摘　　要：系统观测12份澳洲坚果Macadamia spp.种质的开花物候期,分析其开花物候期的变异规律,并根据物候变异划分物候类型。结果表明:不同种质的开花物候期存在不同程度的变异,变异系数为6.73%~38.07%。进入花芽萌动期、花序抽生期、开花期、谢花期的时间差分别为32、24、23、14 d。所调查的种质花序开放顺序是从花序基部先开始,向顶端依次开放。不同种质的开花批次、花序长度、花朵颜色、花多数量存在不同程度的差异。通过聚类分析可将12份澳洲坚果种质分为4类,主成分分析第一主成分、第二主成分累计贡献率为71.199%。The blooming Phenophase of 12 Macadamia spp.was systematically observed,the variation of the blooming phenological period was analyzed,and the phenological types were divided according to the phenological variation.The results showed that there were different degrees of variation in blooming Phenophase of different germplasm,and the coefficient of variation was 6.73%-38.07%.The time difference between entering the flower bud sprouting stage,inflorescence sprouting stage,flowering stage,and deflorating stage was 32,24,23,and 14 days respectively.The inflorescence opening sequence of the investigated germplasm was from the base of the inflorescence to the top.There were different degrees of variation in flowering batch,inflorescence length,flower color,and number of flowers in different germplasm.Twelve Macadamia spp.germplasm could be classified into four categories by cluster analysis.The cumulative contribution rate of the first and second principal components of principal component analysis is 71.199%.
