| 摘 要： | 用不同浓度NaCl和等渗PEG（分子量为6000）处理四种盐生植物种子，通过对某些生理指标的测定，结果表明：NaCl和等渗PEG对种子的萌发都产生抑制作用，且PEG的抑制程度大于等渗NaCl，这说明渗透胁迫是影响盐生植物种子萌发的主要因素。在盐胁迫条件下，还用外源GA3对种子进行处理，发现GA3能缓解盐对盐生植物种子萌发的抑制。

| Abstract: | Four species of halophytic seeds were treated with NaCl solutions of different concentration and iso-osmotic PEG solutions.According to test the germination rate,germination index,We can conclude that:NaCl and iso-osmotic PEG had inhibitory effect on the germination of four halophytic seeds,and the inhibitory level of PEG were greater than that of iso-osmotic NaCl.These indicate that the osmotic stress is the main factor which affect germination of halophytic seeds.On the condition of salt stress plus GA 3 (10mg/L),the results shown that GA 3 can lysis the inhibition of NaCl on the germination of seeds. |
