Culture system of trees fruit production efficiency in relation to light as an output influencing factor

Abstract

The training systems in orchards depending on the desired objectives. Along with the parameters of biological, ecological and technological resources that govern the productivity, the orchard, to the extent possible to satisfy more envisaged objectives. Without doubt the scientific value of these objectives will mention their decisive character in the choice of culture. Several objectives have been proposed recently with such an approach. We present here a bibliographical review of some of the elements which constitute the ground of their conception such as potential of biological production, optical system, light utilisation, plant density, and latitude of the locality.
