摘要：研究不同盐浓度对马齿苋种子萌发的影响。通过不同盐浓度处理，对马齿苋种子在不同盐浓度下萌发的状况进行分析。结果表明：蒸馏水条件下种子萌发率最高,实验表明一定盐浓度可以促进马齿苋幼苗的生长，5%左右盐浓度是马齿苋幼苗生长的最适浓度，而种子萌发以无盐环境为最好。

Abstract：To study the effect of different salt concentrations on the seed germination of Portulaca. Through the different salt concentration processing, analsis the seeds of Portulaca in different concentrations of salt germination condition. The results showed that the highest seed germination rate was under the distilled water. Experimental results show that a certain salt concentration can promote the growth of the seedlings of Portulaca.About 5% of the salt concentration was Portulaca’s seedlings growth of optimal concentration.But its seed germination was suitable for no salt environment.
Key words:Portulaca;Seed germination;Different salt concentrations
