摘要: 本文比较了不同预冷时间和瓶插液处理对路易斯安那鸢尾‘浅紫星’切花保鲜效果。结果表明，切花在4℃冷藏3 d后，开花质量相对较好，且开花量最大。冷藏6 d后其开花质量明显下降。经75 mg/L K2HPO4 + 200 mg/L 6-BA + 50 mg/L CaCl2 + 5%蔗糖 + 75 mg/L柠檬酸处理后的保鲜效果最好，其瓶插寿命为10 d，较对照纯水的插瓶寿命延长3 d，单朵花的开花时间由2 d延长至2.5 d，开放的花朵总数增加2~3朵，每日新增开花数表现平稳。鲜切花的鲜重呈现先增加后降低的趋势，开花大小则是先减小后增加。
Abstract: In this paper, the effects of different cold storage period and fresh-keeping solution on cut flowers of Iris X Lousianna ‘Bryced Leigh’ were studied. The results showed that cut flowers after 3 d cold storage period in 4˚C was the optimal with the best quality and the maximum number of flowers. The flower quality was impaired and the flower number was declined. Meanwhile, the treatment with 75 mg/L K2HPO4 + 200 mg/L6-BA + 50 mg/L CaCl2 + 5% sucrose + 75 mg/L citric acid had the best fresh-keeping effects. Its vase life was 10 d, which is 3 d longer than that of the control (distilled water) with the flowering time of a single flower extending from 2 d to 2.5 d. The total number of blooming flowers increased by 2~3, and the daily number of new flowers was stable. The fresh weight of cut flowers was firstly increased and then decreased, while the flowering size was firstly narrowed and then enlarged.
