不同粒度的小麦种子在活力、植株生长发育及产量方面存在明显差异.大而饱满的种子活力大、生长优势强、产量高.千粒重40.1克的一级种子,其产量明显高于其它三级种子(千粒重分别为32、21.6和13.9克),经显著性测验,一级种子与三级种子产量差值为32.77斤/亩,达到显著水平;与二级种子产量差值为37.27斤/亩,达到极显著水平.
There were significant differences in vitality, plant growth and yield of wheat seeds with different grain sizes.The seeds of large and full seeds were strong in vitality, strong in growth and high in yield.The first seeds with a grain weight of 40.1 grams had significantly higher yield than the other third seeds (Thousand kernel weight were 32,21.6 and 13.9 g, respectively). After significant test, the difference between the first seed and the third seed was 32.77 kg / mu, reaching significant level. The difference with the second seed yield was 37.27 kg / Reached a very significant level.
