| Abstract:
Pollination is one of the most important factors for a good productivity. The choice of the pollinator is based on our knowledge of its capacity to fertilise the variety that has to be pollinated. The aim of this study is to evaluate the efficiencies of different pollinators for sixteen varieties cultivated in France and to compare them with the results obtained in case of free pollination that can occur in a multivarietal field. Trials were carried out in an olive collection of 20-year-old trees at the INRA station near Montpellier. The trees were artificially pollinated and the fruit set was observed 40 days after full blossoming. Varieties have been divided into three categories regarding their level of self-fertility: highly self-incompatible, partially self-compatible, self-compatible. Pollinators have been classified in function of their efficiency of fertilisation for each variety to pollinate: bad pollinator, passable pollinator, good pollinator. In practice, the table obtained will be useful for the producer when he will have to choose pollinators for the varieties studied here. | |
