Effects of Fertilizer and Sulfate Treatment on Phytochelatins Content in Zizania latifolia under Cadmium Stress
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.
