Behaviour of honey bee, Apis indica on cauliflower and their pollinating effect on seed yield [in Bangladesh]
1987
Alam, M.Z.
Replicated caged plots of three varieties of cauliflower (Aghrahani, Poshali and Patnai variety of Bangladesh) were used to study the behaviour of honey bee and their pollinating effect on seed production. Irrespective of varieties a honey bee visited ca 203 flowers (on the basis of 18 days observations) during its visiting hour in a day and spent ca 7 seconds per flower. A significantly higher percent of filled seeds were resulted only in Poshali variety where honey bee pollinated flowers produced 68.7% filled seeds compared to naturally pollinated flowers (54.2%). Only 24.6% filled seeds were produced in control plots where no pollinators were allowed. No significant differences were found in pod size among three varieties, pollinated naturally or by honey bees or without pollinators (control). The mean weight of 1000 seeds in all varieties were similar irrespective of treatments. Number of seeds per pod in all three varieties were always tend to be higher in naturally pollinated cauliflowers followed by flowers pollinated by honey bee and flowers without pollinators (control).
