为解决苜蓿种子萌发的盐害问题，采用不同浓度壳聚糖溶液（50～250 mmol／L）对苜蓿进行浸种处理，在100 mmol／L NaCl 胁迫下进行苜蓿种子的萌发试验。结果表明：与清水对照相比，盐胁迫显著抑制苜蓿种子的萌发，壳聚糖50～200 mmol／L 溶液浸种处理后，盐胁迫苜蓿种子的萌发效果均有不同程度升高，其中以150 mg／L 壳聚糖处理对盐胁迫下苜蓿种子萌发的缓解效果最好，其根长、活力指数、苗高、发芽指数、发芽势和发芽率分别比盐胁迫对照组高7．82倍、52．27％、47．92％、22．68％、16．28％和15．67％。

In order to solve problem of salt injury in germination of M.sativa seeds,the effects of seeds soaking in chitosan solutions with different concentrations (50 ~ 250 mmol/L ) on germination characteristics of the seeds of M.sativa under 100 mmol/L NaCl stress were studied.Results:The seed growth of M.sativa under salt stress were obviously inhibited compared with the control (water).The seed germination indexes were improved in different extent after 50~200 mmol/L chitosan treatment,the treatment in 150 mmol/L chitosan could get the best relieving effect,the values of root length,vigor index,seedling length,germination index,germination energy,and germination percentage of the seeds in 150 mmol/L Chitosan improved 7.82 times,52.27%,47.92%,22.68%,16.28% and 15.67% higher than in the salt stress treatment respectively.
