摘　　要：试供品种为中粳杂交稻 80优 12 1。设剪叶、疏花处理 ,研究其库源与结实率的关系 ,结果表明 :(1)光合叶面积是影响结实率的主要因素 ;(2 )增加库容量可导致结实率下降 ;(3) 80优 12 1库源关系可归纳为源限制型 (增源增产型 )。The relations between source-sink and seed setting rate of the hybrid rice 80 you121 was studied by means of leaf-cutting and spikelet-thining The results showed that:1. Seed setting rate was affected mainly by the area of leaf Photosynthesis;2. Seed setting rate was down by increasing sink size;3. 80 you 121 belongs to the type of Source-limitation
