种子大小对冬小麦繁殖体及产量的影响

Effect of Seed Size on the Reproductive Body and Yield in Winter Wheat

采用大、小粒种子分别单种和大、小粒种子混合种植进行盆栽试验。研究表明：大粒种子形成的繁殖体较大，等级差异较小，产量较高；小粒种子形成的繁殖体较小，等级差异较大，产量较低；大小粒混值群的繁殖体其大小和差异变化不一，产量居中。

Potculture experiment was conducted by individual planting large, small and mixed seeds respectively. This study showed that: Compared with the reproductive body from small seeds, the reproductive body from large seeds was larger. the hierarchy difference was smaller and grain yield was higher. Meanwhile, the size and hierarchy difference of the reproductive body from mixed seeds was variant, grain yield was mediate.
