The apple tree is characterized by the different floral structures. Several researches show a relationship between the production and fruit quality and the original fruiting structure. The aim of this study was to evaluate the relationship between the floral structure and the fruit quality in the cultivars Gala, Fuji and Daiane in the mild climatic conditions in the south of Brazil. Six types of fruiting structures were characterized according to their nature and the bud size: spur of weak bud and spur of vigorous bud, short twig of terminal growth of weak bud and short twig of terminal growth of vigorous bud and long twig of terminal growth of weak spur and vigorous spur. For these different structures, were evaluated characteristics related to the phenological development, like the average dates of each phenological state and the percentage of buds that reached the different phenological phases. Patterns related to the productive potential and the fruit quality were evaluated, like the sprout and fruit set index, bud abortion index and percentage of vegetative buds, leaf area, number of flower per cluster and the length / diameter ratio of the fruits. In Gala and Fuji cultivars, the long twigs had the earlier phenological development and in Daiane...
