| 摘 要： | 系统观测21份澳洲坚果种质资源的开花结果物候期，分析其开花结果物候期的变异规律，并根据物候差异划分物候类型。结果表明：不同种质的开花结果物候期存在不同程度的差异，变异系数为2.91％～37.23％，进入花芽萌动期、花序抽生期、开花期、谢花期、果实膨大期、油份积累期及果实成熟期的时间分别相差约45、43、41、38、30、28、30 d；聚类分析将澳洲坚果种质资源分为物候期特点各异的3类；主成分分析第1、2主成分解释的总变异为 91.985％，更为直观展现了澳洲坚果种质开花结果物候期特点，其结果与聚类分析基本一致。

| Abstract: | The blooming and fruiting phenophases of 21 Macadamia spp. germplasm resources were observed systematically to analyze the phenological variation and to divide the phenological types according to phenological differences. The results showed that the blooming and fruiting phenophases had a large variation among all tested germplasm resources with variation coefficient of 2.91%-37.23%.The time difference of flower bud sprouting stage, inflorescence elongating stage, blooming stage, flower wilting stage, fruit expanding stage, fruit oil accumulation stage and fruit maturity stage was 45, 43, 41, 38, 30, 28 and 30 d, respectively. Three phenological types of Macadamia spp. germplasm resources were classified by cluster analysis. The results of principal component analysis indicated that the first and second principal components could explain 91.985% of total variance, directly demonstrating the characteristics of blooming and fruiting phenophases. The results were basically consistent with that of the cluster analysis. |
