Alleviation of Salt-Inhibited Germination and Seedling Growth of Kidney Bean by Seed Priming and Exogenous Application of Salicylic Acid (SA) and Hydrogen Peroxide (H2O2)

Salinity is a dominant obstacle to the proper germination of seeds, growth seedlings, and, consequently, production crops. The priming seeds with different treating agents can efficiently impart salinity tolerance. Kidney bean nutritious and popular vegetable crop in world. Literature shows that salt stress negatively disturbs kidney beans. In present research, we investigated potentiality salicylic acid (SA) hydrogen peroxide (H2O2) as exogenous alleviate salinity-inhibited were pretreated SA (1 mM 2 mM) H2O2 (0.1 0.15 soaked normal tap water (hydro-priming) for 60 min. addition, control experiment, untreated used. Finally, primed subjected (150 NaCl). Our results exhibited considerably lowered percentage (GP), index (GI), seed vigor (SVI), shoot length (SL), root (RL), shoot–root fresh dry biomass, plant growth. also significantly decreased relative content (RWC) photosynthetic pigments such chlorophyll, carotenoids, lycopene, beta-carotene contents. SA- H2O2- hydro-priming stimulated GP, GI, SL, RL, SVI, seedling Data revealed supplementation enhanced RWC pigments. When compared other treatments, pretreatment 1 was determined be comparatively more effective at imparting tolerance Overall, these results, via heatmap principal component analysis, uncovered applications improve enhance characteristics
