Fruit harvests were performed at intervals of 15-20 days. The dry weight and oil content of Fuerte cultivar increased by 110.2% and 234.2%, respectively, between October and May of the 2010-2011 harvesting period. The dry weight and oil content of the Bacon cultivar increased by 44.7% and 180.7%, respectively, between October and March of the 2010-2011 harvesting period, and increased by 51.0% and 174.1%, respectively, between October and January of the 2012-2013 harvesting period. The dry weight and oil content of the Zutano cultivar increased by 47.4% and 200.0%, respectively, between October and March of the 2010-2011 harvesting period, and increased by 25.9% and 86.3%, respectively, between October and February of the 2012-2013 harvesting period. A very strong positive correlation between certain pomological properties used as fruit maturity indices in avocados were found in the Fuerte, Bacon and Zutano cultivars. As a result of this study; with regard to the dry weight and oil content of fruit grown in the climatic conditions of Antalya, the optimal harvesting periods were determined to be between November and May for the Fuerte cultivar, and between November and January for the Bacon and Zutano cultivars.
