Estimation of the temporal and dimensional structure of Caragana arborescens Lam. in the forest parks of the City of Yekaterinburg

Abstract

The article is devoted to the evaluation of the temporal and dimensional structure of Caragana arborescens Lam. in various coenotic conditions in the Uktussky and Shartashsky forest parks of Yekaterinburg on the basis of individual parameters (ontogenetic state and morphometric indicators). For the first time, a quantitative characteristic of the manifestation of organismal indicators in each ontogenetic state of Caragana arborescens in these forest parks was obtained. Peculiarities of Caragana ontogeny in 7 habitats were revealed. Karagana in two forest parks have similar parameters both in ontogenetic structure and morphological sizes of tree crowns. Individuals in the Shartashsky Forest Park are slightly larger than those in the Uktussky Forest Park, which is confirmed by the results of two-way ANOVA. There is a high level of correlation between tree crown sizes in different directions. Changes in the size parameters of tree crowns for various ontogenetic states are also characterized. The obtained ontogenetic and quantitative patterns of growth of C. arborescens are of scientific interest, since they make it possible to make a prediction regarding the further development of the species, and also contribute to understanding the fitness and development of this species in environmental conditions specific to the region. © 2023 Author(s).
