Cold Tolerance of Roses in Winter on the Viaducts in Zhengzhou
Viaduct greening is an indispensable part of urban greening projects,which has important ecological and social benefits for greening and beautifying viaducts.Ten rose varieties with good performance in the open field are used as experimental materials,and their morphological observation and physiological and biochemical indexes such as soluble sugar content,soluble protein content,MDA content,SOD activity and POD activity are measured in the environment simulation experiment area of viaduct.The cold tolerance of the rose varieties is evaluated and determined with the subordinate function method.The results indicate that the rose varieties ranks from strong to weak as'Angela'>'Handimeigui'>'Rainbow's End'>'Margo Koster'>'Hongcongrong'>'Sweet Dream'>'Basino'>'Sonnenkind'>'Xialingying'>'Carefree Wonder'.Referenced with the observation of the open field,'Angela''Margo Koster''Handimeigui'and'Rainbow's End'can be applied for viaduct greening in Zhengzhou.
