Abstract

We studied changes in the intensity of ethylene release and accumulation of 1-aminocyclopropane-1-carboxylic acid during ripening of two apple varieties characterized by various physiological states and treated with halothane derivatives and L-alpha-(2-aminoethoxyvinyl)-glycine. We observed changes in activity of the protein polygalacturonase inhibitor in the fruit tissue and accumulation of oligouronides. The data suggest that pretreatment with the inhibitor of 1-aminocyclopropane-1-carboxylic acid synthase affects ethylene release, accumulation of 1-aminocyclopropane-1-carboxylic acid, activity of the protein polygalacturonase inhibitor, and potential intensity of oligouronide formation in apple fruits and tissues.
