Abstract
The experiment was carried out on the ‘Devil Gala’, an interesting clone belonging to the ‘Gala’ group.
This cultivar, especially when fruit thinning is insufficient, produces fruit that do not reach the expected size.
In addition, if fruit size is unsatisfactory, the fruits of the cultivar belonging to ‘Gala’ group cannot be maintained on the trees to try to increase fruit size and other quality characteristics and appearance because the fruit can undergo cracking near the peduncle that can compromise fruit’s integrity and its shelf-life.
The aim of the experiment was to test the effectiveness of the well-known thinning agent MaxCel (6-benzil-adenine) largely used on apple and to determine the efficacy of the combination with s-ABA (abscisic acid) formulation.
S-ABA was also evaluated alone to detect its efficacy as a thinning agent and in combination with MaxCel to verify the possibility to further increase fruit size as well as to positively affect other fruit quality characteristics.
