| 摘 要： | 以地王2号菜豆为试材,采用盆栽试验,测定了不同镉硫交互处理下菜豆幼苗叶片中谷胱甘肽、络合素含量等生理指标及DNA增色效应。结果表明:随着镉处理浓度的增加,菜豆幼苗叶片中丙二醛含量和DNA增色效应呈上升趋势,而100mg/kg硫水平处理下显著下降(P<0.05);与无硫对照相比,100mg/kg硫水平处理下菜豆生物量增幅较大;随着硫处理浓度增大,菜豆幼苗叶片中酸溶性硫醇、谷胱甘肽、络合素含量呈增加趋势;在轻度镉污染土壤中,添加硫元素在一定程度上可改善镉对菜豆的伤害。

| Abstract: | Physiological indexes such as glutathione(GSH),the phytochelatins(PCs),et al and hyperchromic effect of DNA were studied under the interactive treatment of cadmium and sulfur on seedling leaves of Phaseolus vulgaris Linn. in pot-soil culture.The results showed that the contents of MDA and hyperchromic exhibited a significant increase with the rise of treatment concentration of cadmium,but they decreased significantly after treatment simultaneously with sulfur of 100 mg/kg.Biomass of Phaseolus vulgaris Linn.... |
