Pomegranate (Punica granatum L.) is a drought resistant fruit species and is well adapted to Mediterranean conditions. The differences among the cultivars in respect to fruit cracking, an important physiological disorder, seems to be significant. The research work is conducted on six pomegranate varieties: two classified as sensitive to cracking, Koycegiz and Siyah, two as resistant to cracking, Kadi and Lefon and two as intermediate, Cekirdeksiz (Seedless) and Feyiz. Primary nutrients (leaf and fruit), leaf gas exchange properties, leaf water potential and fruit characteristics were investigated and correlated with the ratio and tendency of cracking.
