摘要
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.
A study has been made of the florscent biology of three Olea europaea varieties (Chetoui,Picholine marocaine and Oliviera).Results indicate that between the second and the sixth weeks after plenary inflorescence,there is a peak of young fruits droping,which coincides with that of initial growth of young fruits. The fact above Proves that the droping of young fruits is relative to the competitions among young fruits. The statistic results show that in plenary inflorescence,the three varieties differ greatly from one another in number of fruits per inflorescence, but they tend to the same value at harvest. On the contrary,the reservation rates of fertilized inflorescences at harvest differ greatly among the three varieties,which shows great differences in their abilities of bearing. In addition,an experiment of contralled pollination verifies that the variety'Chetoui' possesses selfpollinated in fertility to some degree.
