The article presents the results of the studies on the effect of processing grape cuttings of different lengths with Norwegian rooting stimulator called Radix plus on their regenerative capacity. In the experiment we used two-, three-, four- and five buds cuttings of Vostorg table grape variety, characterized by weak rooting activity. Paraffined and pre-processed by growth regulator, these cuttings were rooted in vessels with water. The studies found that with the increasing length of cuttings we decrease the degree of blooming buds, which is associated with the manifestation of the longitudinal polarity. Processing cuttings with Radix Plus leads to inhibition of blooming buds and shoot growth, which is enhanced by increasing the length of cuttings from two to five buds. The maximum of rooting ability of the cuttings and output with 3 or more was reached by roots of two-buds cuttings. The regularity of these parameters decrease with increasing length of the four buds cuttings with some increase in the five buds; the maximum number of roots was reached by two buds and five buds cuttings. Using of Radix Plus reduces the difference between the rooting on short and long cuttings. The most consistent effect of Radix Plus is the output of the cuttings with 3 roots and more on three buds cuttings, and on the increasing number of roots - in the three- and four buds cuttings. When germinating the cuttings of Vostorg variety in comfortable conditions, without using
growth regulators, it is better to use two buds cuttings, and in the case of pre-processing them with Radix Plus – we suggest three buds cuttings
