    Japanese,

    Poor seedling establishment is a major problem for Early-Winter Direct-Sowing cultivation in rice. We examined the effects of seed coating with three materials (iron, calcium peroxide, starch) on the seedling establishment. The seedling establishment rate was only 1～3% in the control without seed coating in both 2016/2017 and 2017/2018 seasons in Iwate Prefecture. Only the coating with iron showed a significant increase in the seedling establishment rate, that is, 24% in the 2016/2017 season and 11～30% in the 2017/2018 season. Significant improvement of seedling establishment by seed coating with iron was confirmed similarly in additional four Prefectures (Hokkaido, Aomori, Akita and Mie) in 2017/2018 season. We concluded that the seed coating with iron is a promising methodology for improving seedling establishment for Early-Winter Direct-Sowing cultivation in rice.

    Japanese, Research institution, 佐賀県唐津市上場地域において、健康によい高品質農産物の開発導入を図るため、ヒヨコマメの栽培を試みた。インドにある国際半乾燥熱帯作物研究所（ICRISAT）より導入したヒヨコマメ10系統を供試し、北部九州の福岡市および佐賀県西部上場地域において2004年および2005年に栽培した。播種は2004年5月26日、8月13日および2005年3月11日に行った。収穫は2004年5月播種では8月5日、2005年3月播種では6月27日に行ったが、2004年8月13日播種では出芽直後の連続降雨の影響で立ち枯れてしまったためできなかった。子実収量は系統によって大きく変異し、両年平均で10a当り45-117kgであり、うち4系統が100kgを超えた。子実収量は栄養成長期間の長短とは相関関係がなく、百粒重および茎重とは有意な正の相関関係がみられたことから、大粒で生育期間が短い品種を選ぶことにより、北部九州においても間作として取り入れることが可能であると考えられた。しかしながら、ヒヨコマメは耐湿性に弱いため多雨な場合は、立ち枯れが多く発生し、排水のよい圃場、あるいはハウス内での栽培に適応するのではないかと考えられた。

    植物の生活史には一年生、二年生、冬型一年生、多年生などがある。冬型一年生および二年生植物は、本来、夏に発芽し越冬した翌年に急激な花茎伸長（抽台）を伴う開花、種子形成を行う。よって、子孫を残す上で夏から秋の栄養成長期間中の抽台はご法度である。しかし、上記の植物が生活環を完結させるために必須な『抽台抑制』に関しては、その抑制機構の詳細が明らかでない。よって、低分子量の生理活性物質の関与を想定し研究を進めている。本研究での実施の項目は【A】ABCの葉部から茎頂部への移動、【B】植物に存在するABC関連物質の探索、【C】ABCを受容するタンパク質とその機能、【D】シロイヌナズナ抽台誘導に関与する、ABC分解酵素をコードする遺伝子の探索、【E】早抽性および晩抽性ビートにおける遺伝子特性、【F】実農業で利用可能な、栄養成長期の抽台を抑制する植物化学調節剤の開発である。項目Aについては候補の化合物の合成に成功し、ラベルパターンの異なる化合物の合成に必要な合成方法を考案しているところである。項目Bについては、関連の化合物の単離精製、構造決定に成功し、英字の論文とした。項目Cについては、候補タンパクを釣り上げるための化合物の合成を進めている。項目D、Eについてはシロイヌナズナから選られたRNAseqデータをビートに当てはめ、相応の遺伝子を見つけつつある。項目Fについて昨年とほぼ同様な圃場実験を進めているが改良法が望まれるデータであった。

    It is thought that the energy reserving on the earth are limited, and the effective utilization of unutilized biomass resources will help sustain the human race. From the viewpoint of effective utilization of these resources, many agricultural materials originated from the unutilized biomass resources are commercially available and in use. However, their use is limited to a few events due to a lack of evidence supported by academic support. One example of unutilized biomass produced in large quantities is by-products originated from brewing processes such as beer, sake, grape wine, and shochu. In this project, we focus on the seed residue from wine brewing and report that it is a promising material for increasing the yield of potatoes. The results of this research will serve as a model case study for the construction of a resource-recycling society.

    Potato plants are week for drought stress because of its small root mass and less extension to deep soil layers. To enhance the improvement of root system in potato breeding, we examined the difference in root mass in a diploid CxE population introduced from the Netherlands and detected a effective QTL for root mass at Chromosome 5. The root mass showed highly correlations with plant earliness and early tuber bulking, of which QTLs were located at the same position of root QTL.

    The objective of this study was to estimate the plant water stress in the community, not in a single plant only, via the transpiration status in wheat.
    As the plant canopy temperature reflects the transpiration status, it was estimated by using an infrared thermograph in several wheat genotypes developed in Syria and Japan. The canopy temperature of a Japanese genotype which had the smallest seed yield show the highest between the 35 and 57 days after sowing. This indicates that this genotype would suffer from plant water stress during this period, which might result in the largest yield loss through preventing proper panicle development. This study showed the usefulness of infrared thermograph to capture the genotypic differences on canopy temperature in wheat.
