通过不同浓度NaCl胁迫对小麦发芽的影响的研究表明 ,NaCl对种子萌发的影响表现在离子伤害和渗透胁迫 2个方面 ,NaCl对发芽期幼苗生长的影响主要是抑制其根、芽的生长 ,其中受抑制最强的是根的生长速度 ,芽的生长速度次之 ,对根数的影响最小 ;不同品种受NaCl胁迫的程度不同 The results showed that the effects of NaCl on the seed germination were affected by ion damage and osmotic stress. The effects of NaCl on the growth of seedling at the germination stage were mainly inhibited by the growth of roots and shoots, in which The strongest inhibition was the growth rate of roots, followed by the bud growth rate, and had the least effect on the number of roots. Different varieties were different in the degree of NaCl stress
