Abstract The flower structure of the ‘Delicious’ apple ( Malus domestica Borkh) differs from that of most apple cultivars by having gaps at the base of stamens. Honey bees ( Apis mellifera L.) learn to collect nectar through these gaps and avoid the flowers’ sexual parts; consequently, visits to ‘Delicious’ are less than half as effective in pollination as are visits to other cultivars.
