Effect of salicylic acid on photochemistry and antioxidant capacity in Salvia nemorosa plants subjected to water stress.
Oxidative stress is commonly induced when plants are grown under drought stress conditions.To analyze how salicylic acid (SA) can partly alleviate drought-induced oxidative stress and negative impacts of drought on physiology and growth of Salvia nemorosa plants, we investigated the physiological responses of S. nemorosa to SA application under drought stress. The treatments were composed of Co...
متن کاملAn Assessment of Oxidative Stress and Antioxidant System Activity in Alfalfa Plants Treated with Different Forms of Mineral Arsenic
Arsenic (As), a metalloid and unnecessary element, is highly toxic to living organisms. It can be accumulated in the environment and enter the food chains through uptake by plants. The present study was designed to assess the response of antioxidant defense system of alfalfa to As (As0, As3+ and As5+) induced oxidative stress at four rates (0, 100, 200, and 300 µM) as a completely randomized de...

متن کاملInteraction of polyamine and proline on the activity of enzymatic and non-enzymatic compounds in the peel of three Citrus species under low temperature stress
Plants activate antioxidant defense mechanisms under stress, which help maintaining the structural integrity of cell components and possibly reduces oxidative damage. Low temperature stress leads to the production of reactive oxygen species and oxidative damage to plants. In this study, the effect of putrescine and proline on reducing the production of reactive oxygen species and increasing th...
متن کاملEffect 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...
