The paper reviews the results of the study in in Anapо-Taman zone Krasnodar territory e of influence treatment vines Saperavi growth promoters Immunotsitofit, Krezatcina and HB-101ECO on quality parameters wine
The article presents the material of forecasting for grape
yield of next year and establishing the optimal loading if
cutting of bushes. The material includes 14 varieties of
grapes, 11 of them are technical and 3 are table ones. For
each year of stable high yield of grapes, it is necessary to
pre-set the optimum length of fruit cutting of shoots and
optimum load on the bush healthy eyes. To do this for
each variety on the eve of trimming bushes we perform
optimum productivity analysis of wintering buds of fruit
along the length of shoots, i.e. we implement forecasting
of grape yield for next year. We have a plan of forecasting
for yields of vineyards by microscopy of wintering
buds on one-year shoots of fruit ripened grapes in order
to establish the potential of embryonic establishment of
inflorescences in the central holes of buds. Based on the
analysis of buds, the indices were calculated for wintering
fruiting buds and their degree of damage during the
growing season. It was revealed, that the majority of
grape varieties under study shows high tab embryonic
inflorescences in central buds in overwintering buds for
next year yield. Higher rates at a rate of fruiting buds
were wintering in the varieties: Moldova (section 27). -
1.66; Bianca (section 6). - 1.83; Kunlean (section 15). -
1.71; Merlot (section 14). - 1.64; Saperavi (section 56). -
1.76. The lowest rates of fructification - the varieties
Muscat Hamburg (section 21) and Augustine (section
11) and were respectively 1.20 and 1.24. As a planned
productivity, we offered the optimal loading model of
cutting bushes buds. As a result of productivity analyzes
of buds along the length of the fruit shoots in 2016 we
recommended to carry out pruning of fruit annual shoots
3-4 buds of the form of AZOS-1 and the form of cordon
- 5-6 buds
In this study we have shown the influence of fruitless shoots to number of berries in clusters, the mass of 100 berries, average weight of the bunch, yield, sugar content and acid in the juice of the berries, the quality of wine. These indicators have been studied at a ratio of fertile and sterile shoots 1: 1, 3: 1, 6: 1 with a load of bushes 12, 16, 20 fruit-bearing shoots and nutrition area 3 x 1 m2. Control was a natural balance of fruit-bearing and barren shoots. Digital material is processed by one-way analysis of variance experience for each load of bushes, and then the same method of two-experience for all the options. Fragmentation of sterile shoots with load of 12 fruit-bearing shoots per plant decreases, and with loads of 16 and 20 increases the number of fruit-bearing shoots berries in clusters, the mass of 100 berries, average weight of the bunch, yield, and sugar content in berries. For the content of titratable acids we have marked a tendency to increase with a decrease in the number of sterile shoots. The content of phenolic substances on the variants of the experiment was 2.2-2.3 g / dm3, the acidity of 7.3-7.8 g / dm3, alcohol 10,2-10,9% vol. Dry wines tasting score on the options was in the range of 7.4-7.6 points. Significant difference in taste and smell features wines by variants of the experiment was not revealed. Conclusions on the effect of sterile shoots on fruiting vine indicators drawn from the analysis of variance one- and two-factor experiments, in most cases were the same
The article presents the results of studying the influence of some types of packaging materials used in conjunction with Inter Fresh’s ethylene absorber (sachets) on commercial quality and losses of Alexandria zucchini, Lyubov sweet pepper and tomatoes cv. Inkas during storage. The study was carried out using StePac Xtend bags, creating a modified atmosphere. The objects of research were stored for 14 days at a temperature of 8 – 10 °С and air relative humidity of 90±3 %. One sachet for ethylene absorption was placed in Xtend bags. It was found that when stored under these conditions, the total weight loss is: for tomatoes – 0.3% when using Xtend bags and Inter Fresh ethylene absorbers, 1.8% when using traditional packaging materials; for zucchini – 0.4% when using Xtend bags and Inter Fresh ethylene absorbers, 1.6% when using traditional packaging materials. Losses associated with microbiological damage during storage of zucchini and tomatoes were not observed. During storage of sweet pepper microbiological spoilage took place, which, apparently, was the result of increased contamination with pathogenic microorganisms
Fruits are an important part of the diet of humans and
many animals. In case of an improperly organized
process of storing of fruits, the loss of mass and
decrease of quality can be substantial. This makes
relevant the research, aimed at enhancing existing and
developing new technologies of fruits storing. In this
article, the results of the investigation of influence of
complex treatment of fruits with electromagnetic fields
of extremely low frequency (EMF ELF) and а biopreparation
on the change of microbial contamination
of their surface and on the loss of mass in the process
of long-term storage are revealed. Apples of the Idared
variety and pears of the Conference variety were the
objects of research. The change of microbial
contamination of the surface of fruits, undergone a few
types of pre-treatment (EMP ELF, bio-preparation
“Vitaplan”, complex treatment “EMP ELF + the biopreparation”
and no special treatment), after storing during 7 months in case of pears and 8 months in case
of apples is shown in the article. It was found, that the
greatest decrease of content of microorganisms on the
fruits’ surface is achieved as a result of the complex
treatment, combining the treatment with EMP ELF and
an aqueous solution of the “Vitaplan” bio-preparation.
The effective parameters of such a treatment for apples
and pears are represented
Technologies of fruits storing known at the present
time, solving actual problems – slowing down
biochemical processes, inhibiting ethylene synthesis,
do not provide fully the preservation of quality of
fruits due to not taking into consideration the
peculiarities of microflora of fruits and
microbiological processes, taking place during storage.
Purpose of the research: investigation of influence of
complex treatment of fruits with electromagnetic fields
of extremely low frequency (ELF EMF) and the biopreparation
“Vitaplan” on changing of losses of
biologically active substances in the process of longterm
storage. Objects of the research: apples of the
Idared variety and pears of the Conference variety,
regionalized in the Krasnodar region. Mass shares of
the vitamin C and P-active substances were measured in the process of storing. ELF EMF treatment was
conducted on an experimental installation. Fruits were
exposed to the action of electromagnetic fields with
specified parameters. Complex treatment of fruits
(apples and pears) with ELF EMF and the biopreparation
“Vitaplan” before dispatching for storage
allows preserving the biologically active substances –
the vitamin C and P-active substances – to the
maximum degree. Synergetic effect, appearing due to
the complex action of electromagnetic field and the
bio-preparation, allows decreasing the processing time
in the electromagnetic field
The article gives a review of modern technologies of storage of grapes. The main tool for stabilizing the quality of grapes during transportation and storage is the use of sulfur dioxide (SO2), a gas that has properties that can inhibit non-enzymatic darkening, reduce the activity of enzymes, effectively control the development of Botrytis cinérea (a phytopathogen that causes gray rot) and acts as an antioxidant. Researchers pay particular attention to control the release rate of SO2, as it is important in the first stage storage to ensure supply of significant quantities of SO2 for a short period of time, which eliminates Botrytis spores that are present on the surface of berries and to stabilize the damages formed during transport and filling; the second step is to ensure a steady supply of the minimum quantity of the SO2, to ensure the control of microbiological spoilage. For a long storage time. To preserve the quality indicators of grapes during storage, it is possible to use a modified gas environment created in various ways, including through special types of packaging; forced saturation of the environment with gases such as oxygen, ozone or carbon dioxide. At the same time, to enhance the effect can additionally apply fungicides, antifungal ear Anti-mold®, etc. There are known technologies for complex processing of table grapes to combat post-harvest microbiological spoilage, which provide for the first stage of treatment with ozone or sulfur dioxide followed by spray treatment with Muscodor albus. An alternative to the use of SO2 is the use of essential oils and hypobaric treatment methods that ensure minimal environmental impact. Positive results during storage are provided by the use of medium-range ultraviolet radiation (UV-B) or short-wave radiation (UV-C), which positively affect the transcription of biosynthetic genes, providing an increase in the content of phenolic compounds and antioxidant activity of grapes, without affecting the content of dry soluble substances, the value of total titrated acidity and pH during storage. The analysis of modern technologies is of interest to practitioners and researchers who develop technologies for storing grapes

The article presents the results of a study of the influence of the processing method before storage on the commercial quality of carrot roots during storage. The object of the research was carrot of the Abaco variety. Objects of study were stored for 21 days at + (25 ± 1) ° C and 56 days at + (2 ± 1) ° C. Roots were treated with extremely low frequency electromagnetic fields (EMF ELF) and Vitaplan biopreparation separately and in combination. As a result of the research, it was established that the complex treatment of EMF ELF and biopreparation allows increasing the yield of standard carrot products compared to the control: 11.8% at storage temperature + (2 ± 1) ° C, 24.1% at storage temperature + (25 ± 1) ° C. A reduction in the total losses of carrots, treated with complex EMF ELF and biological product, was found by 5.8% at storage temperature + (2 ± 1) ° C and by 12.4% at storage temperature + (25 ± 1) ° C
