STUDY OF THE INFLUENCE OF TREATMENT WITH SULFUR ANHYDRIDE ON GRAIN QUALITY INDICATORS IN THE STORAGE PROCESS

abstract 1602006015 issue 160 pp. 194 – 208 30.06.2020 ru 144
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

YIELD PREDICTION OF TECHNICAL GRADES OF GRAPES WITH THE WHITE COLOR OF BERRIES ON THE BASIS OF A STUDY OF THE EMBRYONIC FRUITFULNESS OF BUD IN THE CONDITIONS OF ANAPA - TAMAN AREA OF THE KRASNODAR REGION

abstract 1211607094 issue 121 pp. 1545 – 1582 30.09.2016 ru 436
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
