Effect of spraying with NAA and Vapor Gard on quality characters of local fruit pomegrante (Punica granatum L.).

Abstract

The experiment was conducted in a local pomegranate trees / Najaf on 1/ 7/ 2006 on 10-years old to investigate the effect of two concentrations of Naphthalene Acetic Acid (NAA) (25 and 50) mg / L and Vapor- Gard wax (2 and 4) % and combination treatment between them on quality characters of fruit.The Results indicated that, NAA gave a significant increase in the moisture peels, pulp, juice percentage and reducing the cracking, T.s.s, acidity, anthocyanine and vitamin C in juice during fruit ripening . Vapor Gard was more effective than NAA in that respect but the combination of NAA and Vapor- Gard were more compared with effective single treatments. The treatment (NAA 50mg / L + V-G 4 %) gave the best result than others.
