Ecological and biological characteristics of Polygonatum multiflorum (L.) All. in Mordovia

The paper discusses some of the ecological and biological characteristics of a perennial herbaceous plant – Polygonatum multiflorum seeds. Liliaceae. It is of interest due to the fact that the number of this species of the forest-steppe zone is reduced due to the increasing anthropogenic load. In addition, P. multiflorum is a valuable medicinal and ornamental plant. The studies were conducted in 2016–2017 on the territory of the Republic of Mordovia, in the surroundings of large and provincial cities. The study revealed the spatial and age structure of the four coenopopulations plants. The general terms of the vegetation P. multiflorum and the duration of the individual stages of plant development were determined. The level of potential and actual fruit formation is established. P. multiflorum plants were found scattered or in groups, but most often, the density was 3–4 individuals/m². The studied coenopopulations P. multiflorum are mostly normal, full-term. Renewal can be carried out both due to seeds and vegetatively. The latter is observed under favorable conditions for the P. multiflorum of existence. The studies have confirmed the view that the P. multiflorum is a fairly vulnerable forest species and there is a real risk of loss of the natural gene pool of this wild plant.
