水分是种子发芽的重要生态因子，发芽床的含水量是种子发芽试验标准化的基础。本试验通过对12种不同梯度水分含量影响棉花种子发芽率和发芽势的分析，得出脱绒棉籽发芽的最适含水量在10～14ml／100g范围。
Water is an important ecological factor of seed germination, germination bed water content is the standard seed germination test basis. Based on the analysis of the effects of 12 different gradient moisture contents on the germination rate and germination potential of cotton seeds, the optimum water content of the de-cottonseed is 10 ~ 14ml / 100g.
