优树选择;果形指数;籽粒数;冠层高度
摘  要：
利用数理统计分析方法,对我省油茶优树选择中获得的数据进行分析研究,探讨油茶优树选择的几个关键因子与我们选择目标的关系。结果表明,立地条件较差的优树复选概率大于立地条件好的,叶面指数在1.2～3之间的复选入选概率大于其它范围;果形与鲜出籽率呈显著负相关关系,果形指数小于1.1的和单果籽粒数小于3单株有较大几率获得较高的鲜出籽率;冠层高度大于3m的对象有较大几率获得较高单位冠幅面积产果量。

摘  要：
Using the mathematical statistical method,the paper analyzed the data obtained from Camellia oleifera plus tree selection in Guizhou province and probed the relationship between the several key factors of Camellia oleifera plus selection and selection targets.The results showed:the probability of multi-selection of the superior tree having bad land occupation condition is greater than the good land occupation condition.The probability of multi-selection of the foliage index in 1.2～3 is greater than any other scopes.The shape and fresh seed rate existed obvious negative correlation-ship.The single plant whose slope index is less than 1.1 and the grain number is lower than 3.0 is much more fresh seed rate.The plant whose canopy is more than 3m had comparatively large probability to get the upper output of fruit per canopy area.
