Effect of Honeybee Pollination on Quantity and Quality of Apple Crop in Kullu Hills of Himachal Pradesh, India

The experiment on quantitative and qualitative effects of honeybee pollination on apple crop were carried out on European bee Apis mellifera L. and Indian hive bee Apis cerana F. , by placing two colonies of each species in experimental apple orchards located at Bhalogi (1400 m), Baskhola (1580 m) and Dhamadhar (1810 m) areas in Kullu hills of Himachal Pradesh. There was no significant difference (Pgreater than0.01) in the fruit set in different experimental designs (honeybees pollinated flowers, open pollinated flowers and in control) in self-compatible varieties of apple (Golden Delicious and Red Gold), but the differences in these experimental designs were significant (P0.01). In Golden Delicious and Red Gold, the qualitative pollination data showed that weight, length, breadth, volume and number of seeds per fruit developed were significantly maximum in honeybee pollinated flowers (P
