Study of reproduction capacity and ex situ conservation of campanula Armazica Charadze (Campanulaceae)
2017
Reproduction biology of species of primary conservation concern-Campanula armazica Charadze, included in the Red Data List of the Caucasus Plants, was studied in order to establish the reasons of the decline of wild population and conservation strategy development. Current state of its wild population was evaluated and issues, such as: phenological phases of development (vegetation, flowering, fruit seed and maturation), processes of development of female and male generative spheres, peculiarities of pollination, fertilization, potential for seed formation and germination connected with elaboration of the proper conservation strategy were researched. The results of our studies proved normal course of seed formation processes. The species is well adapted to the conditions of its natural habitat. Thus, disappearance of the species from the previous distribution areas is not due to biotic factors. Conservation ex situ, in particular, preservation of seed stock in the Caucasus Regional Seed Bank of the National Botanical Garden of Georgia and duplication of seed collections in the Millennium Seed Bank of the Royal Botanical Garden, Kew, and in situ artificial sowing of seeds in places of the former distribution of C. armazica and long-term monitoring of the site are offered as the means for the protection of the studied species.
