The unsolved problems of plant physiology of stresses, having systemic features are interpreted in this paper. It was make a critical review of the Selye´s definition of stress based
on effect of stressors on the plant organisms. It was showed that dynamics of plant reaction under action of the drought as a transition processes and can be divided in three discrete fazes: I-depression of physiological processes; II-adaptive reactivation and III- destruction. Stress response of plants depended on many factors and theirs resistance is reflected by the rate of physiological processes at first two phases and to threshold level of soil humidity. The adaptive and destructive character of plant stress reaction is analyzed. |
