目的 为了延长月季切花“卡罗拉”的贮藏期，选取合适的采收期进行贮藏至关重要。方法 分别以提前4 d采收(1级)、提前2~3 d采收(2级)、提前1 d采收(3级)、当天采收(4级)的月季切花“卡罗拉”为试材，于4 ℃下贮藏20 d，定期观察贮藏及瓶插期间鲜切花品质的变化。结果 与其他采收期月季切花相比，2级月季切花乙烯生成速率偏低，贮藏15 d前，2级月季切花在一定程度上呼吸强度较低，丙二醛含量整体呈现较低趋势。在贮藏20 d瓶插8 d时，2级月季切花花朵直径偏大，可维持花朵较高的开放程度，花朵萎蔫指数、腐烂指数、质量损失率仅为40.66%、82.22%、11%，均低于其他采收期的月季切花;色差中L^*值较高，b^*值较低，表明2级月季切花颜色较为鲜亮，有效延缓了黄化现象。结论 经过1 d物流运输及20 d左右的贮藏条件下存放时，提前2~3 d采收(2级)的月季切花可维持较好的品质及观赏价值。

To prolong the storage period of cut flowers "Carola", it is important to select the appropriate harvesting period for storage. The cut flowers of "Carola" were harvested 4 d ahead of time (grade 1), 2-3 d ahead of time (grade 2), 1 d ahead of time (grade 3), and on the same day (grade 4), and then stored at 4 ℃ for 20 d. Changes in the quality of the cut flowers were regularly observed during storage and vase insertion. The ethylene production rate of grade 2 cut flowers was lower than that of other harvested cut flowers, and the respiratory intensity of grade 2 cut flowers was lower than that of other harvested cut flowers to a certain extent before 15 d of storage, and the malondialdehyde content of grade 2 cut flowers was lower than that of other harvested cut flowers. At 20 d of storage and 8 d of vase insertion, the flower diameter of grade 2 cut flowers was large, which could maintain a higher degree of flower opening. The wilting index, decay rate and weight loss rate of the flowers were only 40.66%, 82.22% and 11%, which were lower than those of other cut flowers at the harvesting period, and the colour difference of the flowers had a higher value of L, a lower value of b, which indicated that the colour of grade 2 cut flowers was brighter and the yellowing phenomenon was effectively delayed. In conclusion, if the flowers were stored under 1 d of transport and 20 d of storage, the quality and ornamental value of the cut flowers could be maintained if the flowers were harvested 2-3 d earlier.
