Subject description
Specific use of several agro-ampelotechnical measures adapted to different cultivars and technological ripeness of the grapes in regard to environmental conditions or optimal vineyard position. Selection and choice of vine rootstocks, cultivars (clones) and cultivation methods (conventional, integrated and organic agriculture) with special emphasis on environmental pollution of each production type, particularly the accumulation of heavy and transitional metals into vineyard soils. The definition of grape quality and its effect on the quality of wine and sensory management. The course content will also include the knowledge on specific measures for cultivation of table grapes: innovations, technologies, current legislation and the possibility of production in Slovenia. From the field of grapevine nursery students will be acquainted with the newest production technologies of grafted vines, new grapevine selection, grafting process and maintenance of stock/grafted plants from spring to autumn. The student will understand the importance of optimal selection of rootstock as these can mitigate the negative effects of environmental conditions. The significance of viral and other diseases on the production of grafted plants will be discussed along with the measures for infection prevention and the spread of diseases and pests from plant to plant. Thus, the student will acquire knowledge of the biodiversity of species, cultivars and clones and the possibility of their adaptation to changing environmental conditions. The site parameters affecting growth, yield and grape quality will be presented and the potential of vineyard practices to moderate the negative and exploit the positive effects of the environment explained. Internal grape quality will be defined as the content of specific primary and secondary metabolites. Technological measures to produce optimal quality grape will be stated.
