摘要： 籼稻大粒型品种虽然千粒重常较一般品种高,但因结实性差,难以在生产上广泛应用。本文试图探明某些大粒型品种结实性差的生理原因。据观察试验中三个大粒型品种结实性差主要在于空谷率高。据分析这三个大粒品种小穗不育的原因,是雄性器官发育过程中活力较弱,氮、碳营养匮乏,尤其是淀粉累积缓慢,不适应花粉粒充实的需求,因而花
Abstract: It was found that the large-grain type varieties of Indica rice hadhigher grain weights and lower fertility,as compared with the commonones.The lower fertility account for the formation of numerous male ste-rile spikelets,and its physiological aspects were discussed.There were two possibilities for
