Abstract

Abstract: Hydroponic culture was conducted to study the effect of different concentrations of cadmium stress on the growth and physiological and biochemical characteristicsof seedings of Vigna radiata L.. The results showed that the plant height and fresh weight of seedings of Vigna radiata L. were inhibited with the increase of Cd²⁺ concentration; The chlorophyll content of the leaves of seedings decreased, but malondialdehyde （MDA） content, superoxide dismutase （SOD）activities, peroxidase （POD） activities and catalase （CAT） activities gradually increased with the increase of Cd concentration,while the soluble sugar content increased at the beginning then decreased. The results indicated that the Cd²⁺ stress would destroy the biofilm function of Vigna radiata L., caused the oxidative intimidation and affected their growth and development.

Key words: Vigna radiata L., Cd²⁺ stress, seedling growth, physiological and biochemical characteristics
