Potted Ficus ginseng was used to study the effects of different postharvest temperature on the changes of defoliation and stress-resistant physiology during storage and transportation. The results demonstrated that the best postharvest temperature could significantly reduce membrane permeability and malondialdehyde (MDA) content of leaves, postpone the degradation course of penetrative adjustive substance in leaf and the descent of chlorophyll content and poly-phenols aegis enzyme activity of leaves, improve anti-stress capability during storage and transportation, delay Ficus ginseng decrepitude, and reduce the defoliation rate (16% defoliation rate after 36 days’ storage and transportation at 10±1 ℃ and 13±1 ℃ ). Moreover, lowering the temperature gradually, 2 ℃ each day, to storage and transportation’s temperature before storage and transportation at 10 ℃ could reduce defoliation rate after 36 days’ storage and transportation.
