Learning Objectives
Knolewdge acquired: concepts that form the basis for understanding the
viticulture from botanic to ecology and physiology.
Competence acquired (at the end of the course): understand origin of
viticulture vine ecology and application of cultural management for the
correct vineyard management
Skills acquired (at the end of the course): “terroir” suitability to vine
growing evaluation, as well as vineyard efficiency evaluation, corrective
treatments to improve efficiency.

Course program
Sistematic of grapevine, history, genetics and genetic improvement. ):
General information about viticultural ecology. Biological factors: variety
and rootstock. Climate effect: light, temperature, rain, bioclimatic indices.
Climate factors: latitude, altitude, exposure, sea, lakes and rivers,
problems by frost and hail. Soil: soil composition and grape quality. Effect
of physical soil characteristics on grape quality. Effect of chemical
composition. Environment choice: zoning and terroir. Modern zoning
organici e successiva degradazione; composti azotati, pectine, composti
fenolici: biosintesi, evoluzione durante la maturazione, condizioni di
accumulo. Sintesi di sostanze aromatiche
systems: macro- meso- and micro-zoning. Cultivar-environment
interactions. Pedological studies, links between soil and biological
features. Study of biological system.
Physiology: description and behaviour of grapevine organs; roots, shoots,
buds. Annual and vital cycle. Vegetative and reproductive cycle.
Root growth and development: external and internal factors. Water and
nutrient uptake, effect of water status on vine physiology, nutrient
availability and uptake. Nutrients and water deficiency: symptoms and
diagnostic.
Shoot growth and development: effect of temperature, water and
nutrients, light and photoperiod. Water relations, hormonal balance,
transport system. Intrinsic characteristics: acrotony, lateral development,
dynamic of growth.
Photosynthesis: effect of physical factors. Light, CO2, temperature, water,
air humidity. Biological factors: stomata, sugar accumulation, leaf age,
genetic aspects. From single leaf to whole canopy: light interception,
shaded leaves activity. Measure of leaf surface, effect of several
techniques on exposed leaf surface; canopy efficiency and evaluation.
Photosynthesis products translocation: general characteristics, sap
composition, mechanism and transport velocity. Transport along the
shoot, role of growth regulators, other variability factors. Effect of graft
and shoot position.
Net photosynthesis and carbohydrate partitioning, storage and soluble
sugars, starch synthesis.
Berries formation and development: flower induction, flowering, hormonal
balance, growth factors. Metabolism and biochemical factors: respiration,
organic acids formation and degradation, nitrogen compounds, pectins,
phenolic compounds. Biosynthesis, evolution during ripening,
accumulation. Aromatic substances synthesis.
