摘　　要：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1d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.
