摘要: The development of a model the vertical and horizontal distribution leaf, shoot, fruit surface area densities, SAD (surface per unit canopy volume, m 2 · -3 ), as well leaf types (main lateral leaves) ages is described for two systems (Espalier-type, S-System, 3-wire Cordon, C-System). Leaf, shoot increased towards interior both reached maximum values 12, 0.8, 1.2 , respectively, 10, 0.4, 1.0 m C-System. zone was always located near areas highest density. surfaces leaves different from primary secondary shoots distinctly tested.
