Learning Objectives
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.
Prerequisites
Knoledge of Chemistry, Vegetal Biology and Agronomy
Teaching Methods
Frontal lessons and via moodle, seminars with experts, practices in vineyards, visits to leader wineries. Considering the COVID situation, all the lessons are made by internet, uploading records on MOODLE platform, where has been activated a discussion forum for both lesson topics and actuality topics. Under request is possible to organize virtual meetings by G-meet platform.
Further information
Complete learning material on Moodle platform
Type of Assessment
Oral exam. Considering the COVID emergency, all the exams are made by internet using the G-meet platform following the directions of the Dean.
Course program
Course Contents (detailed programme):
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 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.
