摘要： 选取6个芍药品种, 分别为春晓、山河红、奇花争露、紫凤朝阳、菱花晨浴、蓝海碧波为材料, 研究其体内生理生化变化与瓶插寿命的关系。结果表明:瓶插过程中, 游离脯氨酸含量呈先下降后上升趋势, 可溶性蛋白质、可溶性糖、Mg含量呈先上升后下降趋势, K含量在瓶插过程中变化趋势分为两种类型:先上升后下降型与持续下降型。芍药切花的瓶插寿命与Mg含量的变化呈极显著正相关, 与可溶性蛋白质的变化呈正相关, 与游离脯氨酸含量呈负相关, 与K、可溶性糖含量的变化相关性较低。

Abstract: The relationship of physiological and biochemical characteristics with the vase life of cut peony flowers was studied. Six cuhivars, including Chunxiao, Shanhe Red, Qihua Zhenglu, Zifeng Chaoyang, Linghua Chenyu and Lanhai Bibo were investigated. The results showed that during the vase-holding, free proline content declined first and then increased;soluble sugar content, soluble protein content and Mg content increased first and then declined. K content of some cultivars increased first and then declined, the others declined. Mg content had with the vase life, soluble protein content had with it. Free praline content had with it. K content and soluble sugar had little correlation with it.

Key words: Cut peony flower, Vase life, Physiological and biochemical characteristics
