Effects of Copper on Germination and Seedling Growth of Radish (Raphanus sativus L.)

Abstract

An attempt has been made to assess the response of radish under the influence of copper with special reference to seed germination and seedling growth. Copper was applied in the form of copper-chloride (CdCl 2 2.4 H 2 O). Various concentrations of copper (0, 5, 10, 25, 50, 75 and 100mg/l) were prepared and used for germination studies. It is evident from the results obtained that the increase in copper 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.
