abstract

one of the effects of reducing water content on soil is reduction of growth and development of seedlings and variation of field development of them. it was found that seed priming improves some characteristics of seedling and plant. an experiment was conducted for evaluating the effect of seed priming by salicylic acid on some characteristics of barley seed at early growth stages, antioxidant enzyes activity and proline content under drought stress. the first factor was priming with salicylic acid (zero, 50, 100 and 150 ppm) and the second factor was three levels of drought (zero, -6 and -12 bar). the results showed that sa pretreatment effect on germination percentage, germination rate, dry weight, protein, catalase, ascorbat peroxidase activity and proline content were significant. the interaction effect of stress  seed treatment on leaf number was not significant but the main factors were significant. the highest germination percentage (98.7), germination rate and seedling dry weight were found at 100 ppm concentrations of salicylic acid. under drought stress conditions, protein content decreased but salicylic acid pretreatment increased the valuet. also, drought stress conditions increased enzyme activity and proline content, but salicylic acid pretreatment decreased them.

Effect of Salicylic Acid Application on Oxidative Damage and Antioxidant Activity of Grape (Vitis vinifera L.) Under Drought Stress Condition

Adaptation and defense responses are the consequences of exposure to drought stress in plants. Salicylic acid (SA) as a natural signaling molecule poses a significant impacts on various aspects of plant growth and development. This study investigates the effects of SA on carotenoids content, lipid peroxidation rate and antioxidant enzymes activities. A pot experiment was conducted using a facto...

Effect of Drought Stress and its Interaction with Salicylic Acid on Fennel (Foeniculum vulgare Mill.) Germination and Early Seedling Growth

Environmental stress, particularly drought stress can play an important role in reducing plant growth especially during the germination stage in arid and semi-arid regions in Iran. For cultivation of medicinal plants in arid and semi-arid areas, the assessment of their tolerance is very important. In this research, in order to evaluate the effects of salicylic acid pretreatment on enhancement o...
