Botanico-geographycal research of Poa glauca Vahl (Poaceae)
Marina V. Olonova, Robert J. Soreng, Smithsonian Institution
Abstract
The distribution of the Poa glauca aggregate has been specified and a digital map of its distribution has been compiled. An analysis of quantitative characters using the principal component analysis was carried out and a comparison of the frequencies of the states of some qualitative character states were undertaken to identify the morphological homogeneity of the three Eurasian races. These studies did not reveal differences in quantitative traits, but found differences in the frequencies of qualitative traits. These differences may be caused by hybridization with different native species.
