✦ Synopsis

Abstract

Jonathan and Delicious apples were sprayed with the growth regulator Ethephon at concentrations of 250 and 500 parts 10^−6^. Fruits from each spray treatment were harvested sequentially in three stages, approximately 1, 2 and 3 weeks after treatment; then submitted to panels for sensory evaluation. Ethephon significantly enhanced hedonic scores for skin colour, flavour and general acceptability of Jonathan apples regardless of the harvest time, but had no significant effect on texture. The skin colour of Delicious apples was significantly improved by Ethephon application (regardless of harvest time) but there was no significant effect on flavour or general acceptability and texture was significantly impaired.
