摘　　要：以普通油茶本砧嫁接为对照,研究博白大果油茶、广宁红花油茶、香花油茶、陆川油茶与普通油茶优良无性系岑软3号苗期的嫁接亲和性。结果表明:香花油茶作为砧木嫁接岑软3号的成活率及存活率分别达到了91.67%和98.55%,抽梢以及嫁接苗的生长与以普通油茶作为砧木均没有显著性差异,参试的4个物种中香花油茶与岑软3号的嫁接亲和力最好;其次是陆川油茶,嫁接成活率和存活率分别达到了93.67%和95.00%,但嫁接苗生长1年后叶片N、P、K含量显著低于对照;广宁红花油茶在嫁接过程中表现出了一定的不亲和性,嫁接成活率仅为72.00%,且后期生长受到抑制;而博白大果油茶嫁接成活1 a后的存活率仅为24.49%,生长受阻,嫁接后期表现出了明显的不亲和性。Abatract Selected Camellia oleifera as control root stock （CK）, grafting compatibility was studied on C. oleifera Cenruan 3 superior clone scion by using C. gigantocarpa, C. semiserrata, C. osmantha, C. vietnamensis as root stocks in the seedling stage. The results showed that： the graft survival and preservation rate was 91.67% and 98.55% respectively with C. osmantha was used as root stock there were all no significant differences in sprout and growth of grafted seedling, The best grafting compatibility of these four root stocks with C. oleifera Cenruan 3 was C. osmantha; Flowlled by C. vietnamensis, of which the graft survival and preservation rate was 93.67% and 95.00% respectively, but its leaf N, P, K content were significantly lower than the control after growing one year; C. semiserrata showed some incompatibility in the grafting process, of which graft survival rate was just 72.00% and latter growth was inhibited; While the graft preservation rate of C. gigantocarpa was just 24.49% after growing one year and the latter growth was also inhibited, which showed obvious incompatibility.
