fluctuation of physiological characteristics and tolerance signals in parent's seeds and Seeds exposed to drought stress in cotton (Gossypium hirsutumL.) plant.

摘要: Drought stress is a limiting factor in growth and production in more than 30% of the world's cultivated areas. One of the ways to deal with drought stress is to cultivate plants that are more resistant to this stress and cotton is one of these plants. There is little information about the physiological and biochemical properties of cotton under stress conditions and therefore this study was designed to identify the fluctuation of physiological characteristics and tolerance signals in mother seeds and seeds under drought stress in cotton plants. Experimental factorial, in the form of a randomized complete block design, in 5 seed treatments (including 4 levels of stressed seeds and non-stressed seeds) and stressed seeds at 4 levels of irrigation (rainfed, 33%, 66%) And 100% of the field capacity of the farm) was implemented. In this study, the seeds used were exposed to drought stress in 3 stages during different cropping seasons …
