This study presents results on the response of apricot cultivars (Aleksandar, Biljana, Vera, Roksana) to the cutting back of one-year-old shoots during summer pruning conducted at different dates: 15 June (T1), 1 July (T2) and 15 July (T3). A positive response to one-year-old shoot pruning involved feather shoot development during the same growing season. The following parameters were evaluated: percentage of positive responses, feather shoot number and major morphological traits of feather shoots (length, flower bud number and vegetative bud number). The results obtained suggested the highest positive response in T1, followed by T2 and T3. All cultivars responded to shoot pruning, with Roksana showing the most positive response in terms of feather shoot development in about 90% of cases. As for the morphological traits, T1 induced excessive vigour in feather shoots as opposed to those in T3 which exhibited low vitality and poor relationship between generative and vegetative buds. The best results (moderate vigour and good relationship between generative and vegetative buds) were obtained in T2.
