop well even after 360days of storage and under high temperature conditions when subjected to cold PEG?6000 treatment. en-copyright= kn-copyright= en-aut-name=PhanThao Thu en-aut-sei=Phan en-aut-mei=Thao Thu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FukushimaKeigo en-aut-sei=Fukushima en-aut-mei=Keigo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanakaYoshiyuki en-aut-sei=Tanaka en-aut-mei=Yoshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YasubaKen-ichiro en-aut-sei=Yasuba en-aut-mei=Ken-ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YoshidaYuichi en-aut-sei=Yoshida en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=GotoTanjuro en-aut-sei=Goto en-aut-mei=Tanjuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Hiroshima Prefectural Technology Research Institute, Agricultural Technology Research Center kn-affil= affil-num=3 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=bolting kn-keyword=bolting en-keyword=chilling kn-keyword=chilling en-keyword=dehydrate kn-keyword=dehydrate en-keyword=long storage kn-keyword=long storage en-keyword=PEG-6000 kn-keyword=PEG-6000 END start-ver=1.4 cd-journal=joma no-vol=91 cd-vols= no-issue=1 article-no= start-page=58 end-page=67 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220122 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Fasciation in Strawberry Floral Organs and Possible Implications for Floral Transition en-subtitle= kn-subtitle= en-abstract= kn-abstract=Fasciation in strawberry is characterized by an enlarged and flattened receptacle, clustering of flowers, and altered inflorescence architecture. However, the developmental process of fasciated flowers remains obscure. In this study, the fasciation incidence and developmental process in the primary fruit and inflorescence architecture were evaluated and compared for the non-susceptible cultivars, ‘Nyoho’ and ‘Sagahonoka’ and one of the most susceptible cultivars, ‘Ai-Berry’. The severity and frequency of flower and inflorescence fasciation was clearly greater in the vigorously growing large plants of ‘Ai-Berry’ compared to small plants and large plants of the other two cultivars. In ‘Ai-Berry’, the deformation of the large shoot apical meristem (SAM) into an oval shape was the initial symptom observed before and during floral transition. Such oval-shaped SAMs often differentiated two or more leaf primordia almost at the same time, which then developed into divided multiple vegetative SAMs before floral transition and linearly-fasciated SAMs during floral transition, respectively. The development of fasciation symptoms was observed after downregulation of FaTFL1. Although inflorescence or receptacle fasciation could be controlled when early and rapid floral induction was achieved by intermittent low-temperature treatment, severe fasciation was observed in late-flowered plants which were either not responsive or not subjected to this treatment. These results indicate that fasciation of floral organs may be triggered and develop during floral transition and that temperature fluctuations around boundary values between floral inhibition to induction may cause a half-finished or slowly processed floral transition and finally result in severe fasciation in vigorously growing ‘Ai-Berry’ plants. en-copyright= kn-copyright= en-aut-name=Thi CamNguyen en-aut-sei=Thi Cam en-aut-mei=Nguyen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SunagawaNaomichi en-aut-sei=Sunagawa en-aut-mei=Naomichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SesumiMiho en-aut-sei=Sesumi en-aut-mei=Miho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KitamuraYoshikuni en-aut-sei=Kitamura en-aut-mei=Yoshikuni kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanakaYoshiyuki en-aut-sei=Tanaka en-aut-mei=Yoshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=GotoTanjuro en-aut-sei=Goto en-aut-mei=Tanjuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YasubaKen-ichiro en-aut-sei=Yasuba en-aut-mei=Ken-ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YoshidaYuichi en-aut-sei=Yoshida en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Sciences, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Sciences, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental and Life Sciences, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental and Life Sciences, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Agriculture, Kyoto University kn-affil= affil-num=6 en-affil=Graduate School of Environmental and Life Sciences, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Environmental and Life Sciences, Okayama University kn-affil= affil-num=8 en-affil=Graduate School of Environmental and Life Sciences, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=89 cd-vols= no-issue=1 article-no= start-page=22 end-page=29 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=2020 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effect of Defoliation on Blossom-end Rot Incidence and Calcium Transport into Fruit of Tomato Cultivars Under Moderate Water Stress en-subtitle= kn-subtitle= en-abstract= kn-abstract=The translocation of calcium (Ca) within the tomato plant and the causes of Ca deficiency, a factor associated with blossom-end rot (BER) in fruit, are still a matter of conjecture. The objective of this study was to determine the effect of defoliation on BER incidence and Ca transport into different size tomato fruit cultivars. Four experiments were conducted. The start and end dates for each experiment were; 14 March?2 May, 22 July?23 August, 30 August?7 October 2017, and 20 May?25 June 2018, for experiments 1, 2, 3, and 4, respectively. Five tomato cultivars including one large (‘Momotaro fight (MF)’, ? 200 g), three medium (‘Lui 60 (L60)’, ‘Tio cook (TC)’, and ‘Cindy sweet (CS)’, 30?80 g), and one small (‘Pepe (PP)’, ? 20 g) fruit cultivars, respectively, were grown under moderate water stress controlled by a combination of root zone restriction and solar mediated fertigation. Leaf area of plants was reduced by 20?30% by removing alternate leaflets on all leaves. Defoliation significantly reduced BER in all experiments. In experiment 4, no BER was observed in defoliated plants of L60 and PP, and in MF and TC, BER incidence decreased to a quarter of the control. Defoliation increased the fruit growth rate (FGR) in experiment 1, in which the temperature was the lowest, by a ratio of 1.42 and by 1.39 in experiment 4, in which the radiation was strongest and day length longest. Defoliation increased the rate of daily Ca transport into fruit (CTR) in MF, L60, TC, CS, and PP by average ratios of 1.64, 1.55, 1.35, 1.30, and 1.13, respectively. The increase in CTR in defoliated plants was highest in experiment 4 with a ratio of 1.68 followed by 1.37, 1.33, and 1.28 in experiments 1, 3, and 2, respectively. Defoliation increased both FGR and CTR and there were significant linear relationships between them. However, the degree of increase was larger in CTR than that in FGR, especially in the BER-sensitive large fruit cultivar MF, and defoliation increased the total Ca concentration in fruit accordingly. We conclude that under moderate water stress by root zone restriction and certain other BER inductive conditions, defoliation could be a promising approach to reduce BER incidence by improving Ca nutrition in susceptible large fruit cultivars. en-copyright= kn-copyright= en-aut-name=IndecheAnnah Khatenje en-aut-sei=Indeche en-aut-mei=Annah Khatenje kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshidaYuichi en-aut-sei=Yoshida en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=GotoTanjuro en-aut-sei=Goto en-aut-mei=Tanjuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YasubaKen-ichiro en-aut-sei=Yasuba en-aut-mei=Ken-ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanakaYoshiyuki en-aut-sei=Tanaka en-aut-mei=Yoshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=109 cd-vols= no-issue= article-no= start-page=21 end-page=27 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Defoliating to 12-15 leaves increases calcium concentration and decreases blossom-end rot incidence in fruit of tomato plant grown under moderate water stress en-subtitle= kn-subtitle= en-abstract= kn-abstract= The objectives of this study were to (i) determine the optimum number of whole leaves to retain on a tomato plant for effective blossom-end rot (BER) management and (ii) explore the relationship between shoot calcium (Ca) and fruit Ca in non-defoliated plants in two different sized fruit cultivars, a large-fruited cultivar ‘Momotaro fight’ and a medium-fruited cultivar ‘Cindy sweet’. Treatments involved maintaining 18, 15 and 12 leaves on a plant. All lateral shoots were removed regularly throughout the growing period except the shoot closest to the flowering truss in the 18-leaf treatment. At the length of 10cm, these shoots were sampled for real time Ca determination using a hand held Ca2+ meter. In the plants defoliated to 18 leaves, BER was higher in ‘Momotaro fight’ at 10% compared to 2% in ‘Cindy sweet’. Fruit growth rate was significantly increased by defoliation in ‘Momotaro fight’, however no significant difference was observed among treatments in ‘Cindy sweet’. Defoliating to 12 leaves increased daily Ca transport rate by 59% and 37% in ‘Momotaro fight’ and ‘Cindy sweet’, respectively. Defoliating to 12 leaves increased the water-soluble Ca concentration in the distal part of fruit by 34% and 14% in ‘Momotaro fight’ and ‘Cindy sweet’, respectively. In the plants defoliated to 18 leaves where only old yellowish leaves were removed, a significant steady decrease was observed in the concentration of water soluble Ca in the distal part of fruit with increase in truss order. There was a significant linear relationship between water-soluble Ca concentration in the distal part of the fruit and Ca concentration in the lateral shoot of plants defoliated to 18 leaves. We conclude that under moderate water stress by root zone restriction and also certain other BER inductive conditions, defoliation to 12?15 leaves on a tomato plant should be a promising approach for decreasing BER incidence in susceptible large fruit cultivars. en-copyright= kn-copyright= en-aut-name=Annah Khatenje Indeche en-aut-sei=Annah Khatenje Indeche en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshidaYuichi en-aut-sei=Yoshida en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MiyajiDaisuke en-aut-sei=Miyaji en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=GotoTanjuro en-aut-sei=Goto en-aut-mei=Tanjuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YasubaKen-ichiro en-aut-sei=Yasuba en-aut-mei=Ken-ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TanakaYoshiyuki en-aut-sei=Tanaka en-aut-mei=Yoshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate school of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate school of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Field Science Center kn-affil= affil-num=4 en-affil=Graduate school of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Graduate school of Environmental and Life Science, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Agriculture, Kyoto University kn-affil= en-keyword=BER management kn-keyword=BER management en-keyword=defoliation kn-keyword=defoliation en-keyword=water-soluble Ca kn-keyword=water-soluble Ca en-keyword= lateral shoot Ca kn-keyword= lateral shoot Ca en-keyword=root zone restriction kn-keyword=root zone restriction END start-ver=1.4 cd-journal=joma no-vol=108 cd-vols= no-issue= article-no= start-page=5 end-page=13 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20190201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Effect of boron deficiency on tip burn and malformed fruit incidence in strawberries kn-title=B（ホウ素）欠乏処理がイチゴのチップバーンおよび受精不良果発生に及ぼす影響 en-subtitle= kn-subtitle= en-abstract=　B（ホウ素）は植物にとって必須な微量要素であり，イチゴの受精不良果発生要因の1 つである．そこで2015年度と2016年度の2 回にわたりB 欠乏がイチゴの受精不良果発生に及ぼす影響について調査した．また，2016年度はB 欠乏処理後にB 回復処理を行い，その後のイチゴの果実形態の変化についても調査した．その結果，B欠乏処理を行うと蒸散機能の低い新葉や花芽においてチップバーンが発生し，種浮き果や部分不受精を主とした受精不良果が多発した．しかし，B 回復処理を行うことでこれらの症状が改善することが明らかになった．B は受精不良果発生に関係しており，欠乏条件下で根から吸収させると急速に若い成長中の組織に転流することが示されたことから，B 栄養をコントロールすることでB 不足によるイチゴの受精不良果発生を軽減できる可能性があると考えられる． kn-abstract=Boron (B) is an essential micro element for plants and plays important roles in the synthesis and functions of cell wall. B deficiency has been reported as one of the causes of fruit malformation in strawberries. We investigated the effect of B deficiency on flower and fruit development of forced strawberries for two cropping seasons (2015-2017). In the second season, B was resupplied for B-deficient plants and we investigated changes in fruit development. When B-free nutrient solutions were supplied, tip burn began to occur in newly emerging leaves and calyx 2 to 3 months later, and fruit malformation including seedy or only partly developed fruits with undeveloped achenes occurred frequently. However, these deficient symptoms were quickly disappeared by supplying B containing nutrient solutions. In conclusion, B nutrition is closely related to the occurrence of fruit malformation through fertility of pollen and pistils, and also development of receptacle tissue in strawberries. It should be possible to reduce fruit malformation in strawberries by proper control of B nutrition. en-copyright= kn-copyright= en-aut-name=SesumiMiho en-aut-sei=Sesumi en-aut-mei=Miho kn-aut-name=瀬角美穂 kn-aut-sei=瀬角 kn-aut-mei=美穂 aut-affil-num=1 ORCID= en-aut-name=YoshidaYuichi en-aut-sei=Yoshida en-aut-mei=Yuichi kn-aut-name=吉田裕一 kn-aut-sei=吉田 kn-aut-mei=裕一 aut-affil-num=2 ORCID= en-aut-name=KinjoAkari en-aut-sei=Kinjo en-aut-mei=Akari kn-aut-name=金城朱理 kn-aut-sei=金城 kn-aut-mei=朱理 aut-affil-num=3 ORCID= en-aut-name=HidakaKei en-aut-sei=Hidaka en-aut-mei=Kei kn-aut-name=日高啓 kn-aut-sei=日高 kn-aut-mei=啓 aut-affil-num=4 ORCID= en-aut-name=GotoTanjuro en-aut-sei=Goto en-aut-mei=Tanjuro kn-aut-name=後藤丹十郎 kn-aut-sei=後藤 kn-aut-mei=丹十郎 aut-affil-num=5 ORCID= en-aut-name=YasubaKen-ichiro en-aut-sei=Yasuba en-aut-mei=Ken-ichiro kn-aut-name=安場健一郎 kn-aut-sei=安場 kn-aut-mei=健一郎 aut-affil-num=6 ORCID= en-aut-name=TanakaYoshiyuki en-aut-sei=Tanaka en-aut-mei=Yoshiyuki kn-aut-name=田中義行 kn-aut-sei=田中 kn-aut-mei=義行 aut-affil-num=7 ORCID= affil-num=1 en-affil=Graduate school of Environmental and Life Science 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 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 kn-affil=岡山大学大学院　環境生命科学研究科 affil-num=4 en-affil=Asahi Kagaku Kogyo Co., Ltd.) kn-affil=旭化学工業 affil-num=5 en-affil=Graduate school of Environmental and Life Science kn-affil=岡山大学大学院　環境生命科学研究科 affil-num=6 en-affil=Graduate school of Environmental and Life Science 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 kn-affil=岡山大学大学院　環境生命科学研究科 en-keyword=floral organs kn-keyword=floral organs en-keyword=Fragaria × ananassa Duch. kn-keyword=Fragaria × ananassa Duch. en-keyword=pistil fertility kn-keyword=pistil fertility en-keyword=receptacle growth kn-keyword=receptacle growth en-keyword=seedy fruit kn-keyword=seedy fruit END start-ver=1.4 cd-journal=joma no-vol=106 cd-vols= no-issue= article-no= start-page=27 end-page=32 dt-received= dt-revised= dt-accepted= dt-pub-year=2017 dt-pub=20170201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=トウガラシ（Capsicum baccatum）における カプサイシノイド含量の変異とその非辛味系統 kn-title=Variations in capsaicinoid contents in the chili pepper (Capsicum baccatum) and its non-pungent accessions en-subtitle= kn-subtitle= en-abstract=　トウガラシ（Capsicum 属）は世界的に重要な香辛料および野菜である．C. baccatum は南米原産のマイナーな栽培種であるが，果色，果形や辛味など果実形質に多様性が認められることから，トウガラシ遺伝資源として注目されている．トウガラシの辛味性についてはC. annuum 種において多くの研究が行われているが，C. baccatum 種においては十分研究されていない．

C. baccatum is a lesser known domesticated species that is native to the Andean region. Fruit traits such as color, shape, and pungency markedly vary in this species. C. baccatum has potential as a bioresource for future chili pepper breeding programs. Although extensive studies have been conducted on the pungency of C. annuum, that of C. baccatum has not been examined in as much detail. In the present study, capsaicinoid contents were analyzed in 36 C. baccatum accessions. Capsaicinoid contents ranged between 0 and 4,258 μg/gDW. Furthermore, a negative relationship was observed between capsaicinoid contents and fruit weights. Although the pungency of C. baccatum is regarded as low-mild, very few non-pungent accessions were detected ; only one non-pungent accession (‘Kaleidoscope’) was identified among the C. baccatum accessions examined. In order to validate the stability of non-pungency in the accession, capsaicinoid contents were determined at different harvest dates, along with other accessions with different pungencies. Although capsaicinoid contents in other C. baccatum accessions changed with the picking date, capsaicinoid was not detected in ‘Kaleidoscope’ at any date. The non-pungent accession reported here may be useful for future C. baccatum pepper breeding programs. en-copyright= kn-copyright= en-aut-name=TanakaYoshiyuki en-aut-sei=Tanaka en-aut-mei=Yoshiyuki kn-aut-name=田中義行 kn-aut-sei=田中 kn-aut-mei=義行 aut-affil-num=1 ORCID= en-aut-name=HaraMotohito en-aut-sei=Hara en-aut-mei=Motohito kn-aut-name=原一仁 kn-aut-sei=原 kn-aut-mei=一仁 aut-affil-num=2 ORCID= en-aut-name=GotoTanjuro en-aut-sei=Goto en-aut-mei=Tanjuro kn-aut-name=後藤丹十郎 kn-aut-sei=後藤 kn-aut-mei=丹十郎 aut-affil-num=3 ORCID= en-aut-name=YoshidaYuichi en-aut-sei=Yoshida en-aut-mei=Yuichi kn-aut-name=吉田裕一 kn-aut-sei=吉田 kn-aut-mei=裕一 aut-affil-num=4 ORCID= en-aut-name=YasubaKen-ichiro en-aut-sei=Yasuba en-aut-mei=Ken-ichiro kn-aut-name=安場健一郎 kn-aut-sei=安場 kn-aut-mei=健一郎 aut-affil-num=5 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=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=Bio-resource kn-keyword=Bio-resource en-keyword=Fruit shape kn-keyword=Fruit shape END start-ver=1.4 cd-journal=joma no-vol=106 cd-vols= no-issue= article-no= start-page=21 end-page=25 dt-received= dt-revised= dt-accepted= dt-pub-year=2017 dt-pub=20170201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Effect of Beginning Date of Intermittent Low Temperature Treatments on Flowering of Tray-grown Strawberry 'Nyoho' kn-title=処理開始時期がトレイ育苗したイチゴ‘女峰’に対する 間欠冷蔵処理の効果発現に及ぼす影響 en-subtitle= kn-subtitle= en-abstract= kn-abstract=　Intermittent low temperature storage is expected to be a new artificial flower-inducing treatment and becoming to be a practical procedure as it does not require expensive equipment or much energy cost.

Plants were transferred at noon and this cycle was repeated twice (3D/3D). Such 3D/3D treatments were begun on August 22, 25, 28, 31, and September 3and the effectiveness on flowering was determined for 2 years.

Continuous 6 days of 15°C storage (6D) was effective to some extent, but 6D from August 25 was apparently less effective compared to those begun later. Both in intermittent and continuous treatments for ‘Nyoho’, it was confirmed that any flower-inducing effect became relatively small and unstable when the treatments were begun before 28 August in

system kn-title=施設栽培における潜熱利用に関するコンピュータ利用技術の開発 en-subtitle= kn-subtitle= en-abstract= kn-abstract=　In protected horticulture, cooling techniques with latent heat has been effective for improving the growth of various kinds of plants in the summer season. It was necessary to understand special knowledge of the VETH diagrammatic drawing for effective operation of cooling with latent heat. In order to obtain the information from VETH diagrammatic drawing, it was necessary to perform a lot of calculations. It was difficult to obtain such information simply. So, a device and software were developed for getting effective information in order to manage cooling of latent heat. The developed device and software were run on the Ubiquitous Environment Control System (UECS). The rules for controlling the environment of UECS was were set up on a web site, and an information communication technique was used for controlling the environment. The developed ventilation calculated node gathered the necessary information from the other nodes via LAN automatically. The node calculated valuable information for cooling with latent heat, including the ventilation rate, and sent the calculated values, after entering the constant parameters using an http server, which was installed in the node. The developed software was run on a personal computer. The software could be used after describing various information for calculating ventilation rate and evaporation rate at the setting file. It calculated these values, and users were shown the data using graphs and text files. As a result, we could get effective information concerning cooling latent heat fairly easily by using of the developed node and the software. en-copyright= kn-copyright= en-aut-name=YasubaKen-ichiro en-aut-sei=Yasuba en-aut-mei=Ken-ichiro kn-aut-name=安場健一郎 kn-aut-sei=安場 kn-aut-mei=健一郎 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学農学部 en-keyword=latent heat kn-keyword=latent heat en-keyword=computer kn-keyword=computer en-keyword=fogging kn-keyword=fogging en-keyword=ubiquitous environment control system kn-keyword=ubiquitous environment control system END
