Methodological aspects of conduction of researches on study of regeneration activity of grape cuttings by students of secondary schools including by members of Small Agricultural Academy of Kuban are cited in the article

There were presented the results of the researches on study of regeneration properties of grape grafts of the Saperavi variety prepared from bushes which were treated with solutions of the “Vympel” preparation and mineral fertilizers of new generation – Nutrivant Plus and Kelik potassium silicon for vegetation period three times. There was studied the influence of preparations on productivity volume from a bush and as well as main indexes of spear- and root-formation ability of grafts; there were determined the presence and degree of correlation connections between productivity from a bush and size characteristics of spears in low zone, as well as the degree of graft maturing and hormone activity of wintering buds on them on the one hand and indexes of root-formation ability of grafts on other hand

In the article there were presented the results of researches on study of influence of Moldova grape cutting treatment with Norwegian stimulator of root formation named Rudix Plus on their shoot- and root-forming ability. There were used two-,three-, four- and five-eye cuttings in the experiments

The article reviews the results of the study of the influence of lignohumates of the grade "A" («LG- АМ», «LG-А super BIO», «LG-А super L») on the grape vines treatment of the Saperavi variety on the quality must and wine in the Anapо- Taman zone of the Krasnodar region. The technology of the cultivation of grapes on the experimental plot corresponded to the adopted in the JSC "Victory" of Temryuk District, and was accepted for keeping of fruit-bearing plantations area of non-covered viticulture. Agrobiological works were carried out at the optimum time and were of high quality type. Vines of the third year of life, embodied by the scheme in 3,0 x 1,5 m. The forming was a one-sided Guyot with a height of 60 cm in trunk. There was formed the same load by shoots and clusters on the shoots. The treatment of leaf surface bushes with the solutions of lignohumates were conducted twice: 1st - before flowering and 2 nd at the beginning of the formation of berries (20 days after the first one). The spraying was carried out in the early morning hours. The accounting for the grape harvest and sampling to determine the quality of must and wine (10 kg each variant) was conducted in September 20, 2012. Technological and physical-chemical analyzes were carried out in the shop micro winemaking and accredited testing laboratory of grape processing of the SSI NCZSRIHV of RAAS. Preparations "LG-B Bio", "LG-B Super Bio" and "LG-B Super A" as grape plant growth regulators have equal and stable effect

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

In the article there were presented the results of researches of influence on study of Norwegian stimulator of root forming named Rudix Plus on regeneration properties of cuttings of Moldova and Vostorg table grapes of different lengths and as well the degrees of influence of studied factors on these indexes. The researched varieties have significant differences by a lot of important biological indexes including the potential rhizogenic activity of cuttings

The article presents the results of studies on the effect of processing varieties of grape cuttings of Pervenets Magaracha using alternating electromagnetic field on their regenerative skills. Processing the cuttings with alternating electromagnetic field was carried out using an induction coil for 5,10,15 and 20 min. As a control option, the cuttings were soaked in water, as a standard option – the cuttings were soaked for 24 hours in a 0.01% solution of IAA. Rooting was performed in vessels with water at optimum temperature conditions. It was found, that the use of IAA for the first time led to the inhibition of blooming buds. EMF treatment of cuttings with each exposure has a stimulating effect on this indicator. Application of EMF exposures in the 5 to 15 minutes resulted in a significant increase in the length of shoots, compared to the control variant and the option to IAA. Processing cuttings with EMF exposures at 5,15 and 20 minutes resulted in a significant increase in rooting compared with the control. Maximum rooting was obtained at an exposure of 15 minutes. It was the same as in the version with a standard rooting stimulant - IAA. However, the highest yield of cuttings with 3 roots and ended up in a version with a 20-minute exposure. Maximum number was noted on the heel of the roots cuttings option with IAA. Treatment of cuttings with EMF exposure 5, 10 and 20 minutes, has also led to a significant increasing of this indicator, respectively, 45.5; 22.7 and 79.5%. The maximum increase in the number of roots was obtained in the variant with exposure 20 minutes. Thus, this option should be considered as the best one

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
