Physiology of plum fruit ripening

Purpose of review: Plum fruit exhibit varying types of ripening behaviour that is highly dependent on genotype, harvest maturity, and pre- or postharvest handling practices. This article focuses on recent advances in the physiology of plum fruit ripening.

Findings: Recent studies have reported that in plums: (1) harvest maturity is associated with the ability of fruit to ripen properly, which ultimately affects consumer acceptance; (2) harvest maturity, storage temperature and storage period affect the level of sugars and organic acids; (3) malonyl 1-amino-cyclopropane-1-carboxylic acid and malonyl transferase activities are the main regulatory factors controlling fruit ripening and some other possible ethylene-related disorders during cold storage; (4) development of chilling injury symptoms after cold storage are associated with ethylene biosynthesis and abnormalities of cell wall metabolism including reduction in pectin solubilisation and depolymerisation and decrease of galactose-rich pectin as well as postharvest oxidative stress; (5) great variations exist in the concentrations of bioactive compounds and antioxidant activities depending on various pre- and postharvest factors.

Directions for future research: Highly perishable nature, delicate skin, chilling sensitivity, and other postharvest physiological disorders, and the consistent supply of high quality fresh and safe fruit to the consumer are great challenges to postharvest physiologists. Development of non-destructive maturity assessment, quality evaluation methods for plum fruit warrants investigation. Molecular and conventional breeding approaches to regulating plum fruit ripening and improving their shelf-life have not resulted in substantial success. Determining whether ethylene is directly involved in promoting pigment accumulation or is triggered by another effector needs further investigation. Various factors that may affect the development of postharvest oxidative stress such as fruit ripening and storage disorders in plums (including genotype, harvest maturity, storage temperature, storage period and atmosphere composition) warrant further investigation.
