| Abstract: |
| 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”. |
