Abstract
The apple tree is characterized by the different flowering structures.
The fruit production is related to the quality of the flowers, and several researches indicate that the characteristics of the flowering structure are fundamental in the flower development and, in consequence, the fruit as well.
The objective of this study was to evaluate the possible influence of the flowering structure in the flower production and the fruit set in three apple cultivars: Gala, Fuji and Daiane. The highest sprout index in Gala and Fuji were found in the long twigs, and the lowest results in the spurs.
In Daiane only the spur of weak buds showed a lower sprout index than the other structures.
Regarding the fruit set, the best results were obtained in the long twigs of vigorous buds, and the worse results in the spurs for all the three cultivars.
