摘要
重金属在自然环境中很难被降解,环境中的重金属污染往往会影响到植物的生长、发育以及种子的萌发。国内外很多学者和专家在重金属对种子萌发生长影响等方面进行了大量的试验研究,虽然其中一些重金属在低浓度时对某些种子的萌发有促进作用,但是基本上所有的重金属在超过一定的浓度范围后都抑制种子的萌发,为此就国内外关于Hg、Pb、Cd和Cr等重金属在影响种子萌发方面所做的研究进行了综述。
Heavy metals are difficult to be decomposed under natural environment , those heavy metals must take some negative effect to environment and ecosystem, a lot of domestic and international scholars have made a large number of experiment research about the influence of heavy metals to seed germination . Many results suggested that when at low density some heavy metals may be accelerate seed germination , but when exceeding certain density range nearly all heavy metals inhibit seed germination. In this paper, a summary has been done about heavy metals such as Hg,Pb,Cd,and Cr influence seed germination domestic and internationally.
