Transformation of bioflavonoid complex of evergreen and deciduous Rhododendron generative organs' in the seasonal cycle development in Belarus

Abstract

Profiling trends in the transformation of bioflavonoid complex generative organs of evergreen and deciduous species of Rhododendron L. in the seasonal cycle of development in Belarus were installed. It is shown that the flowers of evergreen species are characterized by higher than deciduous species, the content of all fractions of bioflavonoids with a significant participation in their composition of oxygenated compounds as anthocyanins and flavonols and less recovered, such as leucanthocyanins and catechins. The leveling of differences between evergreen and deciduous species in the ratio of the major polyphenol fractions in the fruiting period, not only in the fruit, but also on the seed, because of the need to preserve the generative organs of genetically determined structures of the data pool connections, typical for Rhododendron L. genus were observed.
