In agriculture, interference between environmental constraints and plant life processes is a determining factor of crop productivity. Conservation of adapted phytogenetic resources is a tool to preserve biodiversity and ensure food security. The present experiment was conducted during 2022 and 2023 at Yahia Fares University of Medea, Algeria to study the response strategy of two indigenous legumes, pea (Pisum sativum L.) and chickpea (Cicer arietinum L.) genotypes to drought stress explored at seeds emergence and seedlings establishment stages. The experiment was laid out in a factorial completely ramdomized design (F-CRD). The seeds of both species were primed with different H2O2 concentrations (0, 2, 5, 10 and 12 mM) and germinated under water stress (5%, 10%, 15% of PEG) along with unprimed control (0%) using distilled water. Drought stress had significantly reduced germination in pea seeds than chickpea seeds. Primed chickpea showed high germination rates (+ 85%) at (15% of PEG), speed germination (SG) and seedling vigour (SVI) (+38%) and (+ 40%), respectively at (10% of PEG) compared to pea seeds. Maximum growth parameters: radical length, hypocotyls length, epicotyls length and whole plant increased about 38%, 30%, 50% and 10% respectively for pea seedlings grown under all treatments. Fresh and dry weights were significantly improved in pea plants than chickpea. Statistical analysis indicated significant differences in the combined impacts of the studied species, the primer concentrations and the drought stress intensity at P<0.05, P<0.01 and P<0.001. Our findings are beneficial to understanding the response mechanisms to drought stress for breeding programme of grain legumes.
