The influence of self, open and cross pollination (with two pollinizers, i.e. Kronaki and Coratina olive cvs.) on fruiting of Picual olive trees were studied during 1997 and 1998 seasons under Giza conditions. Cross pollination significantly gave the highest number of fruit set per meter followed by open pollination, while self pollination ranked latter. Cross pollination with Kronaki pollen was more effective than Coratina pollen. In addition, cross pollination using Kronaki pollinizer showed the heaviest and largest fruits as compared to other pollination treatments. Moreover, Picual trees under cross pollination either by Kronaki or Coratina pollen as well as open pollination yielded fruits with higher dimensions than those resulted from self pollination treatment. Generally, cross pollination gave fruits of oblong shape, while fruits yielded from self pollination tended to have round shape. On the other hand, no significant influence on both flesh/fruit percentage and moisture content was observed according to the different pollination treatments. A slight increase in fruit oil content was recorded under cross and open pollination as compared to self pollination.
