摘要: 以14种切花月季品种为供试材料,研究其耐低温胁迫性,以期为切花月季冬季生产和耐寒品种选育提供依据。5、0、-5、-10 ℃的低温条件下处理一年生扦插苗,测定其丙二醛(MDA)含量、可溶性糖含量、可溶性蛋白质含量、脯氨酸含量、过氧化物酶(POD)活性和超氧化物歧化酶(SOD)活性,在此基础上,使用隶属函数法计算隶属函数值,并根据综合隶属函数值进行系统聚类分析。结果表明,14种切花月季品种抗寒性差异较明显,抗寒性为影星>坦尼克>蓝月>梅朗口红>卡罗拉>肯尼迪>蓝色香水>还珠>莱茵黄金>金凤凰>白圣诞>金奖章>红衣主教>戴安娜。通过系统聚类将其分为3个等级:影星抗寒性较强,金奖章、红衣主教和戴安娜抗寒性较弱,其他10个品种抗寒性中等。

Abstract: Low temperature stress resistance of 14 cut rose cultivars were studied to provide references for cultivation and cold tolerance breeding in winter. The MDA content,soluble sugar content,soluble protein content,proline content,POD activity and SOD activity of annual cuttings were measured at low temperature of 5,0,-5,-10 ℃,on this basis,the membership function method was used to calculate the membership function value,and the system clustering analysis was carried out according to the value of the comprehensive membership function. The results showed that the difference of cold resistance of cut rose cultivars was obviously,the cold tolerance ability from high to low were followed by Movie Star,Tineke,Blue Moon,Rouge Meilland,Carola,John F. Kennedy,Blue Parfum,Huan zhu, Pfalzer Gold,Golden Scepter,White Christmas,Gold Medal,Kardinal and Diana. Using cluster analysis,14 cultivars were divided into three grades:low temperature tolerance of Movie star was the strongest,those of Gold Medal,Kardinal and Diana were the weakest,and the other 10 varieties were medium.

Key words: cut rose, low temperature tolerance, physiological index, membership function
