Abstract
The article analyzes for the first time the stocks of phytomass in the cenopulations of Tripleurospermum inodorum (L.) Sch. Bip and Leucanthemum vulgare Lam. on the territory of three natural regions of the Republic of Mari El: Eastern, Orsha-Kokshag and Vetluga-Yushut. Their aboveground, underground and total phytomass of cenopopulations of the studied species were determined, and the content of sum organic substances and carbon in phytomass was calculated. The habitat conditions of the species were studied using the phytoindication method, the data of geobotanical descriptions were analyzed using environmental scales by D. N. Tsyganov (1983) and L. G. Ramensky (1956). Factors affecting the aboveground and below-ground primary production of the studied species (climatic parameters, illumination, moisture content, soil acidity and alluviality, degree of pasture digression) were identified. A favorable effect has been established on the processes of storage of plant phytomass of variably provided dry-fresh meadow humidification, semi-pasture stage of phytocenosis, slightly acidic and very weakly alluvial soils. It was shown that under favorable environmental conditions the total phytomass of Tripleurospermum inodorum (L.) Sch. Bip cenopulations reached 138,76 g/m2 and Leucanthemum vulgare Lam. — 62,65 g/m2.
