| dc.description.abstract | The effect of seed treatments with proline and salicylic acid on some physiological and biochemical parameters of tinda (Citrullus vulgaris L.) cv.S-48 seeds were studied. Seeds of tinda were treated with different concentrations of proline (1mM, 5mM, 10mM and 20mM) and salicylic acid (0.1mM, 0.5mM, 1mM and 5mM) for 5 hours at 25°C and 20°C. After 12 days of germination, seedlings were collected for physiological and biochemical examination. All the seed treatments increased the physiological parameters such as percent germination, seedling length, fresh weight, dry weight, vigour index I and II and speed of germination as compared to control. The treatments decreased the electrolyte leakage as compared to control and increased biochemical parameter like total soluble sugar, proteins, activity of antioxidant enzymes like catalase, peroxidase and superoxide dismutase as compared to control at both the temperatures. Hydration and warm water treatments also increased different physiological and biochemical parameters. Proline 20mM was more effective than proline (1, 5 and 10 mM). Similarly, salicylic acid 1mM was effective maximally among salicylic acid concentrations (0.1, 0.5 and 5 mM) at both the temperatures. | en_US |
