Features of the adaptation of alien species LAMIUM PURPUREUM L. of secondary area
Introduction. The negative impact of non-abiotic plant species on the environment is increasing every year in Ukraine. At present, this problem has become extremely important, since invasions of adventitious plant species violate the structural and functional relations of forest ecosystems.
L. purpureum is a typical representative of grassy plants, which reflects such changes.Purpose. The aim of the present study was to analyze of populations of L. purpureum in the secondary area on the example of the territory of the Right Bank of Forest-Steppe zone.
Methods. Study sites were all located within the Right Bank Forest-steppe on the territory of the Kyiv and Vinnytsia regions.An ecological profile consisting of six experimental plots, depending on the recreational gradient in the urban forest, was established in accordance with the principles of comparative ecology. Plant complex was established according to the geobotanical and ecological methods. Assessment of the morphometric parameters of the population L. purpureum was established in accordance with generally accepted methods.
Results. Weak, medium and strong degrees of environmental transformations accompanied by ecological and coenotic adaptation changes of species populations was established. The analysis of morphometric parameters (plant height, number of flowers, number of leaves, number of shoots, diameter of the shoots, average area of a separate leaf, total leaf surface) was shown.Analysis of the variability of characteristics through the coefficient of variation showed that the investigated morphometric parameters were varied within the range of 21,0% -89,2%.The coefficient of variation increases with the potentiation of anthropogenic pressure transformation was established. Analysis of the vital composition was showed the domination of a prosperous type of population. The quality index was within the range of 0,315-0,435.
Conclusion. The various ecological conditions and coenotic confinedness have caused a significant range of values of morphometric parameters of the populations of L. purpureum.The number of flowers and the number of leaves per individual were the most significant parameters. The height and diameter of the shoots were more stable.
