两优培九穗颈节与穗部性状关系研究
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
结果表明：两优培九株叶型好，粒叶比和光合面积大，营养生长期群体干物质积累能力强，始穗后叶片功能期长、籽粒灌浆持续时间较长，抽穗期至成熟期的干物质增量明显强于其亲本和对照组合；穗颈节间维管组织比亲本及对照发达；两优培九单株总库容量大，每穗实粒数多，千粒重较大。
