Seed priming improved salt-stressed sorghum growth by enhancing antioxidative defense

Seed priming is regarded as a beneficial and effective method enhancing performance of plants grown under stress conditions. This study illustrated the effect of four seed priming agents (2% H(2)O(2), 52 mM NaCl, 50 mM KCl, 250 mM MgSO(4)) on two sorghum cultivars (Canada sorghum CFSH-30 and sorghum...

Sumario:Seed priming is regarded as a beneficial and effective method enhancing performance of plants grown under stress conditions. This study illustrated the effect of four seed priming agents (2% H(2)O(2), 52 mM NaCl, 50 mM KCl, 250 mM MgSO(4)) on two sorghum cultivars (Canada sorghum CFSH-30 and sorghum ‘1230’) grown in saline soils. Sorghum growth characteristics and biochemical parameters were investigated. Seed priming treatments alleviated the adverse effects of salt stress by decreasing MDA content and enhancing antioxidant enzymes (CAT, POD and SOD) activities and proline content, and hence increased sorghum fresh and dry weight. In terms of various parameters, sorghum ‘1230’ was more suitable to be grown in saline soil, and 52 mM NaCl and 50 mM KCl were the optimum priming agents to improve the performance of salt-stressed sorghum.
