摘要：采用髓心形成层对接法对马占相思及其杂种优树开展嫁接研究 ,结果表明 :优树的基因型对于嫁接结果具有显著影响 ,杂种无性系平均嫁接成活率达 82 % ,高出纯种无性系 2倍 ;嫁接季节对接活率有很大影响 ,春季接活率为 76.9%～ 82 .0 % ,分别比夏季、秋季提高 130 %、190 %以上 ,冬季嫁接成活率很低 ;砧木地径以 0 .5～ 0 .8cm为佳 ,接口高度 30～ 4 0 cm为优 ,接穗以具有 4～ 5个腋芽的穗段为优。
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.
