| Abstract: | [Objective] Solve the problems of low survival rate and varieties update high cost of Camellia oleifera.[Method]Different of grafting time,thickness of rootstock,grafting method,maturity of the scion on survival rate of Camellia oleifera were studied.[Result] With 4-6 cm diameter branches as rootstocks,scion was born with pumping half lignified branches with green leaf,side grafting from mid May to early June,grafting survival rate reached 94%.[Conclusion] The research results can access grafting success in 1 year and reduce the cost of reconstruction varieties |
