In the article there were presented the results of the researches of the influence of different norms of consumption of the Nutrivant Plus water-soluble phosphorus-potassium fertilizer used for non-root additional fertilizing of Shardone grape shrubs, on accumulation of sugars in berry juice, crop productivity and quality of grape, growth processes of shrubs, quality of wine materials. The most effect is obtained at the norm of the preparation in 2 and
3kgha
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
The article presents the results of the studies on the
effect of the processing of grape variety Saperavi with
a growth regulator called Vimpel with water soluble
and foliar fertilizers of new generation - Nutrivant plus
and Kelik potassium silicon, both in pure form and in
a tank mixture. Processing of bushes was performed
three times: after flowering, growth phase of berries
(berry of a pea), the beginning of ripening berries. We
used Vimpel drug and foliar fertilizers such as
Nutrivant plus and Kelik potassium-silicon, both in
pure form and in conjunction with Vimpel; it led to a
significant increase in weight of the bunch, bush crop
and planting yields. The smallest yield increase was
provided by Vimpel. However, the combined use of
this drug on a background of Kelik silicon- potassium
foliar fertilizer and Nutrivant plus led to a greater
increase in yield from the bush than when used
fertilizers only. Processing of bushes by Vimpel in
combination with a foliar application of Kelik
potassium-silicon not only led to a significant increase
in crop yields from the bush and plantations, but in
two cases of the three it contributed to a significant
increase of the mass concentration of sugars in the
juice of berries. Using Vimpel, together with Nutrivant
plus foliar application for two years out of three
promoted maximize yields (23.4 and 18.4%) with a
decrease in sugar content, and in one year - an increase
in the harvest of 10.4%, with a significant increase in
mass sugar concentration (1.92 g / 100 cm3 or 9.2%).
Thus, the processing of Saperavi grapes with a growth
regulator called Vimpel and water soluble foliar
fertilizers of new generation - Nutrivant plus and
Kelik potassium and silicon is an effective method of
increasing the yield and quality of Saperavi grapes
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 the researches on study of influence of different forms of the Stimokor stimulator of growth (Stimikor, Stimokor sweet and Stimokor Plus) as in a pure type as in a tank mixture with Nutrivant Plus water-soluble
phosphorus-potassium fertilizer on agrobiological and technological indexes of Shardone grape. The most effect was obtained at the treatment of shrubs with Stimokor Sweet
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 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
Hereby we present the results of the research devoted
to study of influence of growth modulator called
melaphen on the technical brand of gapes such as
Sovinion White and its agro-biological characteristics.
The research was conducted in 2014-2015 using
fruitful grape Sovinion White of 2004 planting as a
subject in agro farm “Yuzhnaya” of Temruk in the
Krasnodar Region. Melaphen is a type of melamine
salt of bioximethilphosphin acid. It evokes complex
influence on the energetic complex of vegetation cell
in all three stages of vegetation. The chemical was
applied mechanically by a tractor sprinkling. The
square of tested patch is 2 hectares. Melaphen usage
was 6,7 ml to 1 hectare . Norm of liquid applied was
700 liters to 1 hectare. Three times the chemical was
applied during vegetation: before blossoming, grape
growth phase (grapes the size of a pea) and before the
grapes ripen. As a result it was estimated that three times chemical application of melaphen to Sovinion
White in dose 1.
10-9 in period after blossoming of
grapes and before the grapes ripen led to more
saturated accumulation of sugar in juice of the grapes
and also to faster ripening and harvesting, larger mass
of grape bunch amount of harvesting from a bush.
Besides, in the tested option growing processes are
accelerated and pigmentation agents are accumulated
faster in the leaves and embryo infestation in winter
sleeping core is boosted at larger scale. Better harvest
quality leads to better wine materials quality.
Application of melaphen provides higher economical
efficiency
There were presented the results of researches on study of influence of processing of grape grafts of resistant table variety Moldova by impulsive electromagnetic field on their shoot- and root-formation ability
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%
