ABSTRACT

The population variability of Beckmannia eruciformis was investigated on the basis of measurements of 10 biometric features: total height of grass, height of culm, height of leafless culm, length of inflorescence, number of 1st rank ramifications in inflorescence, length of the lowest ramification in inflorescence, length of top spikelet, number of leaves, length of the largest leaf, width of the largest leaf. Studies were carried out in 2006 at five localities situated in central eastern Poland – Bagno Pulwy, Grębków, Siedlce, Zabuże and Bereza. The maximum, minimum, arithmetic mean and range were calculated for each feature. Populations of Beckmannia eruciformis differed significantly in all of the investigated features (Tukey’s test, significance level 0.95). Specimens occurring in natural, well supplied with water habitats in localities Zabuże and Bereza were characterized by the highest mean values of morphological features. A water supply during whole vegetation period is probably the main factor affecting studied morphological differences and condition of specimens. The only exception was the longest top spikelet calculated for the population in Siedlce.

Key words: Beckmannia eruciformis, Poaceae, population variability, central-eastern Poland.
