摘　　要：[目的]了解不同蝴蝶兰品种的耐旱性,初步探索蝴蝶兰耐旱性的机理,为国内蝴蝶兰选育引种和优质高效栽培提供理论支持。[方法]选取皇贵妃等8个不同品种蝴蝶兰,采用自然失水法进行干旱胁迫处理,于处理第20天分别测量8个品种的对照组和处理组相关指标,包括地上部分鲜重、地下部分鲜重、地上部分干重、地下部分干重、叶绿素含量等指标。[结果]“光芒四射”的萎蔫叶片比为0.42,在这8个品种中最低,且地上鲜重、地上干重、地上干重与地上鲜重比和地下干重与地下鲜重比均大于1,而“红玛瑙”地下鲜重胁迫指数为0.35,地上鲜重、地上干重、叶绿素含量胁迫指数等均远低于其他7个品种。[结论]在同等干旱胁迫下,“光芒四射”较其余品种表现良好的抗逆性,“红玛瑙”耐旱性较差。[Objective]To understand the drought tolerance of different Phalaenopsis species,to explore the mechanism of drought tolerance of Phalaenopsis,and to provide theoretical support for domestic breeding and introduction of Phalaenopsis and water-saving related applications in production.[Method]Eight different varieties of Phalaenopsis were selected and treated with natural water loss method.On the 20th day of treatment,the relevant indexes of the control group and the treatment group were measured respectively,including fresh weight of the above-ground part,fresh weight of the underground part,dry weight of the above-ground part,dry weight of the underground part,chlorophyll content and other indexes.[Result]The wilting leaf ratio of‘radiant’was 0.42,which was the lowest among the 8 varieties.Aboveground fresh weight,aboveground dry weight,aboveground dry weight to aboveground fresh weight ratio and underground dry weight to underground fresh weight ratio were all greater than 1,and the underground fresh weight stress index of‘red agate’was 0.35,along with the aboveground fresh weight,aboveground dry weight and chlorophyll content stress index were much lower than the other 7 varieties.[Conclusion]Under the same drought stress,‘Radiant’showed better drought resistance than other varieties,‘red agate’showed worse drought resistance.
