Abstract

To evaluate the potential of seed priming tools in soybean salt stress tolerance with improved plant growth and biomass content. Soybean seeds were primed with 5 different priming agents (proline, sodium nitroprusside (SNP), glycienbetaine, hydrogen peroxide & mannitol) then germination under laboratory conditions using 100mM NaCl stress condition was evaluated. Results indicated that SNP (nitric oxide donor) was found most effective agent for growth promotion, while unprimed treatment decreased germination, growth and biomass related parameters. SNP-primed seeds had a higher germination percentage (82%) and seedlings were exhibited increased proline content (105%) as compared to unprimed treatment. The protective mechanism of SNP against oxidative stress was correlated with lower lipid peroxidation (MDA content). Notably, the ability to maintain biomass level (41% reduction) as well as chlorophyll content indicated a role of SNP in alleviation of salt stress and induce tolerance. Altogether, our results highlight that exogenously SNP could be employed to attain better growth and development of soybean and perhaps other legumes under salt stress.
