Abstract

In accordance with the morphological nature of plant species, the ontogenetic tactics of convergent, divergent, convergent-divergent and indefinite types differ based on the nature of the variability of adaptation to environmental conditions. And also in many studies, plants are grouped according to the ontogenetic strategy of stress and protective stress. The ontogenetic stress strategy states that the morphological characteristics of the plant, including the morphometric parameters of the leaf structure, decrease with the deterioration of the growth environment. In this regard, it is noted that this feature is most often observed in succession of species. The ontogenetic strategy of the protective-stress state establishes a state of stability on the basis of mechanisms aimed at maintaining the integrity of the morphometric parameters of plant leaves under the influence of growth factors.
