There were determined the close correlation dependence between the energy of propagation of wheat seeds sunk in water in which the grape cuttings were rooted on one side and the rooting and output of cuttings with three roots and more on other side by the authors. There were the equations of regression for prognosis of rooting and output of cuttings with three roots and more

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

The article presents the results of the studies of the processing effect of the growth regulator called Stimolante 66f (Stimolant) on cuttings of Moldova grape variety as well as on the regenerative properties, yield and quality of seedlings. We have tested three concentrations of the preparation - 0.001; 0.01 and 0.1% as compared with heteroauxin treatment (standard), and no treatment (control). The experiments have been conducted in the laboratory and in the field. In the lab experiment cuttings were rooted in the vessels with water, and in the field they were planted in open ground. Processing cuttings with heteroauxin led to a delay in blooming of the buds of 0.4 days, and with Stimolante - to acceleration of the process to 0.3-0.8 days. Processing cuttings with heteroauxin and with Stimolante at 0.01 and 0.1% had an inhibitory effect on the growth of shoots, which survived until the end of the experience. Using Stimolante at 0.01 and 0.1% resulted in a stimulation of rooting cuttings and increased the output by 3 or more roots. Heteroauxin stimulated rooting only in the initial period. More roots formed on cuttings processed by heteroauxin and Stimolante at the minimum concentration of the drug, i.e. 0.001%. In the open ground, the best results for the yield and the quality of the seedlings were obtained with concentration of 0.1% of Stimolante. Heteroauxin showed worse results than Stimolante in optimum concentrations like in the rooting of cuttings on the water as in the open ground

The article is dedicated to the features of the correlations between the indicators of shoot and root growth ability of grape cuttings varieties of Moldova and Vostorg of different lengths, under the influence of the processing them with Norwegian growth regulator - Radix plus. We have found that in the control variants on both varieties there are fairly close correlation connections between the number of shoots, their length and the degree of blooming buds. However, in the advanced options the character of the relationship between these parameters depends on the varietal characteristics manifested in the potential root activity cuttings. For Moldova cuttings which are characterized by high root activity, the use of Radix plus led to some strengthening of the correlations, and for Vostorg (with the weak activity of rooting of cuttings) - to decreasing of the correlations. This fact may indicate that the negative effects of growth regulators on the activity of endogenous hormones in the cuttings of Vostorg varieties, which explains the decrease of rooting of longer cuttings. Processing the cuttings of Moldova with Radix plus led to increasing in the frequency and extension of the correlations between shoot and root growth ability of cuttings. For Vostorg, on the contrary, the use of Radix plus led to the weakening of these connections. The reason for this phenomenon, as is the case with figures of shoot growth ability may be a change in the activity of the endogenous phytohormone influenced by exogenous auxin. Character of correlations identified between indicators of root growth ability of cuttings shows that rooting depends primarily on the hormonal activity of cuttings, number of roots - on cuttings plastic substances, and the yield of cuttings with 3 roots and more - on both of these points

This article is devoted to treatment effects of cuttings of a grape variety called Moldova with 0.01% solution of heteroauxin on their regenerative capacity, depending on the light conditions. We have established that the germination of cuttings in the dark, as well as the treatment of heteroauxin significantly stimulate their regenerative abilities. The length of the shoots, regardless of the use of heteroauxin, depends on the mode of the light produced during the germination of cuttings. In both studies, the length of the shoots on the end of experiment cuttings germinated in the dark, was 1,71-2,66 times more than when germinated in the light. Cuttings rooting ability also largely depends on the light produced in their germination. In both studies, the rooting of cuttings started earlier and passed more rapidly during their germination in the dark. Processing cuttings with heteroauxin, followed by germination in the dark, speeded up the formation of roots even more, compared with the case where the cuttings treated with heteroauxin germinated in the light. In the best case rooting increased by 42,5-47,5%, the number of roots on basal ends of cuttings in 18,3- 18,5 times, the numbers of cuttings with 3 or more roots to 72,5-80,0%
