【Abstract】 The field experiments were conducted using three rice combinations with different panicle traits. The results showed that the higher the non structural carbohydrate (NSC) of the stem and sheath at flowering stage and the lower at mature stage, the higher the seed setting rate was. The higher the average of each spikelet owning NSC at flowering stage, the higher 1000 grain weight was.更多还原
