| 摘 要： | 通过水培试验,研究了在不同加硅量(0,30,60,90,120,150 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(30,60,90 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,POD,CAT),proline content,soluble protein content and MDA content of wheat seedling with different concentrations of Si(0,30,60,90,120,150 mg/L,SiO2).The results showed: At the action of Si(30,60,90 mg/L,SiO2),chlorophyll-a content,antioxidant enzymes system(SOD,POD) activity,proline content,soluble protein content of wheat seedling increased and MDA content droped... |
