Influence of trellis system and soil type on grapevine vegetative growthThis work evaluates the influence of two trellis-training systems (lyre and vertical), and two soil types (sandy and clay) on grapevine vegetative growth. The observed differences were greater on axillary shoot growth than on main shoots, and they are linked to the precocity determined by soil type. The effects of summer pruning and hydric stress associated to trellis-training systems were responsible for differences on growth speed of shoots and axillary shoots.
