Abstrakt
Gentiana cruciata is a protected species which appears relatively rarely in xerotermic
communities. The research on the population of this species was carried out in 2006. Number of
specimens, density and spatial structure were examined on 5 × 5 m experimental areas.
Floristic composition of phytocoenoses were characterized, too. In Kamieniec and Nawodna the
population of Gentiana cruciata was found in Adonido-Brachypodietum pinnati communieties for
which Gentiana is characteristic species. In Nawodna it is estimated on 1370 specimens. The
greatest population of Gentiana cruciata appears on this area and its characteristic feature is
the diversity of length of stems and the number of flowers. The numerous population from
Kamieniec is characterized by the changebility of biometric parameters because of diversified
habitat conditons. The population from Zdroje takes up the smallest area (106 specimens)
where the most frequent blossoming was marked. The part of blossoming specimens was
smaller because the worsening of light conditons. The aggregate type of spatial distribution was
found in all examined populations.
