Impact of Cadmium on Germination and Seedling Growth of Carrot (Daucus Carota)

Abstract

An attempt has ben made to assess the response of carrot under the influence of cadmium with special reference to seed germination and seedling growth. Cadmium was applied in the for of cadmium-chloride (CdCl22.5H2O). Various concentrations of cadmium (00.5,10,25,50,75 and 100 mg/l) were prepared and used for germination studies. It is evident from the results obtained that the increase in cadmium concentration affected all the growth parameters, such as germination percentage, length of root and shoot, fresh weight of root and shoot, vigour index and tolerance index
