Abstract:

Chickpea seeds of two varieties magnetoprimed with 100 mT 1h static magnetic field were subjected to salinity stress (80 mM NaCl) from germination to maturity. Physiological traits such as total root length, surface area, volume of the roots, plant height, leaf area and dry weight were significantly improved in plants from magnetoprimed seeds of both the varieties. Total chlorophyll content enhanced significantly under priming in leaves of Pusa 1053 compared to Pusa 256 under all treatments. Under salinity, the Na+/K+ ratio was less in plants from primed seeds compared to unprimed seeds irrespective of the plant parts indicating the regulation and partitioning of Na+ at cellular level which helps in imparting tolerance to chickpea genotypes under stress. We hypothesise that Ca2+ mediated signaling that results due to magnetic field exposure (ion cyclotron theory) and salinity stress may signal the activation of SOS pathway that regulates ion homeostasis in plants. Our results also evinced that magnetopriming of dry seeds can be effectively used as a pre-sowing treatment for mitigating adverse effects of salinity in chickpea genotypes.
