- Аннотация: The changes in chlorophyll, carotenoid and quercetin glycoside content were studied in two apple (Malus domestica Borkh.) varieties, Braeburn and Granny Smith, with different ability for acclimation to sunlight, during their on-tree ripening under full-spectrum solar radiation and without UV component. Exclusion of solar UV did not affect the development of the variety-specific patterns of photosynthetic pigments during fruit ripening and adaptation to the visible solar radiation. On the contrary, solar UV was crucial for the accumulation of quercetin glycosides, the main group of phenolics serving for UV acclimation in apple fruits. High content of quercetin glycosides (QG) was maintained in the sunlit skin of fruits grown with solar UV in the course of ripening. Apart from solar UV-inducible QG in sunlit skin, there was a ' background ', level of these compounds in the shaded skin that was not affected,by solar UV. The QG of shaded apple skin presumably originate from constitutive phenolic metabolism and may serve for protection against diffuse UV of sunlight scattered by canopy.
