Abstract:

The effects of different harvest stages on postharvest quality of mango fruits (Mangifera indica L. ‘Hongmang No.6’) during storage at ambient temperature were studied to provide theoretical basis for rational harvesting of mango fruit. The changes of weight loss, decay index, flesh firmness, vitamin C (Vc), total soluble solids (TSS), titratable acid (TA) and TSS/TA of mango fruits were determined. The results showed that in mango fruits harvested too early, the TA and Vc levels were higher, and TSS and TSS/TA were lower than those harvested timely. However, in mango fruits harvested too lately, the weight loss and decay index were higher, and softening was faster than those harvested timely. These results suggested that the optimal harvest stage of ‘Hongmang No.6’ mango fruits was 120 days after full bloom and the suitable harvested physiological index were that the mass fraction of TSS and TA were 6.40% and 0.85% respectively.
