Opis:
This review presents the results of multi-year efforts for the development and integral investigation of the collection of Deschampsia antarctica É. Desv. plants originated from the maritime Antarctic. To create the collection, we have optimized the procedures and conditions for germination of seeds and generation of aseptic plants in vitro together with their subsequent clonal propagation, long-term in vitro culture, and acclimatization of plants to pot culture, and finally produced fertile plants able to set viable seeds. The collection of plants cultivated in vitro and in pots is consisted of clones of 22 different genotypes originated from eight island populations from the Argentine Islands – Kyiv Peninsula region. Some of these clones have been successfully cultured for more than ten years and were found to be genetically stable over this period. The collection was shown to be heterogeneous in a number of variables. The morphological and anatomical characteristics of the plants, as well as the data of karyological, molecular cytogenetic, molecular genetics, and biochemical analysis are presented. The created collection of D. antarctica plants can provide a valuable plant material with well-studied characteristics grown under controlled conditions to perform experimental research on the mechanisms for plant adaptation and resistance to various abiotic factors of Antarctic environment. Furthermore, development of the collection and its comprehensive characterization form the basis for further biotechnological developments focused on the use of this Antarctic plant as a source of biologically active substances, which can potentially be used for therapeutic and prophylactic purposes.

Opis:
The forest conditions in the Central Aimag of Mongolia, located in the southern part of the Baikal catchment area, near the southern border of the forest-steppe subzone, were examined within the framework of this study. The field materials collected in the summer 201–2018 at the Zuunmod Model polygon serve as the core of the study. An ecosystem map of the Model polygon with the scale 1:50 000 and the Key plot with the scale 1:5 000 was drawn up using World Viеw-2 satellite imagery data (2016). The proven method of botanical indication of forest growth conditions is as follows: identification of the ecologic and coenotic groups of plant species, calculation of the moisture coefficient based on the ratio of the number of species included in the groups characterizing the extreme conditions of the moisture gradient and distribution of communities in accordance with the values of the gradient in the ecological series. Communities of stages of ecological series serve as indirect indicators of the forest conditions: Stage I: Кu <1, insufficient humifying for tree growth, Stage II: Кu 1–2, average humifying, Stage III: Кu >2, sufficient humifying for tree growth. The stages also correspond to the landscape conditions and the character of the vegetation cover.
