BLUEBERRY (V. CORYMBOSUM L.) POLLINATION WITH PRESENCE OF BOMBUS SP.
Honeybees are (Apis sp.) typically the most important commercial pollinators of the insect pollinated fruits including highbush blueberries (Vaccinium corymbosum L.). However since blueberries are native to North America where there are no native honeybees and they are pollinated in the wild mostly by bumblebees (Bombus sp.), there is some discussion as to whether commercial bumblebee hives would be more useful in commercial plantings. One honeybee hive was placed in the experimental plot, and it was observed that the honeybees visited the blueberry flower for a short period of time and did not enter the flower. In contrast bumblebees from commercial hives placed in the plot visited flowers for longer periods of time. In the agricultural production areas of Brezovicë (1043 m) and Llukë e Epërme (490 m), in Kosovo during 2008-2010, we studied honeybee vs. bumblebee pollination in the first highbush blueberry planting in Kosovo. Previously we had studied the various phonological stages for blooming in comparison with honeybee and bumblebee visitation. In addition, the shape and dimensions of the flower, the fruit mass, and the seed numbers per fruit was determined for several cultivars including: Duke, Elliott, Legacy, Spartan, Chandler and Bluecrop.
