Biology and Genetics of Grapevines
A.Y. 2023/2024
Learning objectives
To give the specific knowledge of biology and physiology of the vine on the basis of those acquired during the courses of general biology and agronomy and preparatory course of growing techniques in viticulture.
To provide students with some knowledge of both theoretical and practical preparatory course of growing techniques in viticulture and enology.

Expected learning outcomes
Analytical knowledge of organography, phenology, physiology and ecophysiology of the vine to address basic study of viticulture.
Knowledge about the origin of the grown grapes, methods for their recognition, techniques for improvement of their quality and performance through clonal selection and crossing and how to address the varietal choices depending on soil and climatic conditions.

The life cycle and the annual cycle of the vine. Anatomy and morphology of the vine, Physiology of the development of the root system, of the vegetative and reproductive system. Rhythms of growth and activity. The correlative relationships. Physiology of development and fruiting. Differentiation and development of buds. From the differentiation of the buds to the fruit setting of the berries. Ecophysiology The carbon balance: photosynthesis and distribution of photosynthes. The water balance The nutritional balance and nutritional disorders. Physiology of grape development and ripening. The herbaceous phase, the veraison, the ripening curve, the sugar accumulation, the metabolism of acids, the nitrogenous substances, the polyphenols, the aromatic substances.
The genus Vitis and the main species of interest for viticulture. The domestication of the vine and the origin of the vines. The biodiversity of the cultivated vine. Intravarietal variability. Genetic improvement by clonal selection. Genetic improvement by crossing. Biotechnologies applied to the genetic improvement of the vine.
