摘要
本文用测定种子发芽势的方法，对Ｃｄ２＋、Ｈｇ２＋Ａｓ３－的生物毒害效应进行了试验，结果表明，种子发芽指数能很好地反映不同浓度Ｃｄ２＋、Ｈｇ２＋、Ａｓ３－的生物毒害作用．种子发芽势试验也可用于多成分污染物的生物毒性判别，通过相关分析或复回归分析可以大致判别出多成分污染物中何种成分生物毒性大．
The methed of testing seed germinating potential was used for experiment of biologcal effect of Cd2+,Hg2+,As3-. The results showed the seed germinating indexes (SGI)could reflect biological toxic effect of Cd2+,Hg2+,As3- with different concentrations very well. SGI experiment coule also be used for biological toxic judgement of multi-fraction pollution materials as biologcial indexes. By relation analysis or multi-regretion analysis,it could be roughly judged which fraction was the most toxic one in a multy-fraction pollution material.
