摘要

通过水培试验

研究了在不同加硅量(0

120

150 mg/L

以SiO2计)作用下

铜(10 mg/L

以Cu计)对小麦幼苗叶绿素含量、抗氧化酶系统活性(SOD、POD、CAT)、脯氨酸含量、可溶性蛋白含量以及MDA含量的影响

结果表明:在加硅量(30

90 mg/L

以SiO2计)作用下

小麦幼苗叶绿素a含量、抗氧化酶系统(SOD、POD)活性、脯氨酸含量、可溶性蛋白含量的升高以及MDA含量的降低

减轻了铜对小麦幼苗的毒害作用;在加硅量150 mg/L作用下

小麦幼苗叶片可溶性蛋白含量的降低

MDA含量的升高

加重了铜对小麦幼苗的毒害作用。研究结果表明

加硅处理能够在一定浓度范围内缓解铜对小麦幼苗的毒害作用

从而为铜毒害的小麦区域增施硅肥提供理论依据。

Abstract

The water culture experiment was conducted to investigate the effects of Cu(10 mg/L)on chlorophyll content

antioxidant enzyme system activity(SOD
