Proper fruit coloration is very important topic in all apple growing regions, because it can be influenced bymany technological measures applied (hail net, training system, etc.). Therefore it is a subject of continual research in connection with the influence of light reduction under hail nets or exposure of fruit to different light intensities. The objective of our studywas toupgrade these results in a complex experiment with precise studies which also involve fruit metabolites. We tried to determine the changes in fruit lighting for different positions in the tree canopy under and outside the hail net,and the influence of position in the tree canopy and consequently differences in lighting on the content of phenolic compounds(phenolic acids and different groups of flavonoids), fruit coloration and content of pigments, such as individual cyanidin 3 glycosides,chlorophyll and carotenoids in apple skin, cv. ‘Fuji’.
