Description
The pathogenic agent of apple scab disease, Venturia inaequalis (Cooke) Winter, causes significant damage to the industrial production of apples. Studying the pathogen in pure culture is important for solving the theoretical and practical issues of its biology. The sporulation ability of the Venturia inaequalis laboratory culture is an important diagnostic feature in morphological culture analysis, in the test for sensitivity to fungicides, when creating a collection inoculum for an artificial infection. We have studied the morphological features of conidiogenesis of pure V. inaequalis culture, such as the location of conidiogenic structures and their form. For the first time in the laboratory culture of the pathogen, sporulation in the thickness of agar on the substrate mycelium was demonstrated. Conidiogenesis proceeded according to the blastic-annellidic type. Depending on the location of the conidiogenic structures on the aerial or substrate mycelium, their morphology was different. Conidiogenic areas in the substrate mycelium could be observed with the unaided eye, in the form of hyphal grit, while they were conidia conglomerations in each annelid. Annellide had a curved shape. On the aerial mycelium, annelids were straight and always had only one conidium. Differences in the morphology of conidiogenic structures are supposed to be related to the physical conditions of the environment in which sporulation takes place. In the agar, each mature conidium remaining at the apex of the annelid interferes with the formation of the next one, which results in its bending. The fixed arrangement of conidiogenic structures and forming conidia in the thickness of agar allows the use of substrate sporification for model studies of the conidiogenesis process

Description
The article considers the types of functional stability of reproduction processes in industrial fruit growing. We have substantiated the necessity of developing methodological bases for ensuring and managing the stability of reproduction processes. Methodological bases for managing the stability of reproduction processes have been developed, taking into account the specifics of industrial fruit growing as a complex organized system, consisting of biological, technogenic and economic subsystems. We have also proposed an algorithm for ensuring and managing the sustainability of reproduction processes, which is the basis for the development of digital technologies for managing the sustainability and efficiency of industrial production. The work reveals and defines factors influencing the level of sustainability and efficiency of reproductive processes, the relationship and interaction between result indicators and factor variables; it identifies emerging imbalances in the organization of reproduction processes in industrial fruit growing. Using methods of mathematical statistics, we calculated an integral indicator of the functional stability of reproductive processes and gave its semantic interpretation. It was found that the structural elements of reproduction processes are inconsistent with the actual indicators that characterize functional stability, with the normative parameters. This trend makes it necessary to develop a mechanism for managing sustainability and tools for influencing functional zones in order to bring actual indicators to the standard level. When developing tools for sustainability management, the following were clarified: management methods, process goal setting, functional load of the management object, level of organization, various restrictions (criteria) related to the specifics of technological and economic relationships and mutual influences. We have developed a mechanism for ensuring and managing the functional stability of reproduction processes in industrial fruit growing by its types, including the following stages: automated database formation; cognitive analysis of the influence of factors on the functional areas of influence by types of stability; assessment of functional stability and justification of the integral indicator; filling in, compensating for missing information, generating information data; determining the optimal parameters of functional stability; developing regulators for leveling functional imbalances in the organization of reproduction processes that ensure effective and sustainable management of industrial production

Description
This article is devoted to the definition of criteria for the functioning of agrocenoses. It is determined that the functioning of agrocenoses largely depends on the resource potential: used ecological zones, applied technologies, technological operations and regulations. The basis of effective reproduction and sustainability of agrocenoses is the optimal balance of resources used. The work purpose is the substantiation of optimal parameters of resource intensity of the technological processes in horticulture and the determination of the limits of sustainability of agrocenoses under anthropogenic influences. The integrated assessment of resource intensity of production and technological processes in industrial fruit growing for optimization of its parameters of resource intensity is given. The optimum of reproduction possibilities and limits of stability of agroecosystem components in comparability with the level of technogenic load is achieved by means of regulation of permissible anthropogenic loads in separate elements of agroecosystem and resource balance of elements and processes. The limits of sustainability of fruit agrocenosis under anthropogenic influences are substantiated as well. Regression dependences on technological processes in the context of certain types of resources used are established: capital (depreciation), turnover (material consumption and coefficient of consolidation) and labor (wage). The complex coefficient of efficiency of the economic mechanism of resource saving is defined. The article substantiates optimal parameters of resource-intensive production and technological processes in industrial horticulture. We have also calculated the normative value of the total index of resource intensity of technological processes

SYSTEM-WIDE INDICATORS AND ASSESSMENT OF STABILITY OF REPRODUCTION PROCESSES IN BRANCH PRODUCTION
Description
Methodical approaches to assessment of stability of reproduction processes which cornerstone formation of system of the balanced indicators which is based on coordination of functional and system-wide stability is are developed. The system of estimated indicators of stability is offered. The analytical model of assessment of stability providing the choice of criteria of efficiency and formation of system of estimated indicators is developed, as well as the analysis of dynamics of the external influencing factors, productive and economic indicators, financial and economic indicators; identification of the most characteristic and significant functional interrelations and dimension of interference of factors; assessment of reproduction opportunities of subjects of branch business. Calculation of an integrated indicator of financial and economic stability is performed. The complex assessment of stability providing combination of private indicators of eco-economic, technological and economic, financial and economic stability in an integrated indicator by means of methods of multidimensional correlation is given. The analysis of the factors influencing the level of stability and efficiency allowing estimating reproduction opportunities of the economic entities making grapes and wine-making production to define interrelations and interferences between resultant indicators and factorial signs and also to designate the arising disproportions is carried out. The generalizing characteristic of the macroeconomic, market and production factors influencing stability of reproduction processes in industrial wine growing is given. Based on the carried-out analysis of the factors causing stability and efficiency of reproduction processes in industrial production of grapes, the main reasons reducing stability of branch production are established

Description
The article presents a study on agro-biological and technological indicators of Don indigenous wine grapes in the conditions of the Anapa-Taman area of the viticulture of the Krasnodar region. It was found that the introduced varieties are consistent with the conditions of the area and can be recommended for growing in production plantations in southern Russia. On ripening, the varieties are as follows: the early ripening varieties are Sibirkovy; a group of middle-ripening - Aligote, Plechistik, Varyushkin; to the medium-late - Bessergenevsky 10 and Krasnostop Anapsky. Highest yield was proved to for such grape varieties as Bessergenevsky 10 (150 kg / ha) and Varyushkin (140 kg / ha). Test grapes of Aligoté and Krasnostop Anapsky showed an average yield of 120 and 130 kg / ha, respectively, red and Sibirkovy Plechistik - 140 and 135 kg / ha. Comparing the current literature with the results, we noted the following notable differences: all the studied indigenous wine grapes in the conditions of the Anapa-Taman area of the Krasnodar region matured earlier, had higher productivity indexes and gave higher yields, than in the conditions of their homeland Rostov region

Description
The features of seeding and vegetative reproduction of Hibiscus Syrian (Hibiscus syriacus L.) in the South regions of Russia are accounted in the article. It is shown that the not sorted Hibiscuses reproduce better by seeds. Sowing is made before winter (November). The young growth appears on April-May of next year. The seedlings of first-year are wintering badly in the open soil; therefore, it is better to keep them in the basements in sand. When one-year seedlings are planting next spring we receive the standard seedling in the autumn this year. Planting material of high quality of Hibiscus Syrian was grown by means of inoculation and by the grafting method. It is recommended to execute an inoculation in the first tenday period of September. It is possible to execute the reproduction by means of inoculation in case of deficit of shoots of high quality plants and for the rapid fixing of sort. It is preferable to reproduce a Hibiscus Syrian by wood shoots in the frames or by green shoots in the unheated greenhouses in an autumn-winter period. The best results in the carried out research were got at planting shoots for further growth in the containers at the greenhouses with creating of shadow in a summer period. The high speed of shoots growth in the containers of cv. Duc de Brabant, cv. Woodbrige and cv. Russian Violet varieties are observed. The vegetative mass of shoots of cv. Speciosus, cv.Carneus Plenus and cv. Red Heart varieties increases more slowly. A conclusion follows, that the studied crop must take the deserving place in the assortment of decorative bushes of plant nursery farms
