摘　　要：主要研究铅胁迫对芜荽种子萌发、幼苗生长、叶绿素含量、还原糖、总糖、可溶性蛋白和超氧化物歧化酶(SOD)、过氧化物酶(POD)活性等的影响,初步探讨铅胁迫对芜荽的毒害机理。可为预防重金属对农作物的毒害、提高污染土壤上植物生长的安全性和环境监测中对重金属污染的评价提供一定的依据。Mainly research the impact of different concentrations of lead stress on Raphanus sativus seed germination,seedling growth,leaf chlorophyll content,soluble protein content,reducing sugar content,total sugar content,superoxide dismutas（SOD） activity,peroxidase（POD） activity and total antioxidant capacity（T-AOC） in this paper. Preliminary discuss the poisoning mechanism of lead stress to Raphanus sativus. These will provide some basis for prevent the poison of heavy mental to crops,improve the safety of plant grows on the contaminated soil and evaluate the pollution of heavy metal in the environmental monitoring.
