In the low temperature storage of fruit with high maturity at harvest, no serious chilling symptoms were
found in the fruits stored for 7, 14 and 21 days. After the
low–temperature–stored fruits were exposed at 21 °C
for three days, their overall quality was also good: the
peel and flesh showed desirable appearance, suggesting
the ripening process of fruit was completed. At the day
28 of storage at 1 °C, the fruit harvested with high maturity
showed good appearance; however, serious chilling
symptoms appeared in the flesh after the three days
ripening treatment at 21 °C. The major symptoms of the
chilling injury were internal browning and inability of
flesh softening (Table 2), followed by small dark brown
spots found on the skin. Because of the difficulty to control
full softening, the hardness of flesh varied among
fruit individuals with high standard deviations (Table 2).
