The article presents the research results of eight grapes rhizogenesis of different genetic origin of the cuttings after treatment with 0.01% solution of IAA for 24 h. It was found, that the activity of regenerative processes in grape cuttings depends on the varietal characteristics, storage conditions and the activation of IAA. It leads to disruption of existing natural correlations, including suppressing the longitudinal polarity. Root-growing ability of cuttings is a genetically determined feature: the effect of IAA did not cause the stability of the positive reaction; it is determined by genotype and depends on the quality and physiological condition of the cuttings
Researches on non-root additional fertilizing of grapes with complex water-soluble fertilizer called Nutrivant plus have been conducted in corporation "Pobeda" in Temrjuksky area of Krasnodar territory on the implanted plantings of technical grade Rhine Riesling. In the test, the following kinds of Nutrivant plus were used: oleiferous (N0P20K33), sugar beet (N0P36K24), grapes (N0P40K25), universal (N19P19K19), grain (N6P23K35). Each mark of Nutrivant plus contained a certain set of microelements. The test consisted of six variants:1 variant - without additional fertilizing(control); 2 variant: grapes - before flowering, grapes - a growth phase of berries (a berry about a pea), oleiferous - the beginning of maturing of berries; 3 variant: universal - before flowering, universal - a growth phase of berries (a berry about a pea), oleiferous- the beginning of maturing of berries; 4 variant: grain - before flowering, grain - a growth phase of berries (a berry about a pea), oleiferous- the beginning of maturing of berries; 5 variant: Sugar beet - before flowering, a sugar beet - a growth phase of berries (a berry about a pea), a sugar beet - the beginning of maturing of berries; 6 variant: universal - before flowering, grain - a growth phase of berries (a berry about a pea), grapes - the beginning of maturing of berries. Norm of the expense of fertilizer is 3 kg/hectares. The expense of a working liquid - 700 l/hectares. The result was, that in the third, fourth and fifth variant of the test the increase in a crop from a bush happened accordingly on 7,5, 13,8 and 17,8 %. The maximum increase of a crop in the fifth variant was accompanied by increase in mass concentration of sugars in juice of berries on 0,6 g/100 см3и decrease titratable acidities for 0,6/dm3 As a result triple not root additional fertilizing of grapes plants grade Riesling with Nutrivant plus (universal - before flowering, grain - in a growth phase of berries and grape - in the beginning of maturing of berries) promoted more optimization of a water mode of leaves, increase in weight of a cluster, a crop from a bush and productivity, mass concentration of sugars and phenolic substances in juice of berries
The article presents the results of three-year researches of root-formating ability of grafts of 9 resistant table and technical grape varieties of native and foreign selection at their rooting in water.
Among studied indexes of root-formaing ability of grafts, the best varieties were Moldova, Lyana, Riton and Pervenets of Magarach
The article reviews the results of the study of the influence of treatment of Saperavi grapes with the growth regulators (Biodux and Avibif) on the quality of grape must and wine in the Anapо-Taman zone of the Krasnodar region
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 research results on regeneration activity of
wilding cuttings of phylloxeraresistant varieties of
grapes influenced by heteroauxin treatment are
analysed in the article. The preliminary studies were
held in All-Russian research institute of viticulture
and wine-making of Ya.I. Potapenko using cuttings of
3 grape varieties – Berlandieri x Riparia Cober 5bb,
Riparia x Rupestris 101-14 and Berlandieri x Riparia
CO-4. The cuttings were soaked during 48 hours in
0,005 % heteroauxin and were implanted in sand in
adjustable conditions of temperature, humidity and
aeration. In 2012-2013 experiments were continued in
Kuban State Agrarian University. The varieties
Gravesak, RSB and Berlandieri x Riparia Teleki 5C
were added to the experiment. Three-items buds were
shooted in damp steamed sawdust in a film hothouse.
In preliminary researches application of heteroauxin
has allowed to increase root-growing by 20,3-40,0 %.
The greatest increase of root-growing (40 %) was
observed on variety СО-4, that is characterized by the
weakest potential rhizogenesis activity, and the least
(20,3 %) on control variety Cober 5 bb. Next
researches show that treatment of cuttings basal ends
by 0,01 % heteroauxin activated their regeneration
process, that was expressed in: increase in sprouts
length – variety 5 C, 101-14 and Gravesak by 23,1-
157,6 %; increasing of cuttings root-growing from
16,7 % on variety 5C to 60,0 % on variety Cober 5 bb,
the quantity of cuttings with not fewer of 3 roots from
accordingly 13,0 % to 54,7 %; increasing of roots
from 0,7 on variety СО-4 to 2,7 on variety 101-14 or
in 1,7-2,7 times. The application of heteroauxin on
variety RSB did not show positive results, because of
the variety peculiarities
The article reviews the results of studying the influence
of mineral fertilizers on the qualitative indices of the
Merlot grape variety in the Anapo-Taman zone of the
Krasnodar region. The technology of cultivation of
grapes on the experimental plot was in accordance with
the accepted for the given zone and culture.
Agrobiological work was carried out at the optimal
time and had a high quality of execution. Grape bushes
are laid in a 3.0 x 2.0 m pattern. Formation - a twoshoulder
horizontal cordon. On the bushes we formed
the same load of shoots and bunches. Scheme of the
experiment: option 1 – no fertilizers (control); option
2-superphosphate with a mixture of potassium salt
(P90K90) from the autumn; option 3 –nitroammofoska
(N120P120K120) from autumn; option 4 – ammonium
nitrate (N60) in early spring. Analysis of the results of
studies on the study of biological features of growth,
fruiting, yield and quality of Merlot grape varieties on the background of the use of mineral fertilizers shows
their high efficiency in the conditions of the AnapoTamanskaya
zone of the Krasnodar region and can be
recommended for use in production conditions.
Mineral fertilizers ensures the receipt of dry bulk wine
of superior quality control sample (without fertilizers)
the concentration of tartaric acid 17.3 25.1 percent,
phenolic compounds 17.1 – 40.0 %, and alcohol
content of 7.2 and 9.3 %, titratable acids 11.8 and 13.7
%, given extract by 17.4 %, with a decrease of the
mass concentration of total sulfur dioxide and pH. The
most effective is the introduction of NPK
(N120P120K120)
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
The article presents the data on the formation of the embryonic fruitfulness of central ovaries of wintering buds of the group of technical grape varieties with white berries - White Muscat; Pinot White, Chardonnay, Citron Magaracha, Pervenets Magaracha; Riesling, Viorica, Riton, Crystal in the conditions of Anapa-Taman zone. There were revealed the rates of embryonic fruitfulness of central ovaries of buds of studied cultivars and fruiting indices of vegetative shoots developed from them. In all studied grape varieties there was revealed a high percentage of fruitful buds from 84,1 in the variety of Riton at 97.2 at Viorica; and the percentage of fertile vegetative shoots from 81,8 at the variety Citron Magaracha to 97.2 in the variety White Muscat. At the leveled load of bushes, vegetative shoots and the same scheme of planting of bushes (3 x 2 m), the highest yield in terms per hectare showed the varieties Pervenets Magaracha, Viorica, Riton, Crystal, Riesling and Citron Magarach. When assessing the economic efficiency the highest net income and level of profitability were identified in the varieties of Citron Magaracha, Pervenets Magaracha, Viorica and Riton. In order to determine which buds will give us shoots with large, well-developed (well-differentiated) buds, and which will not give (weakly differentiated), it is necessary "to look inside a bud". But even already formed germs of inflorescences in the bud are able in a few days in spring or dedifferentiate or degrade depending on the influence of external conditions. Scientists have learned to use this ability to increase the maximum possible yield in years of severe damage of grape by frosts. Firstly, in frosty winters the central buds wither out. The replacing buds usually have poor fruiting and bad productivity during years. In such cases, it is more profitable to conduct a small cutting of angle buds arranged in a circle at the base of a shoot. At the beginning of the second vegetation phase, these buds will obtain the great bulk plastic substances, which will cause the dedifferentiation of rudiments of inflorescences in them. Thus, it is possible not only to restore rapidly the normal shape of a bush, but to obtain a good harvest this year
