Toxicity of cadmium on the growth and yield of Solanum melongena L.
Heavy metal cadmium is biomagnified through food chain and causes Itai-Itai disease in human. The present investigation reports the results of the effect of cadmium on seed germination, germination relative index (G.R.I.), seedling growth, chlorophyll stability index (CSI) and yield of Solanum melongena L. cv Pusa uttam. Effect of different concentrations of heavy metal cadmium (CdCl2) in Hoagland's nutrient solution (10(-2) M, 10(-4) M, 10(-5) M and 10(-8) M) were employed for all seedling and physiological parameters of brinjal. Cadmium showed toxic effects at high concentrations 10(-2) M but promotory at lower concentration (10(-8) M) with regard to growth and yield.
