| Abstract [eng] |
The genus Pulsatilla includes perennial plants of the Ranunculaceae family. In Lithuania this genus is represented by two species and one hybrid: P. patens, P. pratensis and P. ×wolfgangiana. P. patens is endangered throughout Europe and is included into the Red Data Books of almost all European countries. Endemic species of Europe P. pratensis is included into the Red Data book just in several European countries. P. ×wolfgangiana is very rare hybrid species, occurring in areas where both parental species occur together. The aim of this work was to estimate composition and state of populations of the genus Pulsatilla in Lithuania. The tasks of the work are as follows: 1) to reveal plant communities in which members the genus Pulsatilla grow; 2) to evaluate structure of populations according to stages of plant maturity; 3) to investigate density of P. patens and P. pratensis individuals in populations; 4) to compare variation of Pulsatilla morphological characters and their dependence on habitat conditions; 5) to evaluate optimum habitat conditions for Pulsatilla populations in Lithuania. Results of the research enable to reveal composition and state of populations of the genus Pulsatilla in Lithuania and to prepare recommendations for management of their habitats. |
