Effects of 2-alkyl-2-cyclopropene-1-carboxylic acid ethyl ester on ethylene production and flesh softening of non-astringent persimmon fruit

The effects of 2-alkyl derivatives of 2-cyclopropene-1-carboxylic acid ethyl ester (CPE) with various lengths of alkyl side chains were examined on ethylene production and flesh softening of ‘Taishuu’ and ‘Fuyu’ persimmon (Diospyros kaki L.) fruit. When the ‘Taishuu’ fruit were treated with gaseous forms of the CPEs with short alkyl chains, the increased ethylene production and decreased flesh firmness of fruit were not inhibited. However,...
