Abstract
The article presents a study of the influence of various rootstocks on the change in the quality of cuttings of Chardonnay grape variety in the conditions of the Central zone of the Krasnodar region. In the course of the research, the following calculations and observations were carried out: the average diameter of the shoot and core, the cross-sectional area of the shoot, core and wood, as well as the aging coefficient and the conditional aging coefficient were determined. Compliance with the quality standards of cuttings of the Chardonnay variety, depending on the rootstock, was determined using the aging coefficient in accordance with GOST 28181-89, as well as using the conditional aging coefficient according to the method of Prof. N.V. Matuzok. Scion-rootstock combinations with the best indicators of maturation in the conditions of the central zone of the Krasnodar region were identified.
