Abstract Curcuma hybrida ‘Red Torch’ belonged to Zingiberaceae, which can be used as a garden green flower and fresh cut flower. At present, there are few studies on the postharvest growth of ‘Red Torch’. To explore the appropriate harvest treatment methods, in this study, according to the growth of scape during the full flowering stage of ‘Red Torch’, it was divided into five periods for harvesting, and inserted into the deionized water; The same growth period of ‘Red Torch’ was separated from water 0, 2, 4, 6 h and then resealed in bottle to observe its performance. The result shows that, the cut flower performance was closely related to the development of scape at the time of collection, and the vase performance of cut flower was optimal at the middle stage of development after collection; the cut flower ‘Red Torch’, rehydrating immediately after harvesting in field, performance in bottle work best, even it's bottle life lasted for 26 d. ‘Red Torch’ cut flower's life will be reduced significantly with water deficit over 4 h (P<0.05). Therefore, ‘Red Torch’ should be harvested in the middle stage of scape development, and rehydrate as soon as possible after harvesting, which can achieve better preservation effect and higher quality.
