| Abstract:
In self-sterile apple, plum and sour cherry cultivars even partial limitation of the duration of the bee pollination period significantly reduced fruit set and yield. Limitation resulted in a strong reduction for apple cultivars and for 1 self-sterile sour cherry cultivar even if bee pollination was prevented from the 5–6th day after the onset of blooming only. In 1 self-sterile plum cultivar, however, moderate limitation was not of significant influence but strong or complete limitation again resulted in a strong reduction of yield. As found for sour cherry self-fertile cultivars can be sensitive to very strong or complete limitation of bee pollination, but other self-fertile crops or cultivars hardly respond or don't respond at all to the limitation of bee pollination (e.g. plums in the present study). Yield seems to be a more reliable criterion than fruit set when evaluating the sensitivity of cultivated plant species or cultivars to the limitation of the duration of the bee pollination period. | |
