When the apple trees are cultivated in mild winter regions like in Southern Brazilian conditions show a long growth period, with shoot growth above of 1 meter. Actually the apple orchards have been established in high density systems, with spacing of 4.0-4.5 m between rows and 0.8-1.2 m between trees, in the central leader system and modified forms. In the spring shoots restart the growth, however the shoots tend to budbreak in middle third apical, and the others buds do not show growth, mainly near the stem insertion point. Shoot growth measures in orchards of first and second year show a shoot growth of 128.2 cm and 142.5 cm, respectively for ?Gala? and ?Fuji? cultivars. These shoots show a strong apical dominance and may show a growth cessation during the vegetative season with growth reassumed in the season end. When the vegetative growth is reassumed there is the formation of small area with very weak buds, which also occurs in the growth resumption in apical buds in the next season. The high density needs to reduce shoot size, but without the apical dominance increase. In order to determine the effect of pruning at the growth cessation point, experiments were done to evaluate the time and intensity of pruning to keep a canopy with short shoots. The results show that it is possible to keep short shoots compatible with the high density spacing, reducing bending and stimulating the formation of fructification structures along the shoots. Pruning should be done during the growing season and may be complemented with the growth retardants. The ratio of 2/3 of the shoot diameter in the stem insertion point develops shoots very strong for the high density system, being more appropriate ratio of 1/3 to 1/5 of the shoot diameter for the primary and secondary shoots.
