Abstract 平成15年度第4四半期「理科授業研究A」受講生を回答者として、「多様な生物」に関する意識と現行の小中学校理科(生活科を含む)教科書に示されている「身近な生物」の身近さの程度とを問うアンケート調査を実施し、回答結果を分析・考察した。小学校教員になろうとする学生として、例えば、教科書で示されている生物の1/3は身近な生物ではなく、1/5は聴いたことさえない生物であること、また、「生物多様性条約」「生物多様性国家戦略」を誰一人として聴いたことがないことからわかるように、環境教育に関わる新しい課題「生物の多様性」に対処していくために必要な知識や関心があるとは言い難かった。教科書で示されている生物に対する検討だけでなく、教員養成に関しても検討が求められるものである。

Title Alternative Measurements of Response of Barley and Wheat to Enviromental Factors with an Open System Porometer
FullText URL 005_001_011_021.pdf
Author Maitani, Toshihiko| Kashiwagi, Yoshiaki|
Abstract The rates of photosynthesis and transpiration were measured in barley and wheat under various environmental conditions, with an open system porometer. The rates of photosynthesis and transpiration in the horizontal leaf and vertical leaf had different diurnal variations. The rate of photosynthesis in the vertical leaf was highest in the morning and in the afternoon, while that in the horizontal leaf was highest before noon. The rates of photosynthesis and transpiration and chlorophyll contents were measured for two species(c.v SARI and Akanmugi) of barley grown in submerged soil conditions. At the end of April, chlorophyll contents had decreased and the maintenance respiration acquired in spite of continuous transpiration. The rapid change of photosynthetically active radiation did not affect the rates of photosynthesis or stomatal conductance of SARI grown in submerged soil. The rates of photosynthesis and transpiration and chlorophyll contents were measured for two species(c.v. Hongmangmai and Haruhikari) of wheat grown under different soil water conditions. Chlorophyll content tended to increase in dry soil conditions. Hongmangmai had a higher chlorophyll content than Haruhikari, even at the beginning of May. Hongmangmai had large photosynthetic rate and small transpiration rates under dry soil conditions. These confirm that Hongmangmai has a prominent drought stress tolerance. The open system porometer and the chlorophyll meter may be very useful for comparing physiological characteristics of the plant's response to environmental factors and clarifying differences between plant species.

Title Alternative Varietal Variation and Mechanism of Hull-cracked Grains in Two-rowed Barley
FullText URL 004_001_089_096.pdf
Author Kanatani, Ryoichi| Takeda, Kazuyoshi|
Abstract Hull-cracked grain which causes low germinability and low malt extract has been observed in malting barley varieties mainly in the western part of Japan. In the first part of this study, more than 600 two-rowed barley varieties were examined for the percentage of hull-cracked grains. A markedly skewed frequency distribution pattern was observed for varietal variation of hull-cracked grain percentage. More than 80% of the varieties developed less than 5% hull-cracked grains, while a few of the varieties frequently developed the hull-cracked grains. The maximum hull-cracked grain percentage was as high as 61% in Yoshikei 16. Improved varieties developed hull-cracked grains more frequently than the local varieties, indicating varietal improvement indirectly caused the hull-cracked grains. In the second part, nine two-rowed varieties were grown in eight different conditions to analyze the mechanism of hull-cracking. Variances due to varieties, environment and their interaction were all statistically significant. Some of the varieties developed almost no hull-cracked grains throughout the environmental conditions examined, while others sharply responded to the environmental conditions. The environmental correlation coefficient between 1,000-kernel weight and hull-cracked grains was as high as 0.918, indicating that hull-cracked grains had developed under favorable ripening conditions.

Title Alternative オオムギのアブラムシ抵抗性とグラミン:EDTA法による解析
FullText URL 004_001_073_078.pdf
Author Yoshida, Hideya| Tsumuki, Hisaaki| Kawada, Kazuo| Kanehisa, Katsuo|
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.

Title Alternative Influence of climatic factors on "crop situation index" of wheat and barley in Okayama prefecture
FullText URL 006_001_013_019.pdf
Author Kimura, Kazuyoshi| Tanakamaru, Shigemi|
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.

Title Alternative Oviposition Factors of Ponticulothrips diospyrosi on Persimmon Seedling Leaves
FullText URL 004_001_067_071.pdf
Author Uchiyama, Keiji| Kawada, Kazuo| Tsumuki, Hisaaki| Kanehisa, Katsuo|
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.

Title Alternative Relationship between Resistance to Cereal Aphids and Gramine Concentration in Beer Barley
FullText URL 004_001_043_048.pdf
Author Tsumuki, Hisaaki| Kasahara, Toshihiko| Kanehisa, Katsuo| Saeid, Moharramipour|
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.

Title Alternative Production of Strain of Erysiphe graminis f. sp. tritici That Are Pathogenic on Barley and Agropyron
FullText URL 004_002_229_237.pdf
Author Heta, Hideo| Inouye, Narinobu|
Abstract Two isolates of Erysiphe graminis f. sp. tritici, T3 and T4, were crossed and selected for pathogenicity. The corssing and selection process were repeated five times with the progenies. Isolates of each generation were inoculated on the non-hosts, Hordeum vulgare and Agropyron tsukushiense var. transiens OHWI, and parasitism and pathogenicity were investigated with respect to host specificity.As shown in Tables 2 to 5, the process of crossing and selection produced isolates which were pathogenic on barley cultivars, 'Kagoshimahadaka' or 'Russian 9' or Agropyron tsukushiense ecotypes 'Agropyron Early ecotype' or 'Agropyron Yezoense 3'.Factors affecting the degree of pathogenicity appear to be under polygenic control. The cumulative effect of minor genes may play a role in the differentiation of formae speciales suggesting a new concept of pathogenicity in the powdery mildew of grasses.

Abstract Seven hundred and thirty varieties of soybean from different sources were evaluated for seed flooding tolerance by the seed germination test after a 4-day soaking at 25℃. The inheritance of seed flooding tolerance was also analyzed with a 6 x diallel cross. A large variation in seed flooding tolerance existed in the soybean germplasm as reflected in the germination rate which ranged from 0 to 100%. Most of the varieties tested were sensitive to seed flooding, and only 4% of the tested varieties showed a high tolerance (germination rate >90%). Seed flooding tolerance was controlled by both additive and dominance genes and a small number of effective factors and high narrow sense heritability in diallel analysis indicate that the selection for tolerance can effectively be done in early generations.

Title Alternative カクヤリグサ科一年生雑草における数量分類学的研究
FullText URL 002_001_123_134.pdf
Author Muhamad Ahmad, Chozin| Satou, Kazuhiro| Yasuda, Shozo|
Abstract Three species of Cyperaceous weeds, Cyperus iria (12 strains), C. microiria(12 strains) and C. amuricus (6 strains), were collected from different sites of Okayama, Tottori and Tokyo prefectures, and various morphological characters, biomass and seed production were observed on the plants which were cultivated at Kurashiki. The analysis of variance showed a significant difference among the strains in each character. However, the species overlapped with each other in most morphological characters. Prinipal component analysis on the 21 characters showed that 83% of the total variation could be explained by the first three components: the first component (37%) was regarded as factors concerning spikelet and seed production; the second component (28%) was regarded as factors concerned the size of vegetative parts; the third component (18%) was largely affected by seed weight and floret density. Scatter diagram on the first and third principal components showed that the 30 strains of three species divided into three groups, and strains in each group correspond to the three species without exception. Based on the second and third principal components, strains of C. microiria were further divided into three sub-groups according to size of vegetative parts. Using the cluster analysis, 30 strains of these species were divided into four large clusters; the first was composed of C. amuricus strains, the second was of three strains of C. microiria, the third included the remaining strains of C. microiria, and the last cluster was composed of C. iria strains. It may be concluded that C. microiria is composed of two or three ecotypes which are different in morphological and reproductive traits.

Title Alternative Comparison of Resistance to Powdery Mildew between Wild Barley (Hordeum spontaneum C. Koch)
FullText URL 002_001_111_122.pdf
Author Fukuyama, Toshinori| Heta, Hideo| Sato, Kazuhiro| Takeda, Kazuyoshi|
Abstract A total of 162 strains of wild barley, Hordeum spontaneum C. Koch originating from Iran, Iraq, Turkey and Central Asia, were tested for resistance to powdery mildew. Then, the variation of resistance was compared with that of 145 local varieties of cultivated barley (Hordeum vulgare L.) originating from the same region of the wild barley collection. Ten different isolates of the parasite with Japanese origin were separately inoculated onto the first leaves of the host plants. The infection types were classified into the following: i, immunelike; R, highly resistant; M, moderately resistant; and S, highly susceptible. Resistant strains with i, R or M infection type were more frequent among wild barleys as compared with the cultivated forms. It is noteworthy that among these three resistant reactions,the M type was most frequent in the wild barley. To compare the degree of resistance to a total of 10 isolates, the resistance score was calculated in each of the wild and cultivated strains as the following: Scores 1,2,3 and 4 were given to the infection types of i, R, M and S, respectively, and the mean score for 10 isolates was calculated. Wild barley showed significantly low resistance scores as compared with those of cultivated barley. This was also confirmed by the cluster analysis; the cluster with more resistance to 10 isolates consisted of many strains of wild barley. Next, the resistance of wild barley was characterized by their broader effective ranges to different isolates. According to the x2 test for independence of reactions to two different isolates, the resistant factor(s) involved in wild barley was confirmed to be rather non-specific to the parasite. It was concluded that H. spontaneum may be useful genetic resources for the breeding of resistance to powdery mildew as well as local varieties.

Title Alternative Varietal Variation of Earliness in a Narrow Sense and Its Significance for Adaptation in Barley
FullText URL 002_001_023_032.pdf
Author Okubo, Kazuo| Yasuda, Shozo| Takeda, Kazuyoshi|
Abstract Heading time of is a complex character, which is controlled by several internal factors, namely, vernalization requirement, photoperiodic response and earliness in a narrow sense (ENS). The ecological significance of vernalization requirement and photoperiodic response has been clarified. However, the significance of ENS is not explained well. In this study, we examined the varietal variation of ENS, its geographical distribution and significance of ENS for regional adaptability in barley. The ENS was estimated from the number of days from sowing to flag-leaf emergence of sufficiently vernalized plants grown under a 24-h. photoperiod at 20℃ condition. The variation of ENS was determined from the number of leaves and leaf emergence intervals under the controlled condition. The ENS of 1,017 barley varieties ranged from 12 to 28 days. ENS was shortest in varieties from low-latitudes, while it was longer in varieties from high-latitudes and very low-latitudes. Multiple regression analysis for heading time(Y) on the ENS(X1) and the photoperiodic response(X2) was carried out using various data obtained from different experiment sites and sowing times. The multiple correlation was highly significant in all cases. It was clear that the ENS played an important role for determining heading time in the spring-sown conditions, while the photoperiodic response did in the fall-sown condition.

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。

Title Alternative Field Tests of Measuring System of Vegetation Response to Environmennt in a Barley Field
FullText URL 001_002_137_146.pdf
Author Maitani, Toshihiko| Kashiwagi, Yoshiaki|
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.

Title Alternative Changes of Gramine Contents as an Aphid Resistant Substance with Barley Growth
FullText URL 001_002_105_112.pdf

Abstract Barley plants may be severely damaged by aphids,mainly because they may transmit viruses,suck food and disrupt tissues. There are resistant lines and susceptible lines in barley to aphids. The changing amounts of gramine from seeding to mature stages were investigated on 27 lines from 1989 to 1991. Barley was sown aound November 20 in the year and harvested in early June. Higher amount of gramine in seeding stage in all lines were detected,then gradually decreased with barley growth until 2 to 3 weeks before the earing stages. At this time aphids had appeared on the barley leaves and increased in population. The susceptible lines had a tendency of greater decrease in gramine content than the resistant lines at the time of aphid population growth. The maximum aphid population was observed from the end of April to early May. The gramine content was almost constant this time. The degradation mechanisms may be important factors determining the defference of resistant and susceptible lines at the aphid population growth stage. The susceptible lines may have a higher activity of degradation mechanism.
