1影响小麦种子质量的主要因素1.1小麦种子的后熟作用小麦种子具有明显的后熟作用和较长的后熟期,后熟期一般在60d左右,且随种植季节及品种不同而稍有差异,一般春性小麦后熟期较长,冬性小麦则较短;红皮小麦后熟期较长,白皮小麦后熟期较短。处于后熟期的小麦种子表现为呼吸强度高、酶活性大、生理代谢旺盛且发芽率低等特点;完成生理后熟作用的小麦种子发芽率将显著
1 The main factors affecting the quality of wheat seeds 1.1 The ripening effect of wheat seeds Wheat seeds have obvious after-ripening effect and long after maturity, the maturity is generally about 60d, and with the planting season and varieties vary slightly , General spring wheat later maturity, winter wheat is shorter; red wheat longer maturity, white wheat short maturity. The wheat seeds in the late ripe stage showed the characteristics of high respiration intensity, large enzyme activity, strong physiological metabolism and low germination rate; the germination rate of wheat seeds for physiological post-ripening effect would be significant
