Biochemical Changes of two Cultivars of Golab and Shafiabadi Apple at Harvesting Time and After Storing

Aim and Background. Physiological characteristics of two apple cultivars (Golab and Shafiabadi) were surveyed after harvesting and storing at the Agricultural Pardis and Natural Resources of Tehran University. Materials and Methods. Two cultivars were selected and some certain physiological characteristics were examined twice. These characters were weight, volume, density, extracted volume, PH, amount of solved and unsolved material, dry matter and ethylene hormone of the fruit. Results. The result showed that there were significant differences among characters between two examined cultivars and also the differences were significant between two times of sampling among fruit weight, PH and ethylene amounts.Conclusion. There were significant differences between two apple cultivars corresponding to ethylene amount, Golab cultivar produces much more amount of ethylene compared with Shafiabadi cultivar.
