The invasion of aggressive adventive plants in the territory of the Abkhazia Republic has a significant impact on the loss of biodiversity and the imbalance of ecosystems. In this regard, monitoring of the invasive component of flora is an urgent task. The aim of work was to study the biological features of invasive species Conyza canadensis under the conditions of Abkhazia. The research objectives included the study of morphometric parameters of the species and their variability.
The article presents the results of studying the morphological state of three populations of Delphinium pubiflorum on the basis of quantitative traits measured over four years during the period of mass flowering of plants. The greatest difference in quantitative characteristics was shown by the populations from the Krasnoarmeisky and Tatishchevsky districts of the Saratov region.
