盐胁迫对不同品种小麦种子萌发的影响

Effect of Salt Stress on Seed Germination of Different Wheat Varieties

研究了NaC1胁迫对4个小麦品种种子发芽的影响.结果表明,低盐浓度对小麦种子萌发有促进作用,随着NaC1胁迫浓度的增大,对种子萌发的抑制作用明显增强,在供试的4个小麦品种中,不同品种小麦种子萌发受盐胁迫抑制的程度不同,其中"神龙4号"为耐盐品种,"神龙3号"次之,"川麦32号"耐盐性中等,"绵农7号"不耐盐.

The effects of salt stress on the seed germinations of 4 wheat varieties were studied.The results showed that lower salt concentration had a stimulating effect on germination.As NaCl concentration rose,the inhibitive effects on the seed germinations obviously increased.The seed germinations of the 4 wheat varieties were differently inhibited by the stress.＂Shenlong 4＂ was tolerant to salt and ＂Shenlong 3＂ was second to ＂Shenlong 4＂.＂Miannong 7＂ was not tolerant and ＂Chuanmai 32＂ was moderately tolerant.
