Graft Compatibility of Camellia oleifera Cenruan 3 Clone
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% and98.55% 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 3was C. osmantha; Flowlled by C. vietnamensis,of which the graft survival and preservation rate was 93.67% and95.00% 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.
