Assessment of the quality and germination capacity of seed in the plant species of conservation сoncern deposited in the National Seed Bank of Georgia.
2022
The paper deals with the results of assessment of seed collections of 47 species of Georgia’s flora endemic to Georgia and Caucasus deposited at the National Seed Bank of Georgia (National Botanical Garden of Georgia). The studied species belong to the 14 botanical families and 24 genera. Restoring populations of endangered and especially rare endemic species in the wild has long been on the agenda of plant conservationists and for this aim it is very important to ensure safe storage of seeds obtained from plants growing in the natural environment. As a result of our experiments the germination capacity, seed quality and terms, necessary for the germination of seeds have been established for the particular plants species. Germination tests were carried out in the laboratory in conditions of controlled environment (temperature, illumination). Analysis of the experimental results revealed various factors that determine the duration of the dormancy period of seeds and their ability to germinate. The paper is richly illustrated with high-resolution photographs. Tab. 1, Fig. 1, Ref. 12.
