Abstract:
The particularities of the functional activity of the leaves of grape plants (Vitis vinifera L.) depending on the lighting conditions were carried out. It is shown, that the grape plants during phylogeny, growing in forest communities, characterized by high adaptability to different lighting conditions. In low light leaves is intensified biosynthesis of plastid pigments, especially included in the light-harvesting complex that promotes the capture of photons scattered light and intensity of the photosynthetic apparatus.
