Seed Priming Treatments to Improve Heat Stress Tolerance of Garden Pea (Pisum sativum L.)

Heat stress seriously affects the production of cool-season food legume crops such as garden peas. Seed priming is a widely used technique that increases germination and improves plant growth development, resulting in better field performance higher yield crops. In current study, we investigated three seed treatments—hydropriming (dH2O), osmopriming (2.2% w/v CaCl2), hormopriming (50 mg L?1 salicylic acid—SA)—and their effect on germination, initial seedling physiological traits two novel pea cultivars, under optimal conditions heat stress. with H2O, CaCl2, SA enhanced both via significant improvements energy, final mean time, rate, vigor index, shoot length, root fresh weight, dry elongation relative water content, chlorophyll membrane stability compared to control. The highest examined parameters was achieved by suggesting these treatments could be improve tolerance pea, after extensive trials.
