In this study, we investigated the impact of rainfall rate and temperature during fruit development on chilling injury (CI) ofQueen pineapples ( Ananas comosus L. Merr) after cold storage at 13 °C. The pineapples were induced to fl ower in October2016 and May 2017. Rainfall and fi eld temperature during fruit development were recorded. The fruit were harvestedin March 2017 and October 2017 (135 d after anthesis), respectively. Visual appearance, CI score, lightness ( L *) value,parameters related to membrane integrity, and the activities of enzymes related to browning of the tissue adjacent to thecore were monitored in the fruit after 7 and 14 d of cold storage followed by room temperature storage (27 ± 1 °C) (RT) for2 d. High CI incidence was associated with high rainfall rather than the fi eld temperature (approx. 27–29 °C) during fruitdevelopment. The fruit harvested in March experienced higher rainfall during fruit development than the fruit harvested inOctober. The CI severity of the fruit harvested in March was greater than that of fruit harvested in October. The higher CIseverity of the fruit harvested in March was accompanied with reduced membrane integrity as well as enzymatic browningcompared to the fruit harvested in October. In conclusion, high rainfall during fruit development is a major factor for CI ofQueen pineapple grown in tropical zones. The results of this investigation provide insight into the causes underlying the lossof fruit quality during storage and marketing.
