Grapes on the quality divided
by the elite, first and second grades, as well as sub-standard.
Elite plants must have at
least four of the roots, the thickness of the base - at least 2 mm, the
roots should be relatively evenly positioned around the circumference at
the base of trunk, length of matured growth - at least 25 cm and the
thickness of the base - at least 5 mm.
Seedlings first grade should
have normal growth of one or more shoots. It is necessary to have at
least one of them matured for at least 20 cm from the base. At the base
of trunk should be at least four roots, relatively evenly spaced around
the circumference, and two of them must be a minimum thickness of 2 mm
at the base of trunks.
By second grade seedlings
include those that increase the quality and development of root systems
do not meet the requirements of plants first grade. At the same time
they must have at least three nodes matured growth and at least two
normally developed roots at the base of trunks.
Seedlings with unripe or
slightly ripe growth are substandard and should be rejected as defective
