Özet

Temperature (high and low) is one of the most limiting environmental factors for growth and production of fruits in different parts of the world. For temperate-zone fruit species, a certain total heat requirements are needed in order to obtain ripe fruits. The aim of this study was to determine heat requirements of three commercial pomegranate cultivars ('Suruc', 'Katirbasi' and 'Hicaznar') grown in Southern Anatolia region. The cultivars showed a narrower range of heat requirements for flowering (growing degree hours, GDH), i.e. 'Suruc' (25,000), 'Katirbasi' (25,270), 'Hicaznar' (28,000) and a wide range of heat requirements for fruit ripening, i.e. 'Suruc' (73,670), 'Katirbasi' (74,105) and 'Hicaznar' (88,052) GDH. Under the Sanliurfa province conditions, two years average of effective heat summation requirement from bud swelling to 50 % flowering stage for 'Suruc', 'Katirbasi' and 'Hicaznar' cultivars are calculated as 643, 655 and 718 growing degree days (GDD) and from bud swelling to harvest are 2734, 2802 and 3289 GDD. It can be concluded that the effective heat summation of Sanliurfa province is enough for commercial growing for all pomegranate cultivars.
