Components of Pollination of Commercial Strawberries in Michigan1

Abstract

Abstract Based upon cage studies with 11 cultivars of strawberry, self-pollination was responsible for 53% achene development, the addition of wind-motion resulted in 67% achene development, and the addition of insect pollination resulted in 91% achene development Insects contributed most to pollination in cultivars with stamens shorter man the receptacles, and least in cultivars with stamens taller. Stamen height was correlated with achene development in primary and secondary flowers in cloth- and screen-covered cages which excluded bees.
