| Abstract | In order to select the salt tolerant cultivars, and to evaluate the effects of some major genes on salt tolerance in barley, 5,182 varieties and 368 isogenic lines were tested by exposing to 1.0 and 0.5M sodium chloride at the seedling stage. The average rating of salt tolerance was higher in varieties from Korea and Japan , but lower in varieties from Nepal and Southwest Asia. When the varieties were grouped by several morphological characters, six-rowed, covered, E type of nonbrittle rachis and uzu type groups were more tolerant than two-rowed, naked, W type and non-uzu type counterparts, respectively. A comparison between the isogenic pairs revealed that the uzu type was more tolerant than non-uzu type, but other major gene pairs did not show any obvious differences. These findings indicate that the uz gene affects the salt tolerance, and diferences between varietal groups characterized by other major genes are due to the difference in the genetic background among these varieties. |

| Abstract | α-Gulcosidase (EC 3.2.1.20) has been purified 2,500-fold taro (Colocasia esculanta Shott) tuber by a procedure incluting fractionation with ammonium sulfate and ethyl alcohl, CM-cellulofine column chromatography, and preparative disc gel electrophoresis. The enzyme readily hydrolyzed maltose, nigerose, malto-oligosaccharides, and soluble starch. However, the enzyme hydrolyzed isomaltose only very weakly. The Km values of the enzyme for maltohexaose and soluble starch were lower than that for maltose. |

| Title Alternative | Secretion of Defensive Substance by Carabidae and Brachinidae |

| Author | Kanehisa, Katsuo| |
| Abstract | The secretion of defensive substances by more than 250 species of carabid and brachinid beetles was investigated, and discussed from a phylogenetical viewpoint. The morphological of secretion glands and secreted components were identified in the genus level. Specific subgenus and species had peculiar characteristics. The pair of defensive organs consisted of many small synthetic lobes, large reservoirs, collecting ducts from lobes to reservoirs and secretion ducts from reservoirs. The pair dust opened at the last sternal intersegmental membrane. There was species specificity in the reservoir shape, synthetic lobe shape and entering site of the collecting ducts into reservoirs. The spherical shape lobes produced short chain fatty acids, the elongated shape lobes produced m-cresol and the thick board shape lobes produced benzoquinones. Two types of fatty acid-secreting beetles were found, one secreted formic acid, and the other mixed short chain fatty acids. These short chain fatty acids were metabolized from some amino acids, methacrylic acid was from valine; tiglic acid, α-ethyacrylic acid and angelic acid were from isoleucine; senecioic acid was from leucine and crotonic acid was from lysine. These unasaturated acids were sometimes detected with a trace amount of corresponding saturated acids. A few species secreted larger amounts of saturated acids with a trace amounts of unsaturated acids. Fatty acid composition was generally genus-specific. In a few cases, however, species-specific acid composition was also observed. m-Cresol-secreting beetles were observed only in Panagaeni and Chlaeniini except subgenus Chlaenius Chlaeniini except subgenus Chlaenius Chlaeniellus beetle. 1,4-Benzoquinone and 2-methyl-1,4-benzoquinone-secreting beetles were observed in subgenus C. Chlaeniellus. This beetle secreted these substances at body temperature from a reservoir with no sound. Brachinidae beetles, called bombardier beetles, have a pair of brownish reaction chamber connected with a reservoir. They sprayed the two benzoquinones at about 100℃ making sound. |

| Abstract | Pectic polysacchasides from the starch-free cell wall preparation of rice (Oryza sativa) shoots have been extracted in sequence with cyclohexane-trans-1,2-diaminetetra-acetate(CDTA)and Na2CO3. The total amount of polysaccharides extracted with the agents was estimated as approximately 1% of the cell walls. The extracted polysaccharides were fractionated by DEAE-Trisacryl M ion-exchange chromatography yielding five fractions, and the monosaccharide composition and molecular mass were constructed from homogalacturonan and rhamnogalacturoanan containing the "hairy" region with galactosyl and arabinosyl side-chains. The solubilized pectic polysaccharides after treatment with two pectolytic enzymes accounted for 0.4～0.6% of the starch-free cell walls. |

| Abstract | A potyvirus, isolated from Habenaria radiaata showing severe mosaic in the leaves named habenaria mosaic virus(HaMV). HaMV was transmitted by inoculation of sap to 6 of 41 species from 4 of 12 families. Systemic infection was cauded in Habenaria radiata, and local infection was produced in Chenopodium amaranticolor, C. quinoa, Spinacia olracea, Tetragonia expansa and Gomphrena globosa. HaMV was also transmitted by Myzus persicae in a non persistent manner, but not by Aphis gossypii. The virus has filamentous particles of c. 750×13nm. Sap from inoculated C. quinoa was infective after dilution to 10-5 but not 10-6, after 10 min at 60℃ but 65℃, or after 8-16 days at 20℃.In ultrathin sections of diseased leaves of Habenaria radiata and inoculated C. quinoa, virus particles were found to disperse in the cytoplasm. Cylindrical inclusions were present in the cytoplasm of infected cells, as pinwheels, scrolls or tubes. The inclusions observed in negatively stained crude sap preparations exhibited fine linear striation at about 5.2 nm intervals.The antiserum to HaMV produced by immunizing a rabbit had a titer of 1/512(precipitin test). HaMV showed distant serological relationships to potyvirus;alstroemeria mosaic virus, bean yellow mosaic virus, calanthe mild mosaic virus, clover yellow vein virus, dendrobium mosaic virus, freesia mosaic virus, turnip mosaic virus and watermelon mosaic virus 2. |

| Abstract | Rove beetles have a pair of pygidial excretory organs, each group secretes characteristic substances in a peculiar manner. The genus Stenus has a pair of pygidial organs, eversible by immersion in diethyl-ether at both sides of the anus. S. anthoracinus, S. melanarius vercecundus and S. rufescens were collected at ponds and river shores, and S. alienus was collected at tobacco and vegetable fields. Excretory substances were secreted in the diethylether, and identified by gas chromatography and mass spectrometry. Stenusin [N-Ethyl-3-(2-methylbutyl) piperidine], 1,8-cineole, isopiperitenol and 6-Me-5-hepten-2-one were identified. These may probably act as defensive substances against small attacking animals and microorganisms, and act as water suface moving active agents. |

| Abstract | 2,4-Dihydrox-7-methoxy1,4-benzoxazin-3-one (DIMBOA), a hydroxamic acid is considered to be one of the components responsible for the resistance to pest insects in cereal plants. The relationship between concentration of DIMBOA and aphid infestation on 21 corn lines was investigated in 1990 and 1991. DIMBOA was detected in leaves od all corn lines tested, contained larger amounts in young plants and gradually decreased with growth. This property was the same as observed in wheat. A more than ten times difference in DIMBOA concentration was observed in corn lines. However, there was no positive correlation between DIMBOA concentration and aphid density. Most of the lines used had resistance to aphids. Resistance may be built together with other components such as (E)-aconitic acid. |

| Abstract | Temperatures of tree's leaves and gate wall were measured in the summer of 1996 at doline. Diurnal fluctuations of leaf temperatures were greater, the higher the position of leaf in the doline, and they showed maximum temperatures later, the deeper the leaf position. The leaf temperature of trees growing in the first collapse doline was uniform in the horizontal direction and had a stable thermal layer. The difference between leaf temperatures at a depth of 20 m and 11 m was about 12℃ around noon. The leaf temperature was always higher at the upper part than at the lower part of the doline throughout the day. Daily fluctuation of wall temperature was small,compared with that of leaf temperature. The vertical profile of wall temperature was similar to that of leaf temperature. The warm water flowing down from the upper part of the doline influenced the soil temperature in the lower part of the doline. The thermal imagery elucidated the peculiar vertical structure of leaf and wall temperature formed in the summer at Rashomon doline. |

| Abstract | To beer barley resistance to cereal aphids, the relationship between the aphid density and gramine concentration was examined in various barley lines including beer barley cultivars. All beer barley cultivars tested were resistant or moderately resistant to the aphids, especially Asahi 5 and Haruna Nijo were similar to a wild line, H603 (W603), for checking resistant. However, these beer barleys contained much less gramine than the wild barley line, suggesting that another resistant factor(s) affects cereal aphid density. |

| Abstract | The exposure of the caryopsis through lemma and palea is called 'hull-cracked grain', which lowers the germinability and grade of malting barley. To breed new varieties with a low occurence of hull-cracked grains,quantitative trait loci(QTL) analysis was conducted using 146 doubled haploid lincs derived from Harrington × TR306.Interval mapping analysis revealed three significant QTLs on chromosomes 3H,5H and 7H. About 37% of the variation of the expressvity of hull-cracked grains was explained by these three QTLs in a spikelet-thinning condition where 1/4 of the spikelets were thinned at the flowering time. On the contraty the QTL on 5H was silent in normal or non-treated condition and 23% of the variation was determined by the QTLs on 3H and 7H. Some of the QTLs detected here had a pleiotropic effect on the grain size. |

| Abstract | The relationship between the indole alkaloid gramine concentration and aphid population was examined seedling and maturation stages in 14 barley lines of Hordeum spontaneum and H. unlgare. The density of Schizaphis graminum did not differ significantly with the gramine concentration in the seedling in the greenhouse. However, the population of Rhopalosiphum padi sometimes differed with the seedling. The plant resistance to the natural infestation of cereal aphids was obvious at the heading stage. There was a negative correlation between the high population density of aphids and gramine concentration. The gramine concentration was high in matured resistant resistant lines, especially wild lines, as compared with susceptible lines due to higher biodegradation activity. |

| Abstract | Using 10,473 barley accessoins and 16,480 gamma-ray lines, root fluorescence mutants which have been reported in order crops, such as soybean, were screened. No spontaneous mutant was found,but an artificial mutant whose root tips emitted a pink glow under ultraviolet light was obtained by the gamma-ray irradiation. The mutant was controlled by a recessive gene named frp 'fluorescent reaction-pink'. It was poor growth and was lethal. The transmissoin rate of the mutant gene was about 80% of that of the normal allele. Thus the segregation in the heterozygous populations was ca. 4 normal to 1 mutant. The frp gene is located close to gl-3, 'glossy leaf-3' on the 4H chromosome. |

| Abstract | The reproduction of Myzus persicae (Sulz.) on raddish and Aphis gossypii Glover on cucumber was studied at different temperatures. The parameters of population growth in these aphids were calculated by the age-specific fecundities (mx) and survival rate (lx). The net reproductive rate (R0) and intrinsic rate of natural increase (r) of M. persicae were 61.50 and 0.21 at 15℃, and 60.60 and 0.33 at 20℃, respectively. The net reproductive rate (R0) and intrinsic rate of natural increase (r) of A. gossypii were 37.90 and 0.22 at 15℃, 45.70 and 0.32 at 20℃, and 40.60 and 0.42 at 25℃, respectively. |

| Author | Miyashita, Koichi| Maitani, Toshihiko| |
| Abstract | Micrometeorological observations including turbulent fluxes and canopy surface temperatures were made in paddy in the summer of 1997. The sensible and latent heat fluxes were estimated by the gradient method under the assumption of similarity between the turbulent exchange coefficient for momentum and that for heat and water vapor. The surface temperatures measured by a thermal imager and water vapor pressures estimated from surface temperatures and relative humidity were used for temperature and water vapor at the height(d+z0) of U=0, where d is the displacement height, z0 the roughness length and U the mean wind velocity. The sensible and latent heat fluxes estimated by the gradient method depicted typical diurnal varietions. The turbulent fluxes by the present method and eddy correlation method showed fairly good agreement, especially for latent heat fluxes. These results confirmed that this method is a promising one. |

| Abstract | The thrips Ponticulothrips diospyrosi Haga et Okajima is an univoltine species which aestivates and overwinters in the adult form in the fields. The oviposition factors of the thrips were investigated on persimmon seedling leaves. The adult female could make a gall and oviposit inside it in vitro. Female could make a gall and oviposit at 20℃, but only make a gall at 15℃. Although it could neither make a gall nor oviposit at 25℃, it oviposited at than temperature when placed on a gall. Female neither made a gall nor oviposited on an extended young leat. However, it could oviposit on the young leaf rolled artificially in a line tube (3.2 mm diam.), but not on the old one. These findings show that univoltine of the thrips may be regulated by the phenology of the host plant and females can oviposit whenever they are placed on the seedlings at the optimum oviposition temperature. |

| Abstract | The influences of air temperature, precipitation, number of rainy days and sunshine duration on the crop situation index of wheat, six-rowed barley and two-rowed barley in Okayama prefecture were analyzed by using the data for the 30-year-period of 1966-1995. The crop situation index of these three crops showed high negative correlation with the precipitation in April and a positive correlation with sunshine duration in April. Precipitation over 150 mm or lesser sunshine duration under 190 hrs in April seems to reduce the yield of wheat and barley in Okayama. |

| Abstract | Young leaves of barley contain a large amount of gramine, which is one of the factors involved in the resistance of barley against aphids. Using stylectomy by laser beam and EDTA-exudate method, we tried to determine if gramine exists in phloem sap which aphids ingest mainly. Phloem sap was not obtained by laser stylectomy using aphids feeding on young leaves. Components of exudates from cut leaves of barley in EDTA solution are known to be very similar to phloem sap. The time course of sucrose and gramine content of EDTA exudates from barley leaves suggested the existence of gramine in phloem sap. |

| Abstract | To determine the relationship between morphological markers and salt tolerance at germination in barley (Hordeum vulgare L.), a total of 125 recombinant inbred (RI) lines of Russia 6×HES 4, a seriesof 70 isogenic (IG) lines for V/ν gene derived from Russia 6×HES 4, and 145 doubled haploid (DH) lines of Leger×CI 9831 were evaluated for their salt tolerance at germination. Comparison between each set of character pairs revealed that the six-rowed type was significantly more tolerant than the two-rowed type in the RI and IG lines of Russia 6×HES 4, annd the two-rowed type and the short haired rachilla type were significantly more tolerant than the six-rowed type and the long haired rachilla type in the DH lines of Leger×CI 9831. On the other hand, no significant difference was observed in salt tolerance such as the smoothness of awn, ear density, and lemma color, r (awn type), l (ear density), and Re-2 (lemma color) genes inherited independent of gene(s) for salt tolerance at germination. |
