Plant polyamines are involved in many growth and developmental processes. Polyamine concentrations change during fruit development and ripening. Cold storage has been reported to be effective for preserving the quality of fruits, although internal breakdown, surface pitting, peel discoloration and abnormal ripening (chilling injury symptoms) are sometimes observed. Changes in polyamine concentrations are related with the development of chilling injury, but whether increased putrescine concentrations are a protective mechanism or the cause of the stress-induced injury remains unclear. Mechanical stress is other stress that fruits experience when exposed to compression, impact and vibration during handling and packaging lines. The role of polyamines during some physiological processes affecting fruit ripening and postharvest life, and polyamine behaviour (both infused and endogenous) in fruits submitted to chilling injury and mechanical stresses are discussed.
