BIOCHEMICAL FEATURES OF THE DISTANT HYBRIDS IN F4 (V. VINIFERA L. X M. ROTUNDIFOLIA MICHX.) AND OF CULTIVARS OF V. VINIFERA L.

E. Alexandrov

Abstract


The process of obtaining distant hybrids, as well as any crossing of cultivars of Vitis vinifera L. with representatives of species possessing the necessary qualities (resistance to diseases and pests, low temperature, etc.) may change the spectrum of chemical and biochemical compounds responsible for flavour, colour and taste of grapes, obtained juice and wine. Botanical description of distant hybrids was performed during all phases of the vegetative stages; the organs of the plants were studied from spring, at bud unfolding, until early autumn, at the fall of the leaves. For the determination of diglucoside-3,5-malvidin, the fluorimetric method, for determining the methyl anthranilate, the gas chromatographic method was applied. According to the physical and biochemical indices of the grapes of the studied distant hybrids, their characteristics are similar to European vine species.
