| 摘 要： | 以6个芍药品种‘春晓’、‘山河红’、‘奇花争露’、‘紫凤朝阳’、‘菱花晨浴’、‘蓝海碧波’的切花为材料，瓶插观察其外部形态特征变化，测其膜透性、MDA含量、 超氧阴离子生成速率及SOD、CAT活性的变化，研究其衰老进程、膜脂过氧化与瓶插寿命的关系。结果表明：‘春晓’、‘菱花晨浴’、‘奇花争露’能达到最大开放程度，盛开期为3 d，瓶插寿命分别为8 d、7 d和7 d；‘山河红’、‘紫凤朝阳’、‘蓝海碧波’盛开期为2 d，瓶插寿命均为6 d。瓶插过程中，膜透性、MDA含量、 超氧阴离子生成速率持续上升， SOD、CAT活性先上升后下降。膜脂过氧化造成的细胞膜损伤是启动芍药切花衰老的生理原因之一。

| Abstract: | This paper studied the senescence process and the relationship of the membrane-lipid peroxidation with the vase life of cut peony flowers. Six cultivars, including 'Chunxiao', 'Shanhehong', 'Qihua Zhenglu', 'Zifeng Chaoyang', 'Linghua Chenyu' and 'Lanhai Bibo' were investigated through observing the changes of morphologic characteristics and determining the indexes of membrane permeability, MDA content, superoxide anion accumulation rate, SOD activity, CAT activity. The results showed that 'Chunxiao', 'Qihua Zhenglu' and 'Linghua Chenyu' exhibited 3 days' full opening period and could be in full blooming with 8 or 7 days' vase life. 'Shanhehong', 'Zifeng Chaoyang' and 'Lanhai Bibo' exhibited 2 days' full opening period and 6 days' vase life. During the vase-holding, the membrane permeability, MDA contents, superoxide anion accumulation rate increased, and the increasing of them was positive to each other. The SOD and CAT activities increased at first and then declined. The damage of cell membrane because of the membrane-lipid peroxidation might be the causal factor of cut peony flowers senescence. |
