| 摘 要： | 星星草（Ｐｕｃｃｉｎｅｌｌｉａｔｅｎｕｉｆｌｏｒａ）种子经不同浓度ＮａＣｌ溶液处理结果表明；与对照相比，低于０．６ｇ／１００ｍｌ的盐浓度对种子萌发有促进作用；介于０．７ｇ／１００ｍｌ—３．６ｇ／１００ｍｌ间，种子的萌发势和累积发芽率显著下降，但尚不影响其萌发潜势，解除盐分限制后，还可正常萌发；高于３．７ｇ／１００ｍｌ后，不仅抑制种子萌发，并对其萌发潜势有显著影响。

| Abstract: | Seeds of puccinellia Tenuiflora were treated with NaCI salt solution of different Concentration. The resuct showed that the seed germination was stimulated at the Concentration of under 0. 6g/100ml .The germinating energy and accumulated germination Percontage were reduced significanthy at the Coucentration of between 0.7g/100ml-3.6g/100ml, but its potenial was not affected efet. when the restviction of the salt Coucentration was removea, the seed Could still germinated regularly; seed germination and its potential restrained remarkably when the coucentration was above 3.7g/100ml. |
