Coenopopulation Alopecurus arundinaceus (Poir.) state under conditions of Lena-Viluy interfluve

For the first time the structure of morphological parameters variability, correlation between them and evaluation the state of coenopopulation (CP) Alopecurus arundinaceus Poir. by organism and population parameters under conditions of Lena-Viluy interfluve (Yakutia) have been studied. As a result it was re-vealed 4 indicator groups: ecological-biological, biological, genotypical (taxonomical), and ecological. The largest portion of realized significant correlations between morphological parameters was recorded for CPs 3, 5, 6 and 7. Evaluation of organism and population parameters proved the best state of CPs 6 and 7.
