Seed Priming:: A Sustainable Approach to Improve Salinity Tolerance in Rice

The most consumed main dietary crop worldwide is rice, which is also a significant source of fiber, energy, minerals, vitamins, and other biomolecules. Environmental pollutants and abiotic stress influence seed germination, emergence, and agricultural output. Salinity can affect agricultural output in dry and semi-arid regions. Underneath salt conditions, seed priming has the benefit of displaying steady and faster germination price, seedling vigor, and crop development below adverse circumstances, as well as overcoming them from dormancy. The present study explored various seed priming techniques in rice varieties like Mallikuruva and Mattathriveni to standardize suitable treatment and to examine its effects on growth parameters under saline environment. The rice seeds had been primed with different seed priming approaches viz., hydropriming, osmopriming , redox priming , chemical priming, hormonal priming and they were germinated under salinity stress of various concentration of NaCl. Growth attributes were calculated and Salt stress was evaluated based on visual symptoms according to the Standard Evaluation System (SES) score. All the priming techniques show promising results.
