Abstract
At different temperature (25°C and 20°C), the effect of seed treatments (proline and salicylic acid) on some physiological parameters of tinda (Citrullus vulgaris L.) cultivar S-48 seeds was studied. Tinda seeds were treated for 5 h with different concentration of proline (10 mM and 20 mM) and salicylic acid (0.5 mM and 1 mM) at 25°C and 20°C. After 12 days of germination, seedlings were used for analysis of physiological parameters. The seed treatments increased the germination percentage, vigour index I and vigour index II as compared with control at both the temperatures. Proline 20 mM was more effective than proline 10 mM. Similarly, salicylic acid 1mM was more effective than salicylic acid 0.5mM at both the temperatures 25°C and 20°C.
