| 中文摘要: |
| 观测广东湛江地区21份澳洲坚果种质资源成年树的抽梢物候期及枝梢生长特性,分析其抽梢物候期及枝梢生长的变异规律,并根据枝梢生长差异划分枝梢类型。结果表明：澳洲坚果成年树全年主要抽春、夏、秋梢,不同种质的春、夏、秋梢的抽梢物候进程存在明显差异,变异系数为20.2%~78.1%；不同种质的春、夏、秋梢的枝梢长度、节数、节间长度也存在不同程度的差异,变异系数为16.6%~35.6%；聚类分析将澳洲坚果种质分为枝梢生长特点各异的3 类,即短枝少节型、中枝少节型和长枝多节型。 |

| The shooting phenophase and growth characteristics of 21 macadamia germplasm resources from Zhanjiang, Guangdong were investigated, analyzing variation, dividing shoots types according to the the shoot growth differences. The results show that macadamia mature trees mainly shoot in spring, summer and autumn throughout the year, The shooting phenophase of spring shoot, summer shoot and autumn shoot greatly differed among all tested germplasm resources with variation coefficient of 29.9%-78.1%. The shoot length, node number and internode length of spring shoot, summer shoot and autumn shoot were also obvious diversities with variation coefficients of 16.6%-35.6%.SThree shoot types of macadamia germplasm resources were classified by cluster analysis, namely short branch with few nodes, middle branch with few nodes and long branch with many nodes. |
