Response of antioxidant enzymes to transfer from elevated carbon dioxide to air and ozone fumigation, in the leaves and roots of wild-type and a catalase-deficient mutant of barley
A catalase-deficient mutant (RPr 79/4) and the wild-type (cv. Maris Mink) barley (Hordeum vu/gare L.) counterpart, were grown for 3 weeks in high CO 2 (0.7%) and then transferred to air and ozoneExpand
