Abstract

The structure of variability of morphological features of perennial grass Hordeum brevisubulatum (Trin.)Link has been studied. The biological and ecological features-indicators defining the vitality state of individual andcoenopopulations of species were determined. Biological indicators are the length of the leaf sheath of the third and fourthleaves of the generative shoot and the signs of the generative sphere (inflorescence length, number of nodes and spikeletsin the inflorescence and potential seed productivity). The group of ecological features-indicators includes the number ofdifferent types of shoots in an individual.
