Population structure and peculiarities of morphology Geranium tuberosum - species of Red Book of the Republic of Crimea
The phytocoenological characteristics of the Kerch Peninsula phytocoenoses in which Geranium tuberosum L. grows are given. Morphology peculiarities of the species vegetation organs (stolons, tubers and leaves) identified. The characteristic of the G. tuberosum coenopopulations about spatial structure, methods of self-sustaining numbers in various phytocoenotic conditions is analyzed. G. tuberosum on the Kerch Peninsula is phytocoenotically confined to demutatio- digressions communities (ass. Geranietum artemisieto-festucosum) and phytocoenoses of meadow steppes (ass. Geranietum dactyleto-festucosum), reaching dominant role in both. It is well adapted to urbanized ecotopes. G. tuberosum has two types of changes in underground shoots: underground stolons and tubers; in the aerial part, it does not form a rosette, the main leaves develop from the tubers gemma. In the demutatio-digressions community (N 1), the population is predominantly clonal, with a limited seed propagation. The spatial sructure of individuals in the meadow steppe community is random, in the demutatio-digressions community is gregis.
