Evaluation of dormancy break in some selected peach (Prunus persica) cultivars

Abstract

The evaluation of dormancy break based on the number of flower buds in bloom was performed in years 2011-2013 (January-April) for 15 peach cultivars compared to the control cv. Redhaven. Based on the date of endogenous dormancy break the evaluated peach cultivars could be classified into three groups consisting of: (1) cultivars with an early break of dormancy, (2) cultivars with a medium-early break of dormancy and (3) cultivars with a late break of dormancy. For individual cultivars, the duration of the dormancy period was influenced by meteorological conditions existing in a given year.
