The present study was carried out during the three successive seasons of 2003, 2004 and 2005 (the first season was a preliminary experimental season lo select the best concentration of each material under study)on Desert Red peach fruits to evaluate the effect of Calcium chloride (CaCI2), Gibberellic acid (GAs), Potassium permanganate (KMnO4) and Camphor oil as pre-harvest treatments on fruit quality, storage ability under 30 days of co'd storage at 2C ± and during marketing, for 2 days at room temperature after cold storage. The data revealed that, spraying peach trees two weeks before harvest with Camphor oil at 0.1% was very safety, effective for reducing decayed fruits and total loss in fruit weight at cold storage and during marketing under room temperature. In addition to keeping fruit quality ,progress fruit firmness and anthocyanin content. Moreover, GaOl2 at 1 % + KMnO4at 0.1 % enhanced fruit firmness, the content of anthocyanin and reduced loss in fruit weight. Furthermore, applied GA.3 at 25 ppm kept fruit firmness to a long time white, GA3 at 25 ppm + KMnO4 at 0.1% increased SSO I acid ratio in fruit juice which guide to expand marketing period of peach fruit in emporiums.
