Rezumat

Physico-chemical analysis carried out on berries vine distant hybrids (V.vinifera L. x M.rotundifolia Michx.) of the IV generation showed that the concentration of phenolic substances, resveratrol, pectin, etc. is relatively higher in the berries with blue-violet shade. However, forest vine (V.sylvestris Gmel.), with blue-violet shade berries, has concentrations of phenolic substances, resveratrol, pectin etc. much more than distant hybrids of vine (V.vinifera L. x M.rotundifolia Michx.) of the IV generation. berries tinged with blue-violet

Analizele fi zico-chimice ale bacelor hibrizilor distanţi de viţă de vie (V. vinifera x M. rotundifolia Michx.) de generaţia a IV-a, au demonstrat că concentraţia substanţelor fenolice, resveratrol, pectina etc. este relativ mai mare bacele de nuanţă albastru-violet. Însă, viţa de vie de pădure (V. sylvestris Gmel.) cu bace de nuanţă albastru-violet, deţine substanţe fenolice, resveratrol, pectine etc. în cantităţi mai mari ca hibrizii distanţi de viţă de vie (V. vinifera L. x M. rotundifolia Michx.) de generaţia a IV-a cu bace de culoare albastru-violet.
