摘　　要：本文研究了细绿萍对不同浓度的铅和汞在生长发育和生理等方面作出的反应。结果表明,一定浓度的铅和汞不仅能抑制细绿萍的生长和发育,且能使其中的叶绿素含量下降,并对可溶性蛋白的含量也有一定的影响。This paper is to study the response of Azolla filiculoides Lamk in growth and physiology to different concentration of Pb and Hg. The results show, with increasing metal concentration, the growth of Azolla is inhibited, the content of chlorophyll decreases and the soluble proteins are affected in some degrees.
