| Abstract: | This study deals with the pollination ecology of a population Gentiana cruciata in the Vitosha Mts., SW Bulgaria. Fortyeigth % of flowers bagged at bud stage developed into fruits. Flowers in the investigated population was visited actively by insects. Halictus bees constituted 34.5% of all insect visits. Visits by bumblebees (mainly Bombus hortorum) constituted 18.9% of all insect visits. All open-pollinated flowers set fruit capsules and their seed set was high. The pollination biology of this population (at the south-westem part of the distributional range of the species) is compared to that of populations in The Netherlands (at the north-western margin of the distribution range of the species). |
