The study of physiological and biochemical aspects of the application of abscisic acid in plants for improvement of the quantitative and qualitative product under water deficit stress condition

Abiotic stress includes a number of stresses that is created by the environment condition. Drought stress is one of the most important environmental stressors that affect the production and survival of plants. Among the important strategies in preventing drought and preventing waste of water resources in the agricultural sector, it is possible to increase the irrigation efficiency, selection of drought tolerant species, use of moisture absorbing materials and use of plant growth regulators such as abscisic acid. Abscisic acid can have two basic approaches. Firstly, as a key hormone, it increases the antioxidants and improves the activity of antioxidant enzymes and physiological traits, which increases plant resistance to environmental stresses such as drought stress, and secondly, in the development of seeds and fruits, and increasing the quantity and quality of the product is also effective. This plant growth regulator, in addition to the positive effects it could have, has not environmental threat. On the other hand, when the possibility of commercial abscisic acid production is provided, it can be used at low dosages and low frequency applications, thus reducing the cost of using abscisic acid and allowing it to be used extensively.
