The Poaceae family species in the collection of the Botanical Garden of the Institute of Biology, Komi Science Centre, Ural Branch, RAS

The paper presents the results of a long-term study (2010–2019) of the ecological and bio¬logical characteristics of the collection of species of the Poaceae family, which at the end of 2019 included 32 species (45 samples) belonging to 16 genera. The genus Festuca L. is represented by the largest number of species – 10, the genus Bromopsis Four. contains 4 species, three genera – Elymus L., Phleum L. and Poa L. – two spe¬cies each. The remaining 12 genera are repre¬sented in the collection by only one species. Arrhenatherum L., Alopecurus L., Beckmannia Host., Briza L., Calamagrostis Adams., Dactylis L., Deschampsia Beaw, Hordeum L., Leymus L., Melica L., Miscanthus Anderss, Phaloroides Wolf. All species of the collection fund are di¬vided into three groups according to the rate of their development: 16 species are classified as early plants, their vegetation period is 60–75 days; medium-sized plant group (76 – 92 days) includes 9 species; late plant group (more than 95 days) – 7 species. Long-term research on a complex of economically significant features made it possible to identify promising cereal plants (12 species) that can be used as ornamen¬tal plants for landscaping in the northern re¬gion. It is shown that among the selected prom¬ising species there are representatives of all three groups of cereal plants, distinguished by the rate of development. Thus, the group of plants of early development includes 5 promis ing species: Festuca rubra, F. pratensis, Briza media, Deshampsia cespitosa, Melica nutans. Cereals belonging to the second group are Festuca ovina, F. pseudodalmatica, Elymus sibi-ricus, Dactylis glomerata, Bromopsis tyttholepis. The group of late-growth cereals includes Beck-mannia eruciformis and Phleum pratensis. Brief data are given for each promising species: morphological description, ecological relevance, geographical distribution, timing of phenological phases, reproductive ability, possibilities of decorative use.
