Effect of ‘Hongluzhen’ Camellia on Grafting of Camellia chrysantha

【Objective】To study the effect of‘Hongluzhen’camellia as stock on grafting of Camellia chrysantha, and to provide reference for propagation of high-quality grafting seedlings of C. nitidissima.【Method】 Five varieties of C. oleifera, tea tree and Camellia were used as stocks to graft C. chrysantha and the most suitable stock variety‘Hongluzhen’camellia was selected，and then‘Hongluzhen’camellia was taken as the research object to study the effects of different planting years, different grafting methods and different grafting time on C. chrysantha grafting.【Result】Among the 5 varieties of C. oleifera, tea tree and camellia, the best stock for C. chrysantha was‘Hongluzhen’camellia, followed by C. crapnelliana and C. polyodonta; When C. chrysantha was grafted with‘Hongluzhen’camellia as stock, the survival rate of‘Hongluzhen’camellia grafted with C. chrysantha from 1 year to 5 years old was maintained at 92.5% to 96.4%, with no significant difference, the average shoot length increased with the planting years of stock from 6.8 cm to 18.3 cm; when different grafting methods were used for grafting, the survival rate of skin grafting and the average length of new shoots were the best; As to grafting time, the survival rate of spring and autumn grafting is significantly different from that of summer and winter, and spring grafting is the best, followed by autumn.【Conclusion】When taking‘Hongluzhen’camellia as stock grafting C. chrysantha, it is recommended to choose 2-3 years old stock seedlings grafting in spring with skin grafting method.
