Wild bees as pollinators of four Gentiana species of Mount Vitosa (Bulgaria)
Bumb1e-bees (Bombus species) are the most effective and thus the main pollinators of Gentiana lutea, G. punctata and G. asclepiadea. Gentiana cruciata is pollinated by bumble-bees and Halictus bees. The flower constancy of the pollinators is high.
