Ontogenetic strategies and tactics based on morphometric indicators of the structure of leaves of the meyer lemon Variety

Currently, serious global environmental degradation, as well as an increased level of human impact on the environment, including flora biocenoses, directly affect the conservation and protection of biodiversity. In this context, it is important to evaluate the survival strategies of plant species dispersed in the Earth‘s biosphere when determining the degree of adaptation of species to the conditions of their growth environment. The paper claims that the Meyer lemon variety allows one to identify the mechanisms of species adaptation, the type of ontogenetic strategy based on the analysis of morphological indicators in the context of changing growth conditions and, on this basis, species of economic importance depending on the conditions of their cultivation. In the Meyer Lemon variety, survival tactics are defined as a divergent convergent type, in which morphometric indicators of leaf plasticity increase and then weaken under protective conditions.
