摘　　要：在金华市东方红林场浙江红花油茶(Camellia chekiangoleosa Hu.)种质资源圃内设点调查,对12个浙江红花油茶无性系树体性状变异及其性状之间的相关性进行了研究。结果表明,浙江红花油茶树体在无性系间存在显著的差异,12个无性系树体总体变异系数最大的是地径(变异系数为10.16%),其次为冠形指数(变异系数为6.98%)和冠幅(变异系数为6.68%),树高的变异系数最小(变异系数为6.03%)。12个无性系树高、冠幅、地径、冠形指数变异系数最大的分别是hy44、ny2、hy30、hy44,分别为12.16%、13.20%、22.05%、13.89%。浙江红花油茶树高、冠幅、地径相互间极显著相关,不同无性系树高与冠幅之间呈显著的线性相关,即随着树高的增大,树冠也随之增大。The survey of tree growth traits of Camellia chekiangoleosa Hu. was collected from Dongfanghong Tree Farm of Jin- hua City. The variation and relativity of tree growth traits were studied. The results showed that tree growth traits of C. chekiangoleosa Hu. had huge differences among different clones. The greatest variation in total was ground diameter （CV= 10.16%）, followed by index of the crown （CV=6.98%）and crown diameter （CV=6.68%）. The least variation was tree height （CV=6.03%）. The greatest variations on tree height, crown diameter, ground diameter , index of the crown of C. chekian- goleosa Hu. clones were hy44 （12.16%）, ny2 （13.20%）, hy30 （22.05%）, hy44 （13.89%）, respectively. There were significant correlation between tree height, crown diameter, ground diameter of C. chekiangoleosa Hu.. Great linear correlation was found between tree height and crown diameter. With the increase of tree height, crown diameter was increased.
