摘　　要：为了筛选出适合高温条件下生长的月季品种,选定7个具有一定耐热性的品种绯扇、冰山、蓝斯带、香欢喜、红双喜、香水黄和芝加哥和平,通过在深圳高温的温室条件下栽培和鉴定,研究常温和高温对月季品种形态和生理指标的影响。结果表明:在形态方面,7个月季品种高温下,生长比较缓慢,冰山和绯扇的生长相对较好,开花数量和开花质量也较好,而香水黄和芝加哥和平在高温下生长缓慢,不开花;在生理方面,随着温度升高,7个品种均表现为MDA含量增加、SOD活性上升、脯氨酸含量也随温度升高呈增加趋势,高温下耐热性强的品种能保持更高的SOD等保护酶活性和更低的MDA含量,并诱导产生更多的脯氨酸。In order to filter out the variety which could grow suitably in the high temperature, seven varieties with certain heat resistant were selected including Feishan, Iceberg, Blue ribbon, Xianghuanxi, Double delight, Xiangshuihuang,Chicago peace,through the cultivation and identification in the conditions of high temperature in greenhouse located at Shenzhen,some morphological and physiological indicators were measured under nor- mal and high temperatures. The results showed that：in morphology,seven rose varieties grew slowly under the high temperature,Iceberg and Feishan grew better than others, manifested in the number of flower and the quality of flowering,but Xiangshuihuang and Chicago peace grew the most slowly and had no flower~ in the physical aspects,as the temperature increases, seven varieties showed an increase in MDA content, SOD activity and proline content,in the high temperature the heat resistant varieties could maintain higher activity of SOD, lower MDA content and induce more proline.
