Abstract | The article presents the results of research as to the influence of contour pruning on the illumination of parts of the crown of apple cvs. Wilmuta (Jonagold), Gala and Golden Delicious on M.9 rootstock (with manual correction of the space between trees). The illumination of trees is growing with the height increase; however the greatest value is detected at the top of the crown. The index is considerably larger in the case of contour pruning in the phase of a pink bud and the greatest influence on its change is caused by the action of the term of pruning | ||
