| Abstract | Absorption rares of ammonium ion(NH4+) and nitrate ion(NO3-) for 24 hours were compared using two absorption solutions, which were a single salt solution of ammonium nitrate (NH4NO3) and a complete nutrient solution containing NH4NO3. Test plants were Oryza sativa (Rice), Hordeum vulgare (Barley), Lactuca sativa (Lettuce), Cucumis sativus (Cucumber), Daucus carota (Carrot), Brassica pekinesis (Chinese cabbage), Spinacia oleracea (Spinach) and Raphanus sativus (Radish). From the absorption characteristics of NH4+ and NO3- between a single salt solution of NH4NO3 and a complete nutrient solution containing NH4NO3, the test plants were classified into goup 1(rice,barley and lettuce), which absorbed NH4+ more rapidly than NO3- in both absorption solutions, group 2(cucumber and carrot), which absorbed NH4+ slightly more than NO3- in the single salt solution of NH4NO3, the tendency of which was reversed in the complete nutrient solution containing NH4NO3, and goup 3(Chinese cabbage,spinach and radish), which absorbed NO3- clealy more than NH4+ in the complete nutrient solution, whereas the absorption of NH4+ or NO3- was almost equal in the single salt solution of NH4+NO3-. The above classisication of plants could be explained by the balance of a repressive or competitive characteristics of NH4+ absorption mainly as sociated with a capacity for absorption of calcium ion(Ca2+) and magnesium ion(Mg2+), and the relative root affinity to NO3- that can be evaluated by the relative absorption of NO3- to mono-phosphate ion(H2PO4-) in plant roots. The group 1 plants are the so-called acid tolerant plants, which appeared to be tolerant to NH4+, and showed a marked pH decreased during the 24 hours of the absorption experiments in those plants. By contrast, the group 3 plant seemed to prefer NO3- and divalent alkaline earth cations to the other nutrients in the complete nutrient solution containing NH4No3, and the pH decrease during each absorption experiment was small. |

| Abstract | The callus forming ability and regenerating ability of the calli derived from mature and immature embryos of 132 barley varieties were examined. These materials were taken from a world-wide collection preserved at the Barley Germplasm Center of Okayama University. The callus forming ability varied widely according to genotype in both mature and immature embryos, but the varieties collected from Ethiopia showed low callus forming ability. Calli derived from mature embryos generally did not regenerate shoots, except for three Japanese varieties. The frequency of shoot regeneration from the calli derived from immature embryos was somewhat higher than that from those derived from mature embryos. Many of the Korean and Japanese varieties had a high shoot regenerating ability. However, few of the varieties from Ethiopia and Southwest Asia had a high shoot regenerating ability. No correlation was observed btween root regenerating ability and shoot regenerating ability of the varieties. No correlation was observed between callus proliferation and root regenerating ability between calli derived from mature and immature embryos. We could not find any difference in the shoot regenerating ability btween the two-rowed and six-rowed genotypes. |

| Abstract | 我が国では、戦前から戦後にかけてオオムギ栽培が盛んに行われたが六条オオムギが主であった。しかし、昭和30年代になると醸造用あるいは飼料用として二条オオムギの栽培が盛んになり、最近では従来の六条オオムギから二条オオムギにほとんど置き替わっている。我が国における二条オオムギは明治以後欧州あるいは米国から導入された品種が、選抜を受けたり交配母本に用いられて定着したもので、我が国在来の六条オオムギにくらべて歴史は新しく（高橋ら1981）。これらの二条品種は日本の風土に適するように改良が加えられていることはもちろんであるが、それにしても、二条性そのものが我が国にはなかった形質であり、春播性、ウドンコ病抵抗性、短毛底刺などいわゆる外来の特徴を併せ持っている。このような外来の形質そのものがどの程度我が国の環境条件の中で生かされ、いわゆる日本化が進んでいるかは、今後の二条オオムギ育種上極めて有用な知見になるものと思われる。そのためには日本で栽培されている二条品種と、外国の二条オオムギの主な分布地域から収集した品種とを比較対照して、生理、遺伝的解析を進める必要がある。本研究はこのような意図の下に行われた。以下に結果の概要を示す。 |

| Abstract | In order to select higher salt tolerant cultivars of barley,solution culture experiments were carried out with 500 barley cultivars, which were preliminarily selected from 4581 cultivars by exposure to 1-2% of sodium chloride(MaCl) during the germinating stage. The concentrations of NaCl used in the experiments were 2 (control), 150 and 300 mM in nutrient solution.From the results of five solution culture experiments, each of which was carried out with about 100 cultivars, 105 cultivars of barley were selected as relatively about 100 cultivars. Then the final selection was carried out on those 105 cultivars, and it was found that more than 10 cultivars were highly salt tolerant, mainly based on the comparisons of shoot yields under the supply of 300 mM of NaCl.High salt tolerant barley cultivars mentioned above showed 42-86% and 17-30% of the control in shoot yield under the condition of 150 and 300 mM of NaCl, respectively.On three groups of barley,each having more than 10 cultivars, which are high, moderate and low in salt tolerance, ion contents of the plants were analyzed.The results suggest that potassium(K) uptake was comparatively larger in the high salt tolerant goup of barley cultivars,through there was a big variation in sodium(Na) and K contents even within the same group. |

| Abstract | A system designed to measure the vegetation response to environment was constructed on the basis of the eddy correlation method.It consisted of two sets of a small rapid response sensors; three dimensional sonic anemometer thermometers and infrared CO2-humidity fluctuation meters,and a personal computer for data acquisition. Field tests of the system were made over a barley field in April and May,1990.The turbulent fluxes obtained by two sets of flux measuring system mounted at the same height were in fair agreement. The turbulent fluxes(momentum,sensible heat,latent heat and carbon dioxide) measured at two height wihtin and above plant cannopies and their differences showed realistic diurnal variations.The direction and magnitude of each flux varied depending on the srength or distribution of source and sink within plant canopies. These findings confirmed that this measureing system is promising for quantitative estimate of vegetation response such as transpiration, photosynthesis and respiration in certain canopy layers to environmental variations. |

| Abstract | To investigate the differences and mechanism of germination among the seeds of some species of genus Echinochloa and rice, the experiments were conducted in solutions of salt, sugar, and PEG(poly-ethylene glycol) under a constant or alternating temperature in the light or the dark. The seeds of Echinochloa oryzicola Vasing., Ehinochloa crus-galli Beauv.var. formosensis Ohwi, Echinochloa crus-galli Beauv.var.crus-galli(awnless and awned type)and Oryza sativa L.(Akebono) were used. In 7000hPa, germination of rice,E. oryzicola and three varieties of E.crus-galli in all the solutions remarkedly decreased except for the case of E.crus-galli in the solution of sale on alternating temperature. The germination of rice and E.oryzicola was secreased markedly, and more markedly in a light condition than in a dark. In the salt solution in 7000hPa, the decreasing of germination of E.crus-galli was low. This species is distributed and grows in the upland and paddy field, while E.oryzicola and rice grow only in the paddy field. The decreade in germination of Echinochloa species with osmotic pressure seemed to be recoverde with salt or sugar solutions under alternating temperature, but the recovery of rice was not seen. In 700hPa or less, the distinct differences of germination were not seen among these plants species. |

| Abstract | Odontoglossum ringspot virus (ORSV)はJensen＆Gold（1951）によってOdontoglossum grandeにえそ輪紋を生じた病原ウイルスに命名されたが、CattleyaやCymbidiumを中心として広くラン科植物に発生していることが認められている。また、わが国では井上（1966、1983）がCymbidiumからORSVを分離し報告しており、日本でも多種属のラン科植物にORSVの発生が非常に多いことが認められている。シュンラン、カンラン、スルガランなどを含む東洋ラン・Cymbidium属では、かつて葉にモザイク斑を生じた斑紋を”金砂”と呼び非常に珍重されていたが、井上（1984、1990）はこの斑紋がORSVの感染によって生じたものであることを記載した。さらに、井上・呂（1983）は台湾においてもORSVが東洋ランに発生していることを報告している。これらの報告にはウイルスの診断と病徴の記載にとどまり、その病原ウイルスの諸性質についての詳細な記述がなされていなかった。本報告では、葉に軽いモザイク症状を示す東洋ランと呼ばれているスルガラン（Cymbidium ensifolium：蕙蘭）およびカンラン（Cymb. kanran）から検出されたウイルスについて病原学的研究を行ったところ、ORSVと同定されたので、これらの諸性質についての研究結果を報告するとともに、この東洋ラン分離株と既報の洋ランから分離されているORSVおよび同グループのtobacco mosaic virus （TMV）との比較研究を行ったので、それらの結果についても報告する。 |

| Abstract | Plant-feeding arthropods, in the course of evolution have adapted differentially to their plant host and thereby gained access to the available resource. Plants responded by developing chemicals and morphological defense to arthropods. Some secondary metabolic substances in plants have been assumed to be toxic or deter feeding. Aconitic acid in the barnyard-grass subspecies, Echinochloa oryzycola Vasing has been reported to be an active component against brown rice planthopper Nilapalvata lugens (Stal) (Kim et al. 1976). Aphids, Ropalosiphum padi. L., R. maidis (F.), Schizaphis graminum (Rondani)and Sitobion akeviae (Shinji), are important pests of barley (Hordeum vulgare L.) and wheat (Triticum aesstivum L.). On barley plants, more than seven aphids per stem causes yield loss (Hansen 1990). R. maidis sometimes severely infested corn plants (Zea mays L.), the leaves being wet by honeydew. Melanaphis sacchari (Zehntner) caused brownish decay of leaves of a susceptible line・ of sorghum Sorghum bicolor Moench. We examined the relation between aconitic acid contents and aphid densities in wheat, barley, corn, sorghum, barnyard grass and rice (Rustamani et al. 1992a). The plants containing larger amounts of aconitic acid showed a moderate degree of resistance to aphids. The findings obtained on additional lines in 1991, and on other components, such as DIMBOA (2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one), are reported herein. |
