8个油橄榄品种果实性状及含油率的比较分析

Comparative Analysis on Fruit External Characters and Oil Content of Eight Olea europaea L. Varieties

[目的]为油橄榄品种选育提供理论依据。[方法]测定比较云南省永仁县8个油橄榄品种的果实性状及含油率。[结果]果实质量变异系数最大(40.79%),果形指数的变异系数最小(8.36%)。鲜果含油率最大的是佛奥(22.77%),最小的是小苹果(12.08%)。[结论]通过各项指标的测定,8个油橄榄品种的果实外部性状有着明显的差异,含油率较高的品种是佛奥、鄂植8号、科拉蒂和米提尼。

[Objective] The paper provided theoretical basis for breeding olive varieties.[Method]The paper was conducted on fruit external characters and oil content of 8 varieties of olive generally cultivated in Yongren county,Yunnan province.[Result] The result indicated that the fruit-weight index variation was the largest（40.79%）.The fruit-shape index variation was the smallest（8.36%）.Frantoio＇s oil content was the highest（22.77%）.And the Manzanilia＇s oil content was lower than the other seven varieties（12.08%）.[Conclusion]From the experiment we can conclude that these 8 varieties had significant differences on fruit external characters.The varieties with higher oil content was Frantoio,EZ-8,Coratina and Adramittini.
