不同浓度铅处理对木本植物种子发芽的影响

摘要

This article takes Gleditsia .Sinensis Lam and Robinia pseudoacacia L .as testing objects .Through the tests of different Pb concentrations ,the article tries to find out the influences on seed germination .The results show that with the increase of Pb2+ concentration ,the germination rate of woody plant decreases .%以皂角、刺槐为试验材料，通过不同浓度铅处理，研究了其对种子萌发的影响。结果表明：随着铅离子浓度的增加，植物种子的发芽率下降。
