Comparatively study on morphological characters and physiological activity of the upmost internode in high - yield hybrid rice during ripening phase
兩優培九穗頸節與穗部性狀關系研究The characteristics of vascular bundle in the first internode and grain - filling of heavy panicle hybrid rice ( hphr ) were studied
摘要對重穗型雜交稻穗頸節間維管束特徵及其籽粒充實進行了研究。The results indicated that liangyoupeijiu showed better plant and leaf type, higher ratio of grains to leaf area and larger photosynthesis area, stronger ability of population dry matter accumulation during the period of vegetative growth especially from heading to being mature, longer leaf duration and grains - filling after heading than that of its parents and controls s ; more grains per panicle, lager all sink per plant and 1000 - grain weight
結果表明：兩優培九株葉型好，粒葉比和光合面積大，營養生長期群體干物質積累能力強，始穗后葉片功能期長、籽粒灌漿持續時間較長，抽穗期至成熟期的干物質增量明顯強于其親本和對照組合；穗頸節間維管組織比親本及對照發達；兩優培九單株總庫容量大，每穗實粒數多，千粒重較大。
