Endo-adaptive mechanisms of mesophytic plants’ functioning as a component of ecosystem resistance

Abstract

The ecological state deterioration of the biosphere contributes to the formation of structural-functional mechanisms of plants’ adaptation to the synergistic influence of negative factors at different levels of living systems’ organization. A complex algorithm of the plant organism reaction response to any adverse factor includes a wide range of histological-metabolic adaptive mechanisms that provide a nonspecific reaction and are responsible for increasing the plant organism resistance. Aim is the investigation of endo-adaptive specificity of mesophytic plants’ formation as an ecosystem resistance component. Methods are experimental research, quantitative and anatomical analysis, mathematical and statistical processing of the obtained data. The article presents the histological-functional specificity of Portulaca oleraceae L. vegetative organs under chloride load and without it in the Ukrainian south conditions. It is proved that the various parameters study of plants’ metabolism and anatomical-morphological reconstruction plays an important role in studying the salt resistance mechanisms, which determine the existence of mesophytic plants under stressful environmental changes. It is shown that adaptability is an equal component of two interdependent processes (the development of damage caused by stressors and the restoring the values of structural-functional parameters), which generally forms an endo-adaptive mechanism of plant functioning and ensures steadiness of ecosystem stability.
