Description |
The investigations were done to find out the suitable seed priming and foliar spray treatments for rice varieties to improve the germination under saline - sodic soil condition. The study revealed that the rice varieties of salt tolerant (TNAU Rice TRY 3), salt sensitive (ADT (R) 49) and moderately salt tolerant (CO 43) varieties given with seed priming and foliar spray treatments with hydrogen peroxide (0.25%), jasmonic acid (75 µM) and sodium nitroprusside (80 µM) enhanced the field emergence, root length, root volume, proline content and defence enzymes viz., peroxidase and catalase activity in all the varieties. Among the treatments, seed priming and foliar spray with SNP @ 80 µM recorded maximum field emergence (94%), root length (9.5 cm), root volume (1.20 cc seedling-1), proline content (449.7 µg g-1) and enzyme activity of catalase (2.83 Min g-1 ) and peroxidise (3.05 Min g-1) than the other treatments in salt sensitive variety (ADT (R) 49) indicated the suitability of the treatment for enhancing the performance of rice varieties under salt stress condition.
