Flower abortions occur largely depending on locations and years in apricot varieties that are selective in terms of climate requirements. In this study carried out with varieties having a wide range of chilling requirements in İzmir and Malatya, flower and leaf bud drop rates differed according to varieties and was found low in Malatya. During the flower bud and bloom period, Tokaloğlu, Precoce de Tyrinthe, and Iğdır varieties did not show anomalies in Malatya while Precoce de Tyrinthe had a low rate of abnormality in İzmir. Furthermore, it was determined that the flower bud drop rate decreased depending on the length of the chilling period. Key words: Abortion, chilling period, flower bud, Prunus armeniaca 1. Introduction Dormancy is important for fruit species in terms of productivity. This phenomenon occurs as a result of hormonal balance. In this case, the exchange of growth regulators such as auxins, cytokinins, and abscisic acid is involved (Viti et al., 2010). Dormancy is a complex process due to the interaction of genotype and environment (Muradoğlu et al., 2007). Dormancy, which is important in terms of regular bud development in deciduous fruit species, is emerging as paradormancy, endodormancy, and ecodormancy in buds. Chilling accumulation is needed to overcome endodormancy. Apricot is a sensitive species in terms of climatological events. In certain ecologies and years, vast .
