Abstract :
During the life cycle, plants are exposed to various abiotic and biotic stress factors that adversely affect their growth, development and productivity. Drought is one of the stress factors affecting the decline in plant growth and productivity worldwide. In this study, the effect of water deficiency caused by different concentrations of mannitol (5%, 10%, and 20%) on the germination of seeds of two varieties of peas (Petit Provencal and Joff) was studied. The results of the study showed that the germination percentage and germination potential of both pea varieties decreased with increasing mannitol concentration compared to the control. The Petit Provencal variety had a higher percentage of germination, germination potential and vigor index of drought resistance and this variety was considered more tolerant to drought stress.
