Physiological responses of seven varieties of soybean [Glycine max (L.) Merr.] to salt stress

In agriculture, salinity is one of the most significant abiotic stresses that plants confront and harms agricultural productivity, physiological, growth development processes. present study, there were 7 different varieties soybean (Ajmeri, William-82, D.A, PSC-60, Rawal-1, NARC-1 NARC-2,) tested under NaCl concentration level (0 mM 150 mM) to determine their physiological performance control experimental conditions. The investigation aimed select salt tolerant varieties. Under stress, have differed significantly in biological yield, chlorophyll contents, antioxidant activity ionic concentrations. results showed among seven evaluated NARC-2 are producing higher yield than others NaCl. produced biomass comparison with other similarly enhance by decreasing catalase activity. relative water content (RWC) was measured 15, 30, 45 60 days after treatment applied, as well at harvest time, along grain characters related yield. differences yield-associated when exposed salinity. had a greater impact on Ajmeri William NARC-2. NaRC-1 70% 65% respectively, while yields 41% 38% respectively. salinity-induced decrease traced fewer pods per plant, seeds pod lighter weight 100 grains. However, number plant affected compared characters. It also observed Na+ ion concentrations elevated shoot stress all low SDS-PAGE revealed variations protein profile seedling shown unique banding pattern molecular 130 kDa. indicate (NaCl) triggered an response (NARC-1 NARC-2) Glycine max (L.).
