| 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：① 4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”. |
