Learning outcomes

The course consists of two modules. The General viticulture module introduces to the knowledge of the grapevine cultivation in the basic aspects related to taxonomy, ampelography, genetic improvement, propagation of vine. The module of Viticultural ecology and physiology examines the aspects of viticulture linked to the environmental and biological parameters that characterize the areas of cultivation of the vine.

Syllabus

The history of the vine. The systematics of the genus Vitis. Characteristics of the main species and their utilization. The rootstock of the vine and recent genetic acquisitions. The ampelography and ampelometry. Molecular methods for varietal identification. The grapevine main varieties red, gray, white, and their attitudes. The grapevine germplasm and its exploitation. Genetic improvement of wine grape by vegetative way: the mass and clonal selection. Genetic improvement through sexual methods : the IPD, intraspecific crosses. The grape propagation methods mostly used.
Ecological factors influencing grapevine development and conditioning the grapevine cultivation areas. Bioclimatic indices. Annual and life cycle; vegetative and reproductive sub-cycles. Phenology and factors impacting on phenology. Climate change. The bud complex. Inflorescence induction and bud fruitfulness. Bud dormancy. Partenocarpy, stenospermocarpy. The grape cluster, anatomy of the berry. Classification, characteristics, biosynthesis, tissue localization of the major compounds of a ripe berry, and their changes during berry growth and ripening. Regulation of development and ripening of the grape berry.

Assessment methods and criteria

General viticulture module. Final exam is oral and aims to verify the knowledge of the subjects analyzed during the course. The oral examination will focus on the topics covered in the lesson. The student's preparation will be assessed on the basis of: (i) knowledge and in-depth study of the topics dealt with; (ii) exhibition capacity; (iii) correctness of technical-scientific language.
Viticultural ecology and physiology module. The exam is oral for both students following and not following lectures. The test potentially covers all programme topics.
The final vote will be represented by the arithmetic mean of the votes of the two modules and will be expressed in thirtieths.
