Effect of habital conditions on population-biological parameters of Hordeum brevisubulanum (Trin.) Link coenopopulations under conditions of the Lena-Viluy interfluve

The effect of ecological factors on population-biological parameters of Hordeum brevisubulatum coenopopulations in the Lena-Viluy Interfluve has been studied. It was revealed that moisture conditions of habitats of the studied coenopopulations vary from dry meadow (53-63 grades) to wet meadow (77-88 grades). The degree of anthropogenic influence varies from light to moderate. Most optimal conditions for development of coenopopulations are observed in mesophytic meadows on rather saline soils under minimal anthropogenic load.
