低浓度水扬酸浸种可促进水稻种子萌发和种子根、芽的生长 ,增强种子根、芽的呼吸速率和根系活力 ,提高幼苗含水量、可溶性糖和可溶性蛋白质的含量 ,降低膜相对透性 ,且浓度越低 ,效果越显著 ;而高浓度的水扬酸则抑制了水稻种子萌发。
Soaking seeds with low concentration of salicylic acid could promote the seed germination, the growth of seed roots and shoots, enhance the respiration rate and root vigor of seed roots and shoots, increase the content of water content, soluble sugar and soluble protein in seedling, lower the relative permeability of the membrane, And the lower the concentration, the more obvious the effect; while the high concentration of salicylic acid inhibited rice seed germination.
