Physiology of pre-harvest fruit cracking in pomegranate: mineral contents

The aim of this experiment was an examination of the effect of fruit peel mineral contents on physiology of pre-harvest fruit cracking in pomegranate (Punica grantum L.). The experiment was carried out with the cultivars ‘İzmir 10’, ‘İzmir 15’, ‘İzmir 16’, ‘İzmir 23’, ‘İzmir 26’, ‘Silifke Aşısı’ and ‘Hicaz’, at the research and experimental field of the Agricultural Faculty of Çukurova University in 2001 and 2002. Mineral contents of fruit peel belonging to these cultivars have been examined in cracked and uncracked fruits.
At the same time, the yield and fruit cracking percentage of all cultivars have been determined.
The highest fruit cracking percentage rates were found in ‘İzmir 10’ and ‘Silifke Aşısı’, the lowest was in ‘İzmir 16’ in 2001, while the highest was in ‘İzmir 15’ and the lowest was in ‘İzmir 16’ in 2002. It was determined that the cracked fruit peel contained lower levels of potassium, potassium:calcium ratio and potassium: (calcium + magnesium) ratio; and on the contrary, higher levels of nitrogen, calcium, and nitrogen:potassium ratio.
