Abstract: Effects of Cd on growth and some physiological characteristics of wheat seedling were studied.The results showed that the content of chlorophyll was up to the high point at 0.25 mg稬-1 of Cd concentration in the solution and decreased afterwards.The activities of SOD and POD,MDA content and permeability of membrane increased with the increasing Cd concentration.The root activity increased first and decreased afterwards.The growth of wheat was inhibited under Cd stress.The higher the concentration of Cd in solution was the more serious the inhibition was.
