Ethylene Production by Chilled Cucumbers (Cucumis sativus L.) 1

Abstract

Chilling at 2.5 C accelerated the synthesis of 1-aminocyclopropane-1-carboxylic acid (ACC) and C2H4 production in cucumber fruit. Skin tissue contained higher levels of ACC and was more sensitive to chilling than was cortex tissue. Accumulation of ACC in chilled tissue was detected after 1 day of chilling and remained elevated even after C2H4 production started to decline. These data suggest that ACC synthesis is readily stimulated by chilling, whereas the system that converts ACC to C2H4 is vulnerable to chilling injury. Chilling-induced C2H4 production was inhibited by amino-ethoxyvinylglycine, sodium benzoate, propyl gallate, 2,4-dinitrophenol, carbonyl cyanide m-chlorophenylhydrazone, and cycloheximide. The utilization of methionine for ACC formation and chilling-induced C2H4 biosynthesis was established using l-[3,4-14C]methionine. Chilled tissue had a higher capacity to convert l-[3,4-14C]methionine to ACC and C2H4 than did nonchilled tissue.
