Viticulture Course content Diffusion of wine grape cultivation in European and extra-European countries. Regional situation in Italy. Main species of the genus Vitis and their origin, use and distribution. Organography: permanent wood, types of buds, the shoot, the inflorescence, the bunch, the berry, types of growth of the root system. Main components of grape berry: sugars, organic acids, polyphenols, aromatic substances, stilbenes. Methods of characterization of species and varieties, ampelography and ampelometry, OIV descriptors list. Management of data and characteristics of Italian and European Vitis databases. Technical objectives of conservation of the grape germoplasm. The clonal selection. Annual cycle and phenological phases of the plant: flower induction and differentiation, bud dormancy, fertility, development of the shoot and of the berry. Grapevine propagation: in vivo and in vitro techniques, problems and objectives. Organization and regulations of nursery plant production. Rootstocks: selection criteria in relation to the environment and variety. Influence of climate and soil on plant growth and on the main qualitative parameters of the grapes. Main bioclimatic indices. The photosynthetic process and relation to environmental and endogenous factors. Criteria for choosing varieties and clones in conventional and organic viticulture. Plant response mechanisms to biotic and abiotic stresses, isoidric and anisohydric grape varieties. Vineyard management: winter pruning, acrotony management, fertility and its distribution on vine cane. Main trellis training systems. Main vegetative-productive indexes. Direct and indirect methods of vigor assessment, the use of precision viticulture. Soil management techniques. Green pruning management and its influence on berry quality. Prediction of grape harvest: grape sampling techniques and analysis of main qualitative parameters. - Practices: they will be carried out mainly at the Experimental Farm of the University of Tuscia and will focus on ampelography and agronomic management of the vineyard.
