摘　　要：为给良好树形结构的设定及产量预测提供参考,根据2003～2005年闽侯桐口林场的油茶杂交F1代试验林连续3a的生长量调查数据,对49个处理的树高、冠幅、单株产果量的平均数据进行相关性分析和主成分分析。结果表明冠幅与单株产果量间存在显著相关性。对两者进行一元非线性回归模型分析得到回归曲线和回归方程,进一步了解两者间的相关性,同时作出产果量的预测。In order to provide reference for setting fine tree shape and predicting yield, the mean tree heights, crowns and fruit yieJds per plant of 49 treatments were analyzed by correlation analysis and principal component analysis, based on the investigation data of growth increment of F1 generation forest in Camellia oleifera at Tongkou forest farm from 2003 to 2005. The results showed that there was significant correlation between crown and fruit yield per plant. The regression curve and equation were gain by monadic non-linear regression model. Fruit yield could be forecasted and the relationship between crown and fruit yield had been learned.
