It was shown that using seeds stored at 20 ℃ for 3 days after they were coated with an oxygen supplier was effective for uniform emergence and a higher emergence rate in the tested cultivars. Dry matter production at yellow-ripe stage and grain yield of the direct-seeded RWCS were lower than those of transplanted RWCS. In direct-seeding, greater dry matter production was obtained in cultivars that showed longer growth period, larger leaf area during ripening period, and lower specific leaf area, which results in high leaf-blade nitrogen content and a lower extinction coefficient. The newly developed RWCS cultivar \"Bekoaoba\" and the spikelet-decreased mutant \"RM645\" were considered more suitable for direct-seeding cultivation, because they showed higher lodging resistance in addition to these desirable characteristics in dry matter production.\n","subitem_description_type":"Abstract"},{"subitem_description":"東北地域における飼料イネ直播栽培の確立に必要な基礎データを得るために，飼料イネ向け品種・系統の直播栽培適性の評価および東北地域の直播栽培で高い乾物生産性を発揮するための生育特性について検討した。その結果，出芽については顕著な品種間差は認められなかったが，各品種ともカルパー被覆後の加温処理により苗立ちの安定化が図られた。また，乾物および玄米収量に関しては，移植栽培と比較して直播栽培では黄熟期の乾物収量および玄米収量は低かったが，生育期間の確保が可能な晩生品種が乾物生産の増大に有利であることが確認された。さらに，直播栽培において乾物生産を高める形質として，出穂期までに高い葉面積を確保するとともに，登熟期の葉面積を高く維持することや，葉身が厚く，葉身窒素含有率も高いこと，および吸光係数が低く受光態勢に優れることなどの特性を有することが重要であると考えられた。飼料イネ向け新品種の「べこあおば」や着粒突然変異系統のRM645 はこれらの形質や耐倒伏性の安定性の点で飼料イネの直播栽培に有利な特性を示した。\n","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24514/00001192","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"独立行政法人
