摘要： 以3个不同穗部性状类型的组合广超1号、特优明86和65396为材料进行大田试验，结果表明开花期茎鞘非结构性碳水化合物含量高，成熟期含量低的品种，结实率高，反之，结实率低。每个颖花平均从茎鞘获得非结构性碳水化合物高的品种，千粒重高。反之，千粒重低。

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.
