The cold-tolerance of ‘Kristal’ (Euro-Amur-American
origin), ‘Dostoyniy’ and ‘Krasnostop AZOS’ (interspecific hybrids of
Euro-American origin) grapevine varieties in the conditions of the Russian South
winter is characterized by the second (true dormancy) and third (induced
dormancy) winter-resistance components. Here, a complex approach is used to
estimate the plants adaptability to abiotic stress factors. We used gravimetric
method for humidity assessment and water content; spectral analysis for
detection of the protein level and pigments; capillary electrophoresis method to
analyze the level of carbohydrates, Krebs cycle organic acids, phenolcarbonic,
ascorbic acids, and amino acids. The obtained results allow to suppose the
various mechanisms of adaptation of the studied varieties to the winter period
stressors. The water content of the shoots, the level of protein, aminoacids,
proline, sugars and the sum of phenolcarbonic and ascorbic acids are the most
informative indicators of grape plants frost-resistance in the climate
conditions of Anapa - Taman region.
