Abstract
- Abstract: Chilling injury occurs in loquat (Eriobotrya japonica Lindl. cv. Luoyangqing) fruit when they are stored at temperatures lower than 5°C. In attempts to reduce this chilling injury, the effect of low temperature conditioning (LTC) was examined. Loquat fruit were conditioned at 5°C for 6 days before 0°C storage for up to 54 days. Control fruit stored at 0°C exhibited severe symptoms of lignification and tissue browning, and a decrease in percentage juice. LTC treatment significantly reduced these chilling injury symptoms, and doubled storage life. In terms of acceptability (tissue browning, internal browning (IB) index <0.4; fruit decay, <10%; flesh firmness, <6.0N; percentage juice, >60%), fruit could only be stored for 40 days at 0°C with a 3 days shelf life at 20°C, while LTC fruit could be stored for 60 days at 0°C with a similar shelf life. Similarly, LTC fruit could be stored for 40 days with a 5 days shelf life at 20°C, while fruit could be only stored for 20 days at 0°C with a 5 days shelf life. Our results confirm that LTC can effectively alleviate postharvest chilling injury of loquat fruit and may provide longer storage life with acceptable external and internal quality.
