Air Quality Status and its Impact on Nitrate Reductase, Superoxide Dismutase and Peroxidase Activities of Plants in Lime Kiln Area

Study of impact of lime kiln emission on enzymtic parameters like nitrate reductase, superoxide dismutase and peroxidase in Syzygium cumini, Mangifera indica, Citrus limon, Ziziphus mauritiana, Psidium guajava, Artocarpus heterophyllus, Pongamia pinnata, Acacia nilotica, Dalbergia sissoo, Azadirachta indica, Eucalyptus hybrid and Butea monosperma, revealed significant variation in their quantities. These enzymatic variations can be used for early diagnosis of stress or as a marker for physiological damage to trees even at low pollution levels, prior to the onset of visible injury symptoms.
