Abstract

Soybean (Glycine max) is a potential legume crop, but it cannot thrive in mild salinity. Salicylic acid (SA) is a renowned plant growth hormone that improves tolerance to saline conditions. Hence, the study was performed to understand the functions of priming seeds and supplementation of SA in modulating salt tolerance in soybean seedlings. When exposed to salt stress, soybean seedlings showed considerably higher contents of hydrogen peroxide (H2O2) and malondialdehyde (MDA) while having decreased germination and growth factors, water contents, and photosynthetic pigments. The germination rate, final germination percentage, germination index, germination energy, and seed vigor index considerably improved while the mean germination time decreased in the SA-primed seeds. The results also revealed that SA supplementation increased seedling traits, leaf water content, chlorophyll, and carotenoids and lessened H2O2 and MDA content under salt stress. Germination of seeds, seedlings growth traits, plant pigments, H2O2, and MDA content with the NaCl and SA treatments were found to substantially interact with each other according to both hierarchical clustering and principal component analysis. Based on the results, SA might be used as a seed priming and exogenous chemical to assist soybeans grow faster under salinity stress.
