Effect of drought stress was investigated at water potentials of-0.2 &-0.4 MPA (by using PEG 6000) on okra germination and seedling growth. In this study, percent germination, average time necessary for germination in day, radical and plumule length, fresh and dry weight of okra seedlings were measured. Effect of ascorbate and salicylic acid and interaction of these tow substances were investigated on germination and seedling growth under normal condition and dry conditions. Drought inhabits from germination and seedling growth in this plant. Ascorbate and salicylic acid increase germination and decrease of average time necessary for germination under drought conditions. The seeds that were treated by ascorbate and salicylic acid, radical and plumule length, fresh and dry weight of radical and plumule were increased. Results showed that ascorbate and salicylic acid decrease effects and damages of drought stresses on okra germination and seedlings growth. In general, adding salicylic acid and ascorbic acid significantly relieved the harsh effects of drought on okra germination and growth parameters and it seems that ascorbate and salicylic acid were able to enhance the tolerant ability of the plant to drought stress.
