摘　　要：以‘16136’蝴蝶兰为试材,采用统计分析法,研究不同苗龄蝴蝶兰形态指标与开花性状的相关性,以期建立一个外观质量鉴定标准,从形态特征预测花朵性状,提前对实生苗进行选择,从而缩短育种周期。结果表明:苗龄6个月的‘16136’蝴蝶兰(T1)长至苗龄12个月(T2)时形态指标、开花性状均没有显著的变化,在T2长至苗龄18个月(T3)时各指标发生了极显著的变化。蝴蝶兰形态指标和开花性状之间有显著的相关性。T1蝴蝶兰的株高、最大叶宽、叶片数与其开花性状有显著相关性;T2蝴蝶兰的最大叶长、最大叶厚、叶片数与其开花性状有显著相关性;T3蝴蝶兰的株高、最大叶长、最大叶宽与其开花性状有显著相关性。因此,蝴蝶兰在不同苗龄催花时,可根据形态指标与开花性状的相关性预测其花横径、花纵径、花梗数、花序长、花梗数等。Taking Phalaenopsis aphrodite‘16136’as the test material,statistical analysis was used to study the correlation between morphological indicators and flowering characteristics of Phalaenopsis aphrodite at different seedling ages,in order to establish an appearance quality identification standard,predict flower characteristics from morphological characteristics,select seedlings in advance,and shorten the breeding cycle.The results showed that there was no significant change in morphological and flowering characteristics of the Phalaenopsis aphrodite‘16136’(T1)at 6months of seedling age until 12months of seedling age(T2).However,significant changes were observed in all indicators from T2to 18months of seedling age(T3).There was a significant correlation between morphological indicators and flowering traits of Phalaenopsis aphrodite.There was a significant correlation between the plant height,maximum leaf width,and leaf number of T1 Phalaenopsis aphrodite and their flowering characteristics.There was a significant correlation between the maximum leaf length,maximum leaf thickness,and leaf number of T2 Phalaenopsis aphrodite and their flowering characteristics.The plant height,maximum leaf length,and maximum leaf width of T3 Phalaenopsis aphrodite are significantly correlated with their flowering characteristics.Therefore,when promoting flowering of Phalaenopsis aphrodite at different seedling ages,the correlation between morphological indicators and flowering traits can be used to predict their flower transverse diameter,flower longitudinal diameter,number of flower stems,inflorescence length,and number of flower stems.
