MODERN TECHNOLOGIES FOR GRAPE STORING
05.20.01 Technologies and means of mechanization of agriculture (technical sciences)
Description
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

Description
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

Description
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

Description
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

Description
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

05.20.01 Technologies and means of mechanization of agriculture (technical sciences)
Description
The urgent task facing the agro-industrial complex is the improvement of storage methods for agricultural products and the development of new ones. One of the actively cultivated crops, characterized by a variety of species, valuable taste and medicinal properties – grape. It is possible to provide the population with fresh grapes of high quality through the introduction of effective storage technologies that reduce losses, preserve marketable properties and biological value. One of the effective ways to preserve the quality of grapes during storage is the use of sulfur dioxide (SO2). This gas inhibits oxidative enzymes in berries, thereby reducing the rate of development of the phytopathogen Botrýtis cinérea, which causes gray rot. At the same time, it is especially important to control the rate of release of sulfur dioxide, since at the beginning of storage it is necessary to ensure the receipt of a large amount of it, which will eliminate Botrytis spores present on the surface of the berries and stabilize the existing damage. Further, during the entire period of storage of grapes, sulfur dioxide must be supplied in minimal quantities. Such dynamics of SO2 emission can be ensured by the use of two-phase generators of sulfur dioxide. The article investigated the effects of sulfur dioxide generators on the quality of grapes during storage. The study also investigates quality indicators of grapes of several varieties zoned in the Krasnodar region under long-term storage

Description
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
