春小麦种子大小对主要性状及产量的影响

通过8个春小麦品种的大、小粒种子在大田进行播种试验，结果表明：大粒种子形成的植株分蘖数多，营养生长旺盛，收获穗数多，产量较高。而在株高、穗长、单穗粒数及千粒重等性状上，种子大小不产生直接影响。

Effect of Seed Size on the Character Essentials and Yield in Spring Wheat

Culturalexperiment was conducted by planting large and small seeds of eight spring wheat cultivars respectively in the field. This study showed that compared with small seeds, tiller numbers of plant and head numbers from large was higher. There were some small or no influence directly of seed size in plant height and spike length and grain unmbers per spike and 1000-grain weight.
