Abstract
Information is given on the study of the species composition of native and alien synanthropic plants distributed in the flower beds of Yakutsk. Geobotanical studies were conducted by route method during 2018-2019 and 2021-2022. Fifty-nine species of weedy plants belonging to 20 families and 49 genera were noted in the city's flower beds. The leading families in terms of number of genera and species are Asteraceae, Brassicaceae. Terophytes (51.7%) with high reproduction rate and laboratory germination of their seeds ranging from 70 to 100% occupy a significant share in the plant species composition. The spectrum of geographic groups is dominated by species with a wide range, often highly competitive, which allows them to successfully inhabit new habitats. The dominance of mesophytes and xeromesophytes was revealed in relation to the degree of soil moisture among synanthropic species in flower beds. The species composition of synanthropic plants consists of native (50.8%) and adventive (49.2%) components. The basis of the aboriginal fraction consists of polycarpics (66.6%), the adventive species are represented mainly by annuals and biennials (82.7%), which easily adapt to the conditions of Central Yakutia, surviving the winter in the form of seeds. Laboratory germination of seeds of the majority of studied annual species is high and ranges from 70 to 100%. Average and low seed germination is characteristic of the seeds of perennial species. Assessment of occurrence and abundance of plants made it possible to identify the main littering species of flower beds. Species with high occurrence and abundance were adventive Chenopodium album L. (occurrence 68%, abundance score 1-4), Chenopodium glaucum L. (occurrence 62%, abundance score 0-4), Stellaria media (L.) Vill. (occurrence 62%, abundance score 0-4), etc.
