Abstract

The present study was conducted in 2007/2008 and 2008/2009 seasons in order to extend harvest season and maintain fruit quality for better marketability of Washington navel oranges  growing in clay soil by preharvest  foliar sprays (at color break stage) with GA3, 2,4-D, putrescine and calcium either alone or in combinations. Trees were harvested at mid- February (late in the season). All sprayed substances delayed fruit softening, peel ageing and fruit color break and decreased creasing and preharvest fruit drop. Also, fruit TSS, sugars and V.C. contents were increased. The treatments had positive influence on extending harvest season without any deterioration in fruit characteristics. In general, spraying the different substances in combinations gave better results, especially for putrescine and 2,4-D.
