Distribution of tiller density and mass of Calamagrostis langsdorffii (Poaceae) in pure stands in Northern Western Siberia

摘要

An attempt was made to interpret peculiarities of distribution of tiller density and mass of Calamagrostis langsdorffii in pure stands. Deviations in distribution of these characters from the normal law were ascertained to coincide more frequently with the highest levels of productivity. The deviations of both characters at the same time occurred very rarely (1 case of 10), and the normal distribution prevailed in general (12 sampling plots of the total 22).
