Abstract
The article provides information on the study of the dynamic processes occurring in cenopopulations of 16 species of medicinal plants used both in scientific and folk medicine (Achillea asiatica Serg., Artemisia frigida Willd., Chamaenerion angustifolium (L.) Holub, Comarum palustre L., Geranium pratense L., Dasiphora fruticosa (L.) Rydb., Fragaria orientalis Losinsk., Mentha arvensis L., Pulmonaria mollis Wulfen ex Hornem., Potentilla anserina L., Potentilla bifurca L., Ribes spicatum E. Robson, Rosa majalis Herrm., Rubus matsumuranus Levl. Et Vaniot, Spiraea salicifolia L., Vaccinium uliginosum L.): age coefficient, recovery index, development rate. Identification of the population confinement of species to existing ecological and coenotic conditions, determination of demographic parameters, study of the development dynamics, methods of self-maintenance and survival strategies serve as the basis for the rational use of plant resources. The stable and dynamically developing medicinal plant cenopopulations, with a high recovery index, with a tendency to develop towards rejuvenation, include the cenopopulations of Geranium pratense of the Ziminsky region, Pulmonaria mollis of the Alar and Irkutsk regions, Rubus matsumuranus of the Irkutsk region. The results of the analysis of the cenopopulation dynamics of the studied species made it possible to identify stable, dynamically developing cenopopulations and recommend them for use.
Highlights
The study of plant resources of Baikal Siberia for the purpose of their rational use and protection remains one of the main tasks of modern biology and medicine
Cisbaikalia is a region of the south of Eastern Siberia, located in the center of the Asian continent
Gradual aging is observed in the coenopopulation of Rubus matsumuranus (U = 0.98) of the Alar region, Fragaria orientalis, Rosa majalis and Spiraea salicifolia (U = 0.005-0.65) (U = 0.59-1.69) of the Alar, Ziminsky, Irkutsk and Nizhneudinsky regions (U = 0.1-1.33); Artemisia frigida (U = 1.28) of the Olkhonsky region; Comarum palustre (U = 1.33), Mentha arvensis (U = 2.36), Potentilla bifurca (U = 0.52), Potentilla anserina (U = 0.17) of the Irkutsk region; Pulmonaria mollis (U = 0.50) of the Ziminsky region; Ribes spicatum (U = 0.25-1.05), Rosa acicularis (U = 0.30-1.29) of the Alar and Irkutsk regions; Vaccinium uliginosum (U = 0.50) of the Olkhonsky region
Summary
The study of plant resources of Baikal Siberia for the purpose of their rational use and protection remains one of the main tasks of modern biology and medicine. Identification of the population confinement of species to existing ecological and coenotic conditions, determination of demographic parameters, study of the development dynamics, methods of self-maintenance and survival strategies serve as the basis for the rational use of plant resources. Ontogenetic and cenopopulation, introduction studies, identification of thickets of industrial importance, recommendations on scientifically grounded volumes of raw materials procurement, ecological-biological, biochemical and pharmacognostic studies, study of the technology of drying and processing of plant materials while preserving the maximum amount of biologically active substances, study the impact of recreational activities on the components of biocomplexes and other aspects considered by the authors will help to solve the problem of biodiversity conservation [124]
