Consequence of chromium-tainted soil on physical and biochemical responses of Vigna radiata L.

Abstract

Mung bean (Vigna radiata L.) is one of the important leguminous plants of India, with shorter growing season. In this work, the intention was to correlate the effects of chromium on physical and biochemical responses of V. radiata L. Mung bean seeds were germinated and grown under controlled treatment, with different concentrations of waste soil mixed with garden soil. Physical parameters such as shoot length, root length, and fresh weight were found highest in control soil and 25% of contaminated soil, whereas 50% and pure contaminated soil showed poor growth stage and poor quality physical parameters. Biochemical parameters such as total chlorophyll content, protein content, and starch content were found highest in control soil and 25% contaminated soil, but these parameters were found to be less in 50% and pure contaminated soil. It was observed that physical and chemical parameters were declining with increasing chromium contamination.
