Determination of flower bud drop and anomalies under different ecological conditions of some apricot cultivars

Abstract

Efficiency in fruit trees is connected with flower quantity and quality. Flower abortions occur largely depending on locationsand years in apricot varieties that are selective in terms of climate requirements. In this study carried out with varieties having a widerange of chilling requirements in İzmir and Malatya, flower and leaf bud drop rates differed according to varieties and was found lowin Malatya. During the flower bud and bloom period, Tokaloğlu, Precoce de Tyrinthe, and Iğdır varieties did not show anomalies inMalatya while Precoce de Tyrinthe had a low rate of abnormality in İzmir. Furthermore, it was determined that the flower bud drop ratedecreased depending on the length of the chilling period.
