摘要: Kiwifruits are often exposed to various temperature fluctuations (TFs) during postharvest transportation and storage. To evaluate the effect of TFs on the qualities of kiwifruits during storage, kiwifruits were stored at 2 degrees C, 2 degrees C or 5 degrees C (TF2 degrees C-5 degrees C, alternating every 12 h), 2 degrees C or 7 degrees C (TF2 degrees C-7 degrees C, alternating every 12 h) for 3 d before long time storage at 2 degrees C. Observations revealed that kiwifruits stored at a constant 2 degrees C showed the lowest loss of weight and vitamin C because of minimized ethylene production and respiratory rate compared with that of TF2 degrees C-5 degrees C and TF2 degrees C-7 degrees C. Moreover, the results of RT-qPCR verified that the expression levels of genes encoding polygalacturonase, beta-galacturonidase, and pectin methylesterase were significantly increased by the treatment of TF. Hence, TF accelerated the degradation of cell walls, softening, translucency, and relative conductivity of the flesh of kiwifruits. In addition, the impact of TF2 degrees C-7 degrees C on kiwifruits was more significant relative to TF2 degrees C-5 degrees C. The present study provides a theoretical basis for kiwifruit during cold storage.
