Abstract:

Purpose of the review: Salicylic acid (SA) is an important component in the signal transduction pathway and is also involved in local and systemic resistance to pathogens. Exogenous application of SA at nontoxic concentrations could enhance the resistance of fruits to pathogens.

Main findings: In this review, we mainly introduce the controlling effect of exogenous SA treatment on postharvest diseases in different fruits and discuss the physiological response of fruits to SA treatment. These results are important for fully understanding the function of SA in the defence response of fruits to pathogen infection.

Directions for future research: Future studies should focus on the mechanisms of action of SA in systemic resistance of fruits using molecular, proteomic and metabolic approaches, and identify the molecular events involved in the signalling of SA-induced disease resistance in fruits.
