The aim of this experiment was an examination of the plant hormone physiology of preharvest fruit cracking in pomegranate (Punica grantum L.). The experiment was carried out with the cultivars 'Izmir 10', 'Izmir 15', 'Izmir 16', 'Izmir 23', 'Izmir 26', 'Silifke Asisi' and 'Hicaz', 4 replicates of each, at the research and experimental field of the Agricultural Faculty of Cukurova University, Turkey, in 2001 and 2002. Abscisic acid (ABA), indole 3- acetic acid (IAA) and gibberellic acid (GA(3)) contents were measured in the fruit peel of all the cultivars. At the same time, the yield and percent fruit cracking for all cultivars have been determined. The highest fruit cracking rates were in Izmir 10 and Silifke asisi, the lowest was in Izmir 16 in 2001, while the highest was in Izmir 15 and the lowest was in Izmir 16 in 2002. The ABA content of the peel was generally higher in cracked fruit than in the peel of healthy (non-cracked) fruit.
