摘　　要：以芦苇幼苗叶片为试材,研究了Cd、Zn、Pb重金属污染5d对芦苇叶片叶绿素含量的影响。结果表明:3种重金属对芦苇叶片叶绿素含量的影响不同,Pb对叶绿素a的影响最大,Cd对叶绿素b的影响最大,但随着芦苇幼苗重金属处理时间的增长,叶片叶绿素含量呈现普遍下降的趋势。并确定叶片叶绿素含量下降可能是重金属污染对植物毒害作用之一。The changes of chlorophyll content in reed leaves were studied under heavy metal pollution treatment on reed after a certain period.The results showed that three kinds of heavy metals influences on reed leaf chlorophyll content were different,Pb had the biggest effect on chlorophyll a while Cd on chlorophyll b.However,along with the treatment time growing,the reed leaf chlorophyll content had a generally downward trend.The results also showed that the decrease of reed leaf chlorophyll content may be one of the toxic effects about heavy metal pollution on plants.
