Abstract
The article describes new anatomical method of study of the conductive system of scion
and rootstock of grapes. A comparative assessment was given for rootstock, scion and
grape seedlings based on the values of the specific water transmissibility of xylem
tissues. The predominance of the conductive system of rootstock varieties over scion
varieties and grape seedlings was established. Zonal distribution of the cross-section
with greater functional activity of conductive vessels was shown. Dependence of values
of the specific water transmissibility of xylem tissues on such varietal characteristics of
rootstocks as strength of growth and carbon stability was established. The relationship
between the parameters of development of rootstock, scion and seedling tissues and
the specific water transmissibility of xylem tissues was determined
