The determination of growth situation of some apricot cultivars in Aydin region

In this research, to determine earliness and vegetative growth performances of four apricot cultivars in Aydın ecological conditions was aimed. The research was out in newly planted fruit collection parcels in Adnan Menderes Univercity in 2012 and 2013 years. Beside the phenological obsarvations and evaluate of morfological data, in Zaza cultivar chilling units was made. In both years, phenological obsarvations in cultivars showed the differences. When morphological data were evaluated, Iğdır (Aprikoz) and Roxana gave the positive results for the both years. In Zaza cultivar, chilling units for 2012 and 2013 were found as 697 and 685 CU respectively. The earliest flowering occured in Zaza cultivar. The Roxana cultivar which had the highest chilling unit requrements showed the latest budbreak. In the light, obtained data adaptation to the region off all cultivars used in this were found promising for future.
