Abstract :Seedlings of mung bean insert ignore into journalissuearticles values(Vigna radiata L. Wilczek); cv. T-44 grown on a sand culture were exposed to cadmium insert ignore into journalissuearticles values(Cd); insert ignore into journalissuearticles values(100 µM); on day 10 of growth. These seedlings were subsequently sprayed with deionized water insert ignore into journalissuearticles values(control); or 4-chloroindole-3-acetic acid insert ignore into journalissuearticles values(4-Cl-IAA); insert ignore into journalissuearticles values(10-6 M); on day 15 and were sampled 30 days after sowing to assess growth and metabolite content. Growth insert ignore into journalissuearticles values(length, and fresh and dry mass of roots and shoots); and the level of metabolites insert ignore into journalissuearticles values(chlorophyll, nitrogen, phosphorus, total sugar, and soluble protein); in the leaves significantly decrease in response to Cd stress; however, the 4-Cl-IAA insert ignore into journalissuearticles values(10-6 M); treatment, both in the absence and presence of Cd, significantly increased the parameters studied. The response generated in the plants grown under stress-free conditions was more prominent, as compared in those exposed to Cd.
