摘要/Abstract

摘要： 通过盆栽实验研究了Cu、As及其复合处理对小麦生理生态指标的影响.结果表明.少量低浓度的Cu(500mg·kg^-1)、As(5mg·kg^-1)对植物的生长无明显毒害作用,但随着其浓度的增加(Cu:1000～4000mg·kg^-1,As:15～60mg·kg^-1)则显示出一定的负效应,表现为小麦POD活性增加,叶片电导率增大,色素含量降低.根尖细胞有丝分裂指数下降,小麦生物量降低;而两者的复合处理则存在一定拮抗作用.此外,研究还表明,小麦生物量与As浓度的相关性大于Cu.

Abstract: Based on the pot experiments,effects of Cu,As and their combination pollution on eco physiological index of the wheat were studied in this paper.The results showed that the low concentration of Cu (500mg·kg^-1),As (5mg·kg^-1) had no obvious effects on wheat.But as the concentration of Cu and As (Cu 1000～4000mg·kg^-1,As 15～60mg·kg^-1) increased,there existed obvious negative e ffects such as the POD activity and conductivity of wheat leaves increased,mitos is index and contents of chlorophyll decreased.There also existed antagonism bet ween Cu and As in the combination pollution.It was alsofound that the effect of As on wheat is heavier than the effect of Cu from the experiment.
