Outline
In this experiment, seven different camellia plants were used as rootstocks and four different camellia scions to form 28 combinations, to screen the stocks-scion combination and study the grafting affinity, and to measure and analyze grafting experiment indicator that is the survival rate, preservation rate and growth traits of grafted seedlings, to investigate the growth status of grafted seedlings after 18 months. The relationship between grafting anvil, soluble sugar content and graft compatibility was evaluated. The result showed that the grafted survival rate and preservation rate of Camellia gigantocarpa Hu grafted with C. rosmannii and C. achrysantha scion were more than 90%, and the grafting survival rate and survival rate of scions reached more than 80% when C. gigantocarpa Hu grafted with C. chrysantha,, it is proved that C. gigantocarpa Hu is the best rootstock for grafting affinity. The grafting seedlings of C. japonica Heimudan and C. rosmannii had a preservation rate was 6.67%, the preservation rate of C. japonica Heimudan and other 3 kinds of scion was 0, it is proved that C. japonica Heimudan had the worst affinity as rootstock. The scions of C. achrysantha and C. rosmannii had better affinity with different rootstocks. The grafting survival reached more than 90%when C. achrysantha was grafted with C. semiserrata, C. hirsuta, C. japonica Heimudan, C. gigantocarpa. The grafting survival reached more than 90% when C. rosmannii grafted with C. gigantocarpa and C. amplexicaulis. The grafting survival reached more than 80% when C. rosmannii grafted with C. semiserrata and C. polyodonta. Grafting affinity is related to the soluble sugar content of stocks-scion. Closer sugar content of stocks-scion leads to the ratio is closer 1 and the higher grafting survival rate will be. C. gigantocarpa/C. achrysantha, C. hirsuta/C. achrysantha, C. amplexicaulis/C. rosmannii, C. gigantocarpa/C. rosmannii, C. gigantocarpa/C. chrysantha were found to be the excellent combinations by principal component analysis.
