Abstract
Background. Artemisia sieversiana Willd. is a Eurasian species of the genus Artemisia L., belonging to the group of monocarpic annual/biennial plants. This species is not only a weed, but also one of the valuable medicinal plants of folk and Tibetan medicine. However, the data about the species' biology and ecology are very scanty. The study of cenoflora with the occurrence of A. sieversiana is one of the main tasks for the understanding of the species.
Results. In the Transbaikalian vegetation, A. sieversiana is represented by three morphotypes: (1) the forest-steppe morphotype, when individual plants are short (up to 20-25 cm) and characterized by a very compressed paniculate inflorescence, large baskets sitting one by one on very short stalks or peduncles; (2) the adventive one, characterized by large sizes, the stem in the upper half ramified into a large paniculate inflorescence, and the plant height reaching up to 100 cm; and (3) the fallow one, with plants of average height (20-40 cm), when the panicle is well developed, but systems of secondary flower-bearing shoots in the sinuses of the upper leaves are relatively poorly formed. In the flora of communities where A. sieversiana is present, 146 species of higher vascular plants belonging to 42 families and 74 genera were identified. Asteraceae (24%), Poaceae (11%), Fabaceae (7%), Rosaceae (7%), Brassicaceae (6%) occupy the leading position in the spectrum of multispecies families. Among the life forms, perennial herbaceous plants (48%) prevail as well as annual/biennial herbaceous monocarpicles (28%). Species belonging to the taproot (34.2%), long rhizome (15.06%), racemose root (9.5%) and root sucker (7.5%) groups are widely represented as a result of adaptation to abrupt temperature fluctuations and lack of moisture. Ecological analysis showed that xerophytes (25%), mesoxerophytes (22%) and xeromesophytes (21%) occupy the prevailing positions, which attests to the extreme continental climate in the region. Species of the mesophyte group (15%) are represented by medium-scale percentage; these are mostly the plants of more moderately moist soils. According to the ratio of geographic elements, meadow-steppe and steppe Eurasian (23%), polyzonal (weedy), and Holarctic (20%) species dominate in the cenoflora of A. sieversiana communities, with Central Asian desert-steppe species (14%) also present.
Conclusion. The analysis shows the special features of the vegetation of plant communities with A. sieversiana. Species of the meadow-steppe geographic group with a wide range of distribution are typical for them. Predominance of taproot mono- and polycarpicles of xerophytic ecology was observed. In Transbaikalia, A. sieversiana is differentiated into three morphotypes. With this, the forest-steppe type, if compared with the adventive and fallow forms, is distinguished by a set of morphological traits in its vegetative and generative spheres, which may lead to its recognition as a separate botanical variety.
