ABSTRACT

It was observed during field investigations that Phleum phleoides show expansive character at some stations. Three populations were selected from 31 stations of the species known from the central-eastern Poland. At each of these stations 10 tufts were chosen randomly in two repetitions: the first in typical grassland, the second in grassland with visible disturbed upper layer of soil (in Bohukały, Mołożew, Popowo Koœcielne). The following parameters were measured: quantity of inflorescences in one tuft, length of each inflorescence shoot and length of each inflorescence ear in investigated tuft. Average values for each tuft and investigated stations were calculated. Obtained results were compared with parameters of typical grasslands in Gnojno and Kisielany and three populations from xerothermic grasslands in southern Poland.

Key words: Phleum phleoides (L.) H. Karst., distribution, population parameters, central-eastern Poland..
