摘　　要：采用盆栽试验,运用模糊隶属法,综合比较研究了"夏令营"、"欢藤"、"西方大帝"、"莫扎特"4种藤本月季(Rosa Chinensis)的抗旱性强弱。结果表明在干旱胁迫下:①4个品种的保水力和抗脱水能力的强弱依次为"欢藤">"夏令营"、"西方大帝">"莫扎特"。②"莫扎特"的相对电导率分别比"西方大帝"、"夏令营"和"欢藤"增加19.7%、19.6%和24.0%,且"莫扎特"的丙二醛含量均显著高于其它品种(P<0.05)。③"欢藤"的脯氨酸和可溶性总糖含量显著高于"夏令营"和"莫扎特"(P<0.05)。④"欢藤"的叶绿素含量分别比"莫扎特"和"西方大帝"高43.3%和19.8%。⑤模糊数学隶属函数法综合评价结果:抗旱性强弱为"欢藤">"夏令营"、"西方大帝">"莫扎特"。Pot was employed to study the drought resistance of four climbing rose（Rosa Chinensis） cultivars（＂Summer camp＂,＂Jubilation＂,＂Western emperor＂,＂Mozart＂）.The results of the study revealed that under the drought stress： ① The holding water and retention capability decreased in the order of ＂Jubilation＂,＂Summer camp＂,＂Western emperor＂,and ＂Mozart＂.② The relative electricity conductivity of ＂Mozart＂ was 19.7%,19.6% and 24.0% higher compared with that of ＂Western emperor＂,＂Summer camp＂,and ＂Jubilation＂ respectively,and the MDA content of ＂Mozart＂ was significantly higher than that of others（P〈0.05）.③ The Pro and WSD content of ＂Jubilation＂ were significantly higher than those of ＂Summer camp＂ and ＂Mozart＂ respectively（P〈0.05）.④ The chlorophyll content of ＂Jubilation＂ increased 43.3% and 19.8% respectively compared with that of ＂Mozart＂ and ＂Western emperor＂.⑤ The drought resistances of 4 cultivars were comprehensively evaluated by subordinative function method,and their drought resistances were shown to decrease in the order of ＂Jubilation＂,＂Summer camp＂,＂Western emperor＂,and ＂Mozart＂.
