Effect of caging on bee behaviour and pollination efficiency of Apis mellifera on seed production of hybrid sunflower Jr. Vaishampayan S.*, Sinha S.N. I.A.R.I. Regional Station, Kamal 132 001, India * Present Address:- KVK, College of Agriculture, Jaswadi Road, Khandwa (M.P.), India. Abstract The honey bee (Apis melliera) behaviour and its pollination efficiency on sunflower hybrid seed production under different modes of pollination were studied. Caging with nylon mosquito net affected both the bee behaviour and its activity mainly due to differential micro environmental conditions, such as light and relative humidity. There was no effect of caging on air temperature. Per cent seed setting and number of seed per capitulum were at par under open and caged bee polliation conditions when compared with hand pollination. The seed weight was however, significantly low in caged bee and hand pollinated capitula compared to open pollinated capitula. Top | |
