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

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...
