| Abstract | 「田んぼの学校」は平成10年度の国土、文部、農水の3省庁合同で提唱された、環境教育の取組のことである。今年度、岡山県農林水産部耕地課が事業主体となり、そのモデル推進事業を岡山市福谷小学校で実施中。企画とその運営には福谷小PTAとボランティア団体から実行委員を構成してあたっている。私はその常任委員を務めているが、PTAと地域各位の多大な支援のもと年間12回もの多彩な開校が企画され現在までに9回実施、延べ551名の参加者を得ている。それぞれの企画は子供達と実行委員の希望で立案されたが、単なるイベントではなく参加者の自主的な活動によって成り立っている。親と子、そして地域の人々が一体となって架空の学校を育て上げており、この事例は今後の学校のあり方を考える上で大変興味深くかつ有益な活動である。 |

| Abstract | どの音楽作品にも、その背景には当該の地域の自然や文化が存在する。学校教育において、音楽の生成や表現を考え作品を総合的に理解するために、その歌が歌われた地域の気候や風土、生活習慣等の理解が必要である。それによってはじめて、その地域の人々の気持ちに近づくことができるのであり、そのような気持ちで歌を歌ったり聞いたりすることができる。そのためには教科間の連携が必要と考える。そこで本稿ではドイツの春を取り上げ、気候位置づけと古典派、ロマン派の歌曲に見られる春の表現について検討した。ドイツの5月には、太陽高度や日射量が急に増加し、冬から夏への昇温の最終段階近くに対応する。そのような春、5月をテーマとした歌曲では春に関する様々な音楽表現がみられる。その結果から、音楽表現と気候の関係を視点として音楽科と理科との連携について述べた。 |

| Abstract | 本稿は、アメリカで近年取り組み始めた品性徳目教育について、著者の子どもたちをアメリカの小学校に通わせた体験、あるアメリカの小学校で実際に用いられている校内研修用資料、一般書店で販売されている教師用手引をもとに、品性徳目教育の内容と実際の学校での運用を具体的に紹介するものである。内容的には、アメリカの道徳教育の変遷、品性徳目教育と従来の道徳教育との比較や学校での実際の運用の仕方、クラス討論の仕方に関する資料を取り上げた。アメリカの学校で行われている品性徳目教育は、学校やクラスごとに定められたものではなく、学校区全体で定められ、幼稚園から高校まで共通となっている。小学校では、毎月一つずつ取り上げて討論し、道徳的思考力を高めるだけでなく、実際に行動できるように実行力を養うことに力が入れられている。係の仕事の評価、問題行動の更生のためにも品性徳目がベースとなっており、児童の問題行動について保護者とコミュニケーションを取る際にも役立っていた。未来の良き市民と育成することを目標に、親切でより温かみのある、責任感ある地域社会をつくるため、地域と学校が品性徳目を要として連携し、子どもを育んでいこうとする姿が窺えた。 |

| Author | Mano, Yoshiro| Takeda, Kazuyoshi| |
| 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 | The variation in shoot regeneration obility of calli derived from immature embryos was examined in 95 wild strains, 82 of which were of Hordeum spontaneum and 13 of which were H. agriocrithon, and 87 cultivated varieties collected from various countries or regions of the world. In 85 strains of the wild species, a number of calli regenerated shoots, and their proportion ranged from 1.2% to 75.7%. The average percentage of shoot regenerating calli was 21.7% among the strains that formed calli, 11.5% of which regenerated green and 10.2% albino shoots. On average, 21.4% and 23.9% calli regenerated shoots in H. spontaneum and H. agriocrithon, respectively and there was no significant difference between these values. A significant difference in the percentage of shoot regenerating calli was found among six variants (dawense, ishnatherum, laguncliforme, paradoxon, proskowetzii, spontaneum) which were comprised in H. spontaneum. In 73 varieties of cultivated species, there were shoots regenerating calli likely to wild species, and their proportion ranged from 3.2% to 85.5%. The average percentage of shoot regenerating calli was 25.4%, 22.0% of which regenerated green and 3.4% of which regenerated albino shoots. There was a significant difference in percentage of green shoots regenerating calli against shoots regenerating ones between the wild (53.0%) and cultivated species 886.6%). The two kinds of non-brittle rachis genotypes, Bt bt2 and bt Bt2 are one of the key characters distinguishing the oriental and occidental types of cultivated barley. The average percentages of shoot regenerating calli were 16.2% and 32.3% for the genotypes Bt bt2 and bt Bt2, respectively, suggesting that there is a geographical variation in the shoot regeneration ability of calli in the cultivated species. By contrast, the oriental and occidental strains of wild species showed no difference in the shoot regeneration ability of calli. The geographical variation of shoot regeneration ability differed significantly between wild and cultivated species. This suggests that the geographical variation of shoot regeneration ability occurred after the cultivation of the barley was established. |

| Abstract | Fifteen cultures of barley powdery mildew fungus (Erysiphe graminis DC. f. sp. hordei) isolated in different regions of the world were inoculated to 120 barley varieties. Infection scores varied among the cultures and barley varieties, and their interactions were observed. Principal component analysis of the infection scores revealed that the cultures could be classified into three groups by first and second components (contributing 40.2% and 15.6% of the total variance, respectively), and that two Japanese cultures could be distinguished from the others isolated in Europe and North America. This indicates that the fungus is geographically differentiated in the reaction of the barley varieties to the cultures. Furthermore, East Asian barley varieties differed from European ones in their reactions to the culltures, while barley varieties from regions between East Asia and Europe showed a large genetic diversity in their reactions. |

| Abstract | Three viruses, Cymbidium mosaic virsu(CyMV), odontoglossum ringspot virus (ORSV) and an unidentified potyvirus were found in the orchids in Indonesia. CyMV was detected from orchids in 8 genera, namely Aranthera, Calanthe, Cattleya, Cymbidium, Gromatophyllum, Phalaenopsis,Oncidium and Vanda. The virus was widespread in many orchids in Indonesia and was common in Aranthera and Calanthe, thus being an economically important virus in Indonesia.ORSV was also detected in orchids of 5 genera, namely Bulvophyllum,Calanthe, Cattleya,Oncidium and Phalaenopsis. The unidentified potyvirus was found in Aranthera. |

| 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 | In cultivated barley, various hybrid injuries such as brittle rachis and hybrid weakness occur. Therefore, crossing must be done among cultivars to prevent the occurrence of such hybrid injuries. In the present study, we examined the magnitude of the heterosis in the crossings and geographical distribution of barley cultivars concerning heterosis. A few Japanese cultivars were used as the common parent for crossing. (1) In the six-rowed barley, 43 cultivars collected from Japan, China and Korea were crossed with non-uzu covered and naked cultivars, Shiroyo-shigara 2 and Nami-Akashinriki, respectively. The largest magnitude of heterosis in grain yield per plant was obtained in the crossing between the Korean cultivar and one of the Japanese common parents. (2) Heterosis in two-rowed cultivars was investigated using a total of 156 F1S which were cross combinations of cultivars collected from the world with two common male parents, Amagi Nijo and Kawasaigoku. The heterosis was larger larger in the cross combinations with Turkish and Ethiopian cultivars. The largest F1/BP was 1.66 in Turkish and 1.45 in Ethiopian cultivars. (3) As to uzu or semi-dwarf cultivars peculiar to Japan, 34 cultivars were crossed with two common male parents, Sekitori (covered) and Akashinriki (naked). Expression of the heterosis was rather conspicuous in the crosses of covered×naked cultivars than those of covered×covered and naked×naked ones. (4) Half diallel analysis using 10 two-rowed cultivars showed that one Ethiopian cultivar expressed a high grade of general combining ability and that one French cultivar was of higher specific combining ability. (5) The most effective agronomic character of the two-rowed cultivars to the grain yield per piant was number of ears in an ordinary year, while in the wet year it was 1000 grain weight. This was considered to be due to overluxuriant growth accompanied by lowering of the percentage of ripened grain. However, in some cultivars the percentage of ripened grain was not lowered under the overluxuriant growth condition. |

| Abstract | 大麦網斑病は糸状菌の1種であるPyrenophora teres Drechs.の感染によって葉身、葉鞘等に網目状の病斑を生じ、子実の登熟低下によって減収する共に、ビールオオムギにおいては醸造品質であるエキス分が低下する重要病害である。本病害は世界各地のオオムギ栽培地帯のうち主として温暖・湿潤な地域に分布しており（Shipton et al.1973）、近年、連作や灌漑によって被害が増大しつつある（Mathre 1982）。我国においては従来からその存在が確認されていたものの、登熟後期の活性の衰えた葉に生じる病害として重要性は認識されていなかった。しかし、最近、北海道、鳥取県、鹿児島県などのビールオオムギ栽培地帯で局所的な激発事例が確認されている。（佐藤、未発表）。本病害に対する防除法としては種子消毒ならびに殺菌剤の茎葉撒布が有効であるが、その効果は完全ではない。また、茎葉撒布はコストが高く、環境汚染の問題もあるので、最も有効で経済的かつ安全な防除法は抵抗性品種を栽培することと言っても良い。従来、本病害の積極的な抵抗性育種は行われていなかったが、最近は抵抗性を有する品種も育成されている（Metcalfe 1987）。抵抗性品種を育成するためには、遺伝資源ならびに雑種後代を効率よく評価、選抜するための検定方法を確立しなければならない。本病抵抗性の検定方法としては幼苗検定法、圃場検定法が考案されて広く用いられているが（Buchannon and McDonald 1965, Holtmeyer and Webster 1981）、環境条件の変化によって抵抗性が変動する事例が報告されているので（Khan and Boyd 1970, Tekauz 1986）、抵抗性を確実に評価するための安定した検定条件を設定する必要がある。抵抗性に関する遺伝資源についてはSchaller and Wiebe （1952）、Dessouki et al.（1965）およびBuchannon and McDonald （1965）等がそれぞれ数千品種を評価し、中国東北部、トルコおよびエチオピアなどに抵抗性の遺伝資源が豊富であること報告している。それらの品種のいくつかについては、抵抗性の遺伝子分析が行われており（Bockelman et al. 1977, Davis et al. 1990）、本病抵抗性育種の交配親として使用されている（Tekazu and Buchannon 1977, Moseman and Smith 1985）。岡山大学資源生物科学研究所大麦系統保存施設は世界的にも貴重なと東アジアの遺伝資源をはじめ五千余の保存品種を有するが、著者らは大麦網斑病の幼苗検定法を確立し、これらの品種の抵抗性を評価したので報告する。 |

| 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 Japan, wheat is usually cultivated from December to June as a second crop in the same field as rice. In Cd-polluted areas, the fields are affected by both wastewater and the emissions from the chimneys of zinc refineries or plating factories. The application of inhibition agents, such as slaked lime, calcium silicate or fused magnesium are applied to inhibit the absorption of these metals by plants. Many reports have been made on the decrease of metal absorption through the application of some form of calcium, phosphate or silicate. Also, it has been reported that wheat is more sensitive to CdS than to CdO. However, almost all experiments were performed at less than 500 ppm Cd in soil, and these experiments have not been made at a concentration close to the level critical for wheat plants. There have been few reports on the effects of calcium cabonate on metal tolerance or metal uptake at the a level critical wheat. The typical example of using calcium carbonate was investigated by Maeda, and the application of phosphate by Koshino, and by Muramoto et al. The effects of calcium carbonate on the metal content of wheat to the critical levels were examined. |
