摘要
以6个微型月季品种带叶枝条为实验材料,置于-10、0、5、20℃温度条件下处理24h,测定不同品种叶片相对电导率、含水量、脯氨酸含量、丙二醛含量和可溶性糖含量等不同生理指标,并结合露地生长形态观察综合判断植物耐寒性的强弱。综合比较结果表明,‘白珂斯特’抗性较强,‘紫微星’、‘金太阳’、‘冬梅’次之,‘小女孩’和‘矮仙女’较差,可为上海乃至长三角地区筛选耐寒性强、观赏性高的优质微型月季品种和合理栽培提供参考。
Branches with leaves of six miniature rose cultivars were treated under -10,0,5 and 20℃ for 24 h to evaluate their cold resistance. Several important physiological indexes of different cultivars,including relative conductivity and the content of water, proline, MDA and soluble suga were measured, which combined with morphological observation in the open field indicate that the ability of cold resistance of ＇White Koster＇ is the strongest, then ＇ Purple star＇, ＇Gold Sun＇, ＇ Winter plum＇, ＇Litter girl＇, and ＇Dwarf beauty＇. The reuslts provide a reference for the selection of high quality miniature rose cultivars with strong cold resistance and high ornamental performance and its rational cultivation in Shanghai, even in Yangtse River Delta Area.
