Popis: Effect of different seed treatments hydration, warm water, proline (10mM and 20mM) and salicylic acid (0.1mM and 0.5mM) was investigated on percent germination and activity of antioxidant enzymes viz. superoxide dismutase (SOD), catalase (CAT) and peroxidase (POX) at different temperatures in Muskmelon (Cucumis melo L.) seeds. It was observed that lower temperature (20˚C) had decreased seed germination and activity of various anti-oxidant enzymes. Various seed treatments increased percent germination and activity of these enzymes as com-pared to control at both the temperatures. Proline 20mM (96.6) and SA 0.1mM (91.6) showed better results as com-pared to proline 10mM (95.0) and salicylic acid 0.5mM (86.6) respectively. Thus, proline and salicylic acid play an ameliorating role on low temperature stress by enhancing the activities of antioxidant enzymes and scavenging the free radicals.
