Pesticide induced alterations in physiological responses in Camellia Sinensis

Treatment with monocrotophus (pesticide) for four days to tea (Camellia sinensis (L) O. Kuntze) seedlings showed a decrease in chlorophyll content, carotenoid content and peroxide content with an increase in thiobarbituric acid reactive substance (TBARS), a measures of lipid peroxidation. Though superoxide dismutase (SOD) and glutathione content increased but activities of catalase (CAT), peroxidase (POX), glutathione reductase (GR) and ascorbate content decreased in pesticide treated plants as compared to control.
