Abstract
The article presents the results of studying the population characteristics of Convallaria majalis L. from Convallariaceae family in the conditions of the coniferous-broadleaf forests of the Kirov region. The studied species is considered as rare in many regions of Russia. The research was carried out during the 2023 growing season in the Kirov region (Malmyzhsky and Vyatsko-Polyansky districts). The region is located in the north-east of the European part of Russia, the study areas belong to the subzone of coniferous and broadleaf forests. Four cenopopulations (CP) of Convallaria majalis L. in various types of plant communities were studied. As a result, it was found that the left-sided type of the ontogenetic spectrum is predominant in the studied cenopopulations. According to the delta-omega classification, the studied cenopopulations are young, as indicated by the values of the age index (Δ = 0.122–0.193) and the energy efficiency index (ω = 0.412–0.528), which are within the values typical for the population.
