对３个油橄榄品种（Ｃｈｅｔｏｕｉ，Ｐｉｃｈｏｌｉｎｅｍａｒｏｃａｉｎｅ和Ｏｌｉｖｉｅｒａ）开花生物学的研究表明：在盛花期后的第二至第六周间有一幼果脱落高峰，该高峰与幼果从初生长高峰相吻合．这证实的果的大量脱落与果实间的竞争有关．统计结果显示：盛花期各个品种单位花序之结果数相差很大，但收获时这一参数却趋于同一；相反，收获时各品种结实花序的留存率却相差甚大，这说明品种间结实能力差异极大．控制授粉试验表现：品种Ｃｈｅｔｏｕｉ具有一定程度的自花不孕性． Studies on the flowering biology of three olive cultivars (Chetoui, Picholinemarocaine and Oliviera) showed that there was a young off-peak from the second to the sixth week after flowering, which coincided with the growth of young fruits from the beginning of the first growth. This confirmed a large number of fruit loss and fruit competition. The statistical results showed that the number of inflorescences varied greatly among different flowering stages, but the parameters tended to be the same at the harvest stage. On the contrary, there was a large difference in the survival rates of all inflorescences when harvesting. great. Controlled pollination performance: Variety Chetoui has some degree of self-sterility.
