dc.description.abstractIn this work, the effect of proline and salicylic acid on physiological and biochemical parameters of muskmelon (Cucumis melo L.) seeds c.v. Punjab Sunehri at different temperatures was studied. The low temperature has deleterious effect on seed germination and seed vigour parameters. Seeds of muskmelon were treated with different treatments (hydration, warm water and different concentrations of proline and salicylic acid) at 20˚C and 25˚C. Various estimations were done from the treated seedlings after 8 days of germination. All the seed treatments increased the physiological (percent germination, seedling length, seedling biomass, speed of germination, vigour index I and II) and biochemical parameters (total soluble sugars, total soluble proteins and activities of antioxidant enzymes) of seedlings as compared to control at 20˚C and 25˚C. But as far as electrolyte leakage was concerned, different treatments were effective in decreasing the leakage of electrolytes at both the temperatures. The results showed that Proline 20mM and salicylic acid 0.1mM were more effective as compared to proline 10mM and salicylic acid 0.5mM at both the temperatures. Thus, application of proline and SA could play an ameliorating role on low temperature stress tolerance by regulating and scavenging the free radicals produced by reactive oxygen species.en_US
