Abstract
Ethephon applied as a preharvest spray to Shamouti oranges at colour-break reduced fruit damage by oleocellosis. The best concentration was found to be 480 ppm when the spray was given 14–20 days before picking. Raising the pH of the spray solution to 7.0 did not lessen leaf drop nor improve the results of the original pH 2.6. The colour change at this concentration was highly correlated with the reduction of oleocellosis (–0.95), but the fruit still needed further ethylene degreening for about half the usual time. After 72 h postharvest degreening the treated fruit had a colour much closer to that reached naturally later in the season.This publication has 1 reference indexed in Scilit:
