Effect of Cadmium on the Redox System of Root Plasma Membrane in Pakchoi

doi:10.3321/j.issn:1000-7091.2007.03.015

Abstract

Abstract: The redox system existed in root plasma membrane of pakchoi. 1 mg/L Cd significantly increased the oxidation rate of NADH, and had no effects on the reduction rates of Fe(CN)₆^3- and EDTA-Fe³⁺ of plasma membrane in roots of two pakchoi cultivars. 10 mg/L decreased the oxidation rate of NADH, the reduction rates of Fe(CN)₆^3- and EDTA-Fe³⁺ of plasma membrane in roots of two pakchoi cultivars. The oxidation rate of NADPH had different tendency between two cultivars in presence of Cd.

Key words: Cadmium, Pakchoi, Root plasma membrane, Redox system
