| 摘 要： | 以单季茭品种蒋墅茭和双季茭品种葑红早为试材，土壤为栽培介质，对100 mg?L-1 Cd2+胁迫进行不同肥料和不同浓度的硫处理，研究了茭白根系和叶片中的非蛋白巯基、谷胱甘肽及植物络合素含量变化。结果表明：供硫能促进茭白根系和叶片中非蛋白巯基、谷胱甘肽及植物络合素含量的增加，能增强茭白对镉胁迫的抗性；无机肥（三元复合肥）处理的谷胱甘肽、植物络合素含量高于有机肥（菜籽饼）处理；根系中的非蛋白巯基、谷胱甘肽及植物络合素含量显著高于叶片；品种间则以蒋墅茭高于葑红早。

| Abstract: | Content of non-protein-thiols（NPT）, glutathione（GSH）and phytochelatins（PCs）in leaves and roots of Zizania latifolia were studied on single-harvested cultivar‘Jiangshujiao’and double-harvested cultivar‘Fenghongzao’. These 2 cultivars were cultured in soil with organic fertilizer（OF）and inorganic fertilizer（IF）at different concentrations of sulfate treatment under 100 mg?L-1 Cd2+ stree. The results showed that content of NPT, GSH and PCs in Zizania latifolia leaves and roots were increased when treated with sulfate under cadmium stree. Content of GSH and PCs were higher when treated with IF than OF. These contents in Zizania latifolia roots were remarkably higher than in leaves. Contents of NPT, GSH and PCs of‘Jiangshujiao’were higher than that of‘Fenghongzao’in leaves and roots at the same treatment. |
