Inhibitory effect of 1-MCP on ripening and superficial scald development in 'McIntosh' and 'Delicious' apples.

McIntosh and Delicious apples were treated with the competitive ethylene (C2H4) antagonist 1-methylcyclopropene (1-MCP), to evaluate its feasibility as a postharvest tool for use by the apple industry. The threshold concentration of 1-MCP required to inhibit de novo C2H4 production and action was 1 micro l l-1. 1-MCP treatment completely inhibited C2H4 production in apples for 6-10 d at 20 deg C following storage at 0 deg C in air or controlled atmosphere for 60 or 120 d. 1-MCP-treated apples were significantly firmer (13 to 20 N) than untreated apples following storage and post-storage handling for 7-14 d at 20 deg C. Total soluble solids of apples was not affected by 1-MCP treatment. Inhibition of total volatiles and alpha -farnesene emanated by apples by 1-MCP treatment was parallel to the inhibition of C2H4 production by 1-MCP. Contents of alpha -farnesene and its putative superficial scald causing catabolite, conjugated triene alcohol, in the skin were reduced 60-98% by more than or equal t

o 1 micro l l-1 1-MCP. Treatment with 1-MCP suppressed the incidence of superficial scald in McIntosh and Delicious apples by 30% and 90%, respectively.
