Fitocoenotice an arrangement and ontogenetic structure coenopopulations Solidago virgaurea L. in national park «Mari Chodra»

The article describes the analysis of 15 cenopopulations of Solidago virgaurea L. in the National Park «Mari Chodra». Has shown, that the greatest ecological possibilities of this species are realized by the scale of the saline regimen of soils Tr – 59 %. The basic twin-cone spectrum with maximum in the group of species in middle-aged generative condition and local maximum in the group of grown-up vegetative plants is typical for these cenopopulations. The density of cenopopulations depends on the stages of its development and it is maximal in the young normal cenopopulation (ЦП 12 – 32 шт/м 2), but if it is senescent normal (ЦП 6 – 9,2 шт/м 2), one it is reduced in 3,5 times. By the classification of L.A. Givatovsky from 15 normal cenopopulations there are 8 young, 2 ripen, 3 mature, 1 ageing and 1 transitional cenopopulation.
