摘要: 以20份月季(Rosa chinensis Jacq.)资源枝条为试验材料, 利用人工气候室进行枝条发芽试验, 结合品种成活率, 研究了各品种的耐寒性。结果表明, 爱、巴黎铁塔、粉扇、天堂、新勇敢5个品种完全冻死, 不能在辽阳及以北地区绿化应用;哈德福俊、花魂、橘红火焰、天山祥云、宇多野5个品种在辽阳最低气温-25.2 ℃条件下完全成活;安吉拉、万岁、修母主教、伊丽沙白女王4个品种, 虽地上部受冻, 但地下部未受冻, 依然能够成活。低温下枝条失水率从宏观上可以作为月季耐寒性的判断指标, 本研究筛选成活的9个品种具有一定的耐寒性, 为今后在北方城市绿化中推广应用提供了依据。

Abstract: Twenty rose varieties were collected to analyze cold resistance according to germination test by using cutting branches, combined with survival rate under natural conditions with temperature change. The results indicated that five varieties of Love, Eiffel Tower, Fen Shan, Paradise, New Spartan were entirely frozen to death, which were not suitable for landscaping application in north area or Liaoyang, Liaoning province. Otherwise, Hadefujun, Chivalry, Orange Fair, Tianshan Xiangyun, Utano were survived under -25.2 ℃ in Liaoyang. Angela, Viva, Cardinal Hume, Queen Elizabeth were frozen in overground part, but still can survive because of not frozen in underground part. The rate of water loss at low temperature can be used as a macro index to evaluate the cold resistance in rose. In the study, nine rose varieties were selected with a certain cold-resistance, which can be provided for foundations on city landscape of north area in the future.

Key words: rose(Rosa chinensis Jacq.), branch germination, cold resistance, wintering survival, water loss of branches
