Abstract
In order to investigate the effects of treatment of Salicylic Acid on photosynthetic system of two varieties of grapes (Vitisvinifera L. and Seedless White), under drought stress conditions, a factorial experiment was performed in terms of the scheme of totally random blocks. Watering cycles included intervals of 5, 10 and 15 days, and Salicylic Acid included concentrations of zero, 1 and 2 m . The results showed that by increasing drought stress, number parameters and leaf area, relative content of leaf water, transpiration, stomatal conductance, and pure photosynthesis had significant decrease in comparison to control treatment. And leaf thickness and stomata numbers increased significantly. Also the results revealed that the rate of leaf numbers, leaf thickness, stomata numbers, relative content of leaf water, pure photosynthesis and transpiration of Vitisvinifera L. was more than Seedless White. And the area of leaf and stomatal conductance in Seedless White grape was more than Vitisvinifera L. grape. Foliar application of Salicylic Acid resulted in increasing the number and the area of the leaf, leaf thickness, transpiration, stomatal conductance and pure photosynthesis. Generally, the results showed that Salicylic Acid can decrease drought deterrence stress effects on grape growth and VitisviniferaL. grape in comparison to Seedless white grape is more resistant to dryness.
