Physiology and Control of Superficial Scald of Apples: A Review

Abstract

Superficial scald (storage, common scald) is an extensively studied postharvest physiological disorder of apples. Research on superficial scald of apples before 1965 was reviewed by Hardenburg (26); that reported since is summarized in this paper.

Transcription factor MdLSD1 negatively regulates α‐farnesene biosynthesis in apple‐fruit skin tissue

“…Superficial scald is a common physiological disorder of apples during the late stage of low-temperature storage (Ingle et al 1989). Studies have shown that cytosine methylation-based epigenetic regulation is involved in scald resistance (Karagiannis et al 2018), and a crucial role of polyphenol oxidase (PPO) and especially of the glutathione S-transferase (GST) protein in scald progress has been suggested (Karagiannis et al 2020).…”

Effect of Storage Conditions on the Volatilome, Biochemical Composition and Quality of Golden Delicious and Red Delicious Apple (Malus domestica) Varieties

“…The impact of storage conditions on the abundance of (E,E)-α-farnesene is important, as although (E,E)-α-farnesene with its green, oily and fatty notes contributes mainly to the vegetable descriptor of apple fruit [85], the products of (E,E)-α-farnesene oxidation could induce scald disorder [86][87][88]. The superficial scald of fruit is induced with prolonged storage at low temperature, and its severity is related to the storage temperature [89].…”
