摘　　要：选择闽侯桐口林场油茶杂优F1代5个杂交组合,按造林苗木分级标准,同时视成活苗木具体数量将不同杂交组合的苗木分为3或4个等级,进行造林对比试验。在造林18年后的2003、2004、2005和2007年进行生长量调查,并对逐年树高、冠幅乘积和产果量进行方差分析和相关分析,结果表明:不同等级的苗木,对造林18-22年的生长量差异影响不显著,苗木分级与树高、冠幅乘积和产果量的相关性也不显著。According to seedling grading standards, 5 hybrid combination seedlings of Camellia oleifera F1 generation in Tongkou forestry farm had been divided into four grades or three grades by the seedling survival number of combinations, which was for the planting contrast test. 18 years later, according to the data of five successiv6 years＇ （except the missing data in 2006） growth, the different grades of tree height, crown product, fruit yield in four years were analyzed through variance analysis and correlation analysis. The results showed that different grades of seedlings did not significantly affect the growth of C. oleifera in 18 - 22 years, and tree height, crown product, fruit yield were not relevant remarkably with grades of seedlings.
