| 摘要: |
| 红厚壳（Calophyllum inophyllum）是热带地区多功能的优良树种。为筛选出适宜的红厚壳嫁接 技术，研究采用完全随机区组设计，设置了不同嫁接方式、穗条类型、穗条存放时间等3 因素不同水平 的嫁接试验，分析不同嫁接处理组合对成活率和抽芽数的影响。研究结果表明：劈接、合接、切接3 种 不同嫁接方式中切接的成活率最高，显著高于合接和劈接；半木质化穗条比木质化穗条嫁接成活率高3.5 个百分点，差异未达到显著水平；穗条存放0~2 d 后嫁接的成活率显著高于存放3 d；利用存放2 d 的半 木质化穗条进行切接，抽芽数最多，达到3.9 个。综合分析，采用半木质化穗条存放0~2 d 后进行切接有 利于提高红厚壳嫁接的成活率。 |

| Abstract: |
| Calophyllum inophyllum is a multifunctional tree species, naturally distributed in tropic area. In order to screen out suitable grafting technology of C. inophyllum, and to provide reference for strengthening resource conservation and cultivation on this species, a grafting experiment was conducted with different grafting methods, cutting types, and storage time of cuttings by adopting completely randomized block design to analyze the effects of different grafting treatment combinations on survival rate and the number of cion budding. The results showed that the survival rate of the cutting grafting was the highest among the three different grafting methods, which was significantly higher than the other two methods. The survival rate of the semi-lignified cuttings was 3.5% higher than that of the lignified cuttings, but the differences between the two cutting types didn’t reach a significant level. The survival rate of the graftings stored for 0~2 days was significantly higher than that of those done for 3 days. Cutting grafting with semi-ligni?ed cuttings kept for 2 days led to the highest budding number, which was 3.9. It was concluded that cutting grafting with semi-ligni?ed cuttings stored for 0~2 days was advantageous in increasing the survival rate of the graftings of C. inophyllum. |
