Spatial and Age Structure and Seed Production ofDelphinium macropogonProkh. in the Population from Talgi Gorge

The spatial structure, demographic indicators, and seed productivity ofDelphinium macropogonProkh. in Talgi gorge are considered. It was noted that the population ofD. macropogonis characterized by significant sparseness and low seed productivity. The age structure of the population is incomplete with the predominance of young generative individuals. It was shown that the demographic variables analyzed using the recovery index (Ic= 0.24) and the index of vitality (IVC= 0.88) are depressive. According to the Delta-omega criterion, the population refers to the ripening type. A comprehensive analysis of the population characteristics ofD. macropogonin Talgi gorge showed that the processes of population of the territory occur at a low level of density, which is hampered by weak growth due to the young fraction and low seed productivity and germination.
