Abstract

The color and shape of ‘Delicious’ apples were improved with a combination treatment of (2-chlorethyl)phosphonic acid + α-(2,4,5-trichlorophenoxy)propionic acid (ethephon/fenoprop) and gibberellin A4A7 plus N-(phenylmethyl) 1H-purin-6-amine (GA4,7/BA). All ethephon/fenoprop treatments improved red color development. The length/diameter (L/D) ratio of fruit treated with GA4,7/BA, GA4,7/BA plus ethephon/2,4,5-TP, and GA4,7/BA plus ethephon/2,4,5-TP plus daminozide was greater than untreated fruit. The L/D ratio of fruit treated with GA4,7/BA plus daminozide did not differ from those not treated. The length, diameter, and weight of fruit treated with daminozide alone was less than for untreated fruit. Diameter of fruit treated with GA4,7/BA + daminozide or daminozide + GA4,7/BA + ethephon/fenoprop was less than for untreated fruit.
