Effect of low temperature storage on fruit physiology and carbohydrate accumulation in tomato ripening-inhibited mutants

Abstract

Chilling-sensitive fruits often produce a burst of ethylene when reconditioned at ambient temperature after cold storage. This has led some researchers to propose that chilling injury (CI) may be induced by post-chilling ethylene production. To test this hypothesis, we examined two tomato (Solanum lycopersicon L.) mutants, non-ripening (nor) and ripening-inhibitor (rin), that do not produce climacteric ethylene, after they were subjected to cold-storage and reconditioning. The response of the mutants differed, and was not as extreme as the parent line cv. Ailsa Craig, but both showed symptoms of chilling stress. Therefore while ethylene production may influence chilling injury, it is not essential for initiating this process in tomato cv. Ailsa Craig.

Mechanical Models of Compression and Impact on Fresh Fruits

“…Therefore, mechanical actions do have a large influence on physiological changes in the postharvest handling of fruits. In order to improve the textural quality of fresh fruits in markets, postharvest handling processes are performed at low temperatures that delay fruit ripening (Ahmad and others ; Luengwilai and Beckles ). Some packaging such as foam net sleeves and plastic trays are used to relieve compression and impact events (FAO ; Scetar and others ).…”
