COURSE CONTENT
Theoretical part
Botanical description of vine
Meristems and Morphogenesis
Phenological stages of vine development
Morphology of vegetative and reproductive organs (root, stem, tendrils, leaves, flower, rhizome, bract) and their evolution during the vegetative period (annual vegetative growth cycle)
Primary and secondary Anatomical structure of shoots
Morphology – Root anatomy
Developmental course and exogenous factors affecting morphology-anatomy
Fruit set, growth and ripening of the rails
Developmental physiology of the vegetative organs of the vine and exogenous factors that influence the development processes (lighting, temperature, water relations)
Developmental physiology of reproductive organs (effect of plant hormones, environment and nutrition on the different stages of flower development)
Endogenous and exogenous factors influencing the different stages of development, physiology and biochemistry of ripening with emphasis on the evolution of grape composition
The water management of the vine (study of the physiological processes of water absorption and transpiration as well as the effects of water stress on the growth and quality of the grapes produced)
Factors affecting photosynthesis and respiration in the grapevine, and how they are involved in the formation and metabolism of sugars
Inorganic grapevine nutrition: The requirements of the grapevine in inorganic nutritional macro- and micro-elements and nutrition-quality/quantity relationship
Abiotic stress factors of the vine
Laboratory Part
Primary & secondary anatomical structure of the shoot and its organs (tillers, buds).
Morphological & anatomical characteristics of the leaf.
Root morphology & anatomy.
Morphology & anatomy of the flower
Morphology & anatomy of shoots
Photosynthesis – Photosynthetic pigments (measurement of anthocyanins, analysis of photosynthetic and photoprotective pigments, measurement of photosynthesis and related parameters).
Transpiration (study of the parameters on which transpiration depends, leaf transpiration rate, stomatal conductance).
Respiration (study of the function of respiration in vine leaves and determination of the respiratory quotient).
Storage polysaccharides (determination of starch in roots and leaves of vines of different age – location on the stem).
Quantification of total nitrogen (quantification of total nitrogen in vine leaves of various ages).
