Impact de la pollinisation par les abeilles (Apis mellifera Linné) sur la production de pommes, CV Jonagold.

With an aim to analyse the quantitative impacts of insect pollination, experiments were carried out by comparing several types of pollination with or without honey bees (Apis mellifera LINNE) on apple (cv Jonagold) at Vise, Belgium. Allopollination seems to be indispensable (5\% of fruits set by autopollination without honey bees, and 40\% of fruits set by allopollination). However, it is also found to be partially autocompatible as 20\% fruit setting was done by autopollination with honey bees.
