Sub-cellular Fraction of Heavy Metals and Production of Phytochelatins in Zizania latifolia Exposed to Cadmium and Lead
复合胁迫下茭白体内镉、铅的亚细胞分布和植物络合素的合成

A single-harvested cultivar,'Jiangshujiao',and a double-harvested cultivar,'Fenghongzao',of Zizania latifolia were used as experimental materials to determine the content of non-protein-thiols(NPT),glutathione(GSH),and phytochelatins(PCs).To clarify the tolerance mechanism of Zizania latifolia to Cd2+ and Pb2+ stress,accumulation of Cd2+ and Pb2+ in subcellular fractions were also investigated.The results showed that content of NPT,GSH,and PCs and the accumulation of Cd2+ and Pb2+ in subcellular fractions i...
