Research on Grafting Techniques of Superior Acacia mangium and Its Hybrid
- Received Date: 2000-01-19
Abstract: The method of medullary cambium grafting was used to study the grafting of superior Acacia mangium and its hybrid. The results showed that the genotype of superior clone had great influence on the grafting. The average grafting survival rate of hybrid clone was over 82%, which was two times that of the pure clone. The grafting was obviously affected by the season. The survival rate of grafting was 76.9%~82.0% in spring, which is 130% and 190% higher compared with that in summer and autumn, while the survival rate of grafting in winter is rather low. The optimum base diameter of stock for grafting is 0.5 cm to 0.8 cm, the grafting height should be 30 cm to 40 cm and the scion with 4~5 axillary buds should be selected.
