Morphometric differentiation of Carex ligerica Gay in Poland

摘要

The experimental material involved 7 Carex ligerica Gay populations which were cultured in standardised conditions in a greenhouse before their spikes were collected for morphological studies. Four characters reflecting size of male and female glumes, selected from particular spikes were examined. Mahalanobis distances for each pair of populations were calculated and their significance was estimated suing Hotellings t~2 statistics. Dendrite was constructed on the basis of shortest Maha- lanobis distances while Euclidean distances provided grounds for hierarchy grouping.
