| چکیده | ||
| This research was conducted in order to investigate the effect of foliar application of different concentrations of salicylic acid and jasmonic acid on the morphological, physiological and biochemical characteristics of garden thyme subjected to water deficit stress conditions. Research was conducted as split factorial randomized complete block design with three factors and three replications at the Varamin and Absard research field in the farming year of 2019. Irrigation was applied as normal irrigation and water deficit stress. The sub factors included foliar application of salicylic acid and jasmonic acid at different concentrations, performed as factorial Random Complete Block design with three replications. Foliar application of salicylic acid and foliar spraying of jasmonic acid were performed at three concentrations: control (zero), 25 and 50 mg L-1 and: control (zero), 1 and 2 mg L-1, respectively. Results demonstrated that water deficit stress caused a significant decrease in plant height, fresh and dry weight yields, chlorophyll a, b and total chlorophyll content, and increased the amount of proline. Also, the interaction of foliar application of different concentrations of salicylic acid and jasmonic acid reduced the destructive effects of water deficit stress and increased the tolerance of the medicinal plant garden thyme. In fact, it can be said that these substances indirectly reduced the activity of these enzymes and improved plant growth conditions. | ||
