The purpose of this paper is to highlight the manner in which the annual growths influence the quantity of wood eliminated through cutting, taking into account the cultivar and the shape of the head as far as the nectarine tree is concerned. Due to the fact that the planting distances and density of the trees per hectare varies in accordance to the shape of the head it is highly important that we know the volume of work as well as the quantity of wood eliminated through cutting. The research took place at the RSFG Constanta over a period of 4 years and the studied nectarine cultivars were the following: Cora, Delta, Romamer 2 and Crimsongold; there were 4 shapes of the head and 4 planting distances: Tatura 6/2 m (833 trees/ha), Vertical cordon 4/1.5 m (1666 trees/ha), Veronese Vase 4/3 m (833 trees/ha) and Improved Vase 4/3.5 m (714 trees/ha). The study revealed the following: taking into account the shape of the head, the largest quantity of wood eliminated through cutting was recorded by the Vertical cordon in all the studied years (2008-2011); the quantity of eliminated wood is directly correlated with the Veronese Vase and the Improved Vase shapes in the sense that these two shapes are the most advantageous for the four cultivars, whereas the Vertical cordon requires extensive cutting works. The statistical analysis of the quantity of wood eliminated through cutting (t/ha) over the 4 studied years revealed the fact that the Cora, Delta, Romamer 2 and Crimsongold cultivars with the Vertical cordon shape of the head ensured a positive significance, while the other shapes ensured a negative significance from a statistical point of view.
