Performances of low chill cherries under subtropical conditions
Cherry harvesting time in the world is mostly concentrated in June and July, as it is the same in Turkey. Out of season cherry growing in April, May and August is getting more important in Europe as well as in California, USA. For this purpose, an orchard was planted in 2010 with the planting distances of 3×1 m in Adana at Abdioglu village (17 m altitude). The cherry cultivars used in the experiment were: Minnie Royal, Royal Helen, Royal Lynn, Royal Hazel, Rosie, Royal Nuie (Bailey), Royal Edie, Royal Tioga, Royal Marie, Minnie Royal and Royal Lee. The chilling requirements of these cultivars were: Minnie Royal (400-500), Royal Helen (750), Royal Lynn (500), Royal Hazel (500), Rosie (R. Rainier) (700), Royal Bailey (Ansel) (750), Royal Edie (750), Royal Tioga (500), Royal Marie (Royal Tenaya) (500), and Royal Lee (500). The chilling accumulation in hours below 7°C during 2016 and 2017 winter period was calculated to be 652 h in Adana and 540 h in Abdioglu village. The blooming and the harvesting dates of some cherry cultivars were: Royal Tioga: bloomed on March 8 and harvested on April 20, Royal Lynn and Royal Marie: bloomed on March 8 and harvested on April 27.
