摘　　要：研究不同品种蝴蝶兰在低温逆境下的生理差异,对不同品种蝴蝶兰的耐冷性进行综合评价,以期为蝴蝶兰抗冷栽培、抗冷品种选育及抗冷生理机理研究提供理论基础。采用逐步降温的方式,观察测定不同低温胁迫下16个蝴蝶兰品种的叶片形态特征及各项生理指标,通过隶属函数法和聚类分析法对16个蝴蝶兰品种进行耐冷性综合评价,并运用灰色关联分析法对各项生理指标与蝴蝶兰耐冷性进行关联分析。结果表明,‘阿里山’、‘花样年华’、‘婚宴’、‘一见钟情’、‘富乐之星’、‘1372’属于强耐低温品种;‘大辣椒’、‘蜡红花’、‘黑闪电’、‘满天红’、‘5064’属于中耐低温品种;‘黄金甲’、‘红蝴蝶’、‘红冠天’、‘wk1753’、‘冰山美人’属于弱耐低温品种。Fo、Fm、Fv/Fm、叶绿素含量、相对电导率、SOD与CAT活性以及MDA含量都与蝴蝶兰耐冷性关系密切,可作为蝴蝶兰耐冷性鉴定指标。By studying the physiological differences of various species of Phalaenopsis under low temperature stress,and comprehensively evaluating their cold tolerance,the paper aims to provide a theoretical basis for Phalaenopsis cold-tolerant cultivation,cold-tolerant cultivar breeding and the research on its physiological mechanism of cold tolerance.The gradual cooling method was adopted to observe and determine the leaf morphological characteristics and various physiological indexes of 16 Phalaenopsis cultivars under different low temperature stress.The cold tolerance of the 16 Phalaenopsis cultivars was comprehensively evaluated by the subordinate function method and the cluster analysis method.The correlation between various physiological indicators and the cold tolerance of Phalaenopsis was analyzed using the grey relational analysis method.The results show that‘Alishan’,‘In the Mood for Love’,‘Wedding Promenade’,‘Love at First Sight’,‘Fule Star’and‘1372’are strong low-temperature tolerant cultivars;‘Big Chili’,‘Wax Red Flower’,‘Black Lightning’,‘Red Sky’and‘5064’are medium low-temperature tolerant cultivars;‘Golden Armor’,‘Red Butterfly’,‘Red Crown Sky’,‘wk1753’and‘Bingshan Beauty’are weak low-temperature tolerant cultivars.Fo,Fm,Fv/Fm,chlorophyll content,relative conductivity,SOD and CAT activity,and MDA content are all closely related to the cold tolerance of Phalaenopsis,and could be used as identification indicators.
