Changing the light regime during the growing season by using photoselective nets in devices protecting against hail can have an impact on the yield and its quality. The white and black nets used do not change the spectral composition of the light passing through the grids, but act as shades, reducing the amount of light that passes through the grids. The influence of this effect on the sensory characteristics of Pinova apple fruits was investigated in an orchard with a support structure with an anti-hail net located in Northern Bulgaria. The sensory evaluation of the Pinova cultivar shows that the fruits under the most commonly used black net in orchards do not differ significantly in taste, aroma, and consistency from those grown under white, yellow, and red coverings. Only the influence of different types of nets on the appearance of the fruits of the Pinova apple cultivar has been statistically proven.
