We have compared changes in α-farnesene and conjugated trienols, as well as gene expression, in scald-resistant cultivars, e.g., ‘Gala’ and ‘Braeburn’, and in scald-sensitive cultivars, e.g., ‘Granny Smith’, ‘Delicious’ and ‘Law Rome’. We also carried out similar comparisons in ‘Granny Smith’ between controls and treatments that diminish scald symptoms, e.g., low O2 and 1-methylcyclopropene (1-MCP). The data show that the initiation of the C2H4 climacteric plays a crucial role in scald development, since treatments that retard the onset of the climacteric, e.g., low O2 and 1-MCP, also inhibit symptoms of scald development. Furthermore, if either low O2 or 1-MCP is applied after the initiation of the C2H4 climacteric, their inhibitory effects on scald development decrease. The treatments that retard the C2H4 climacteric onset also strongly inhibit the rise in
