Objectives
The UE HAW703 aims to transmit to the students knowledge on the development and the functioning of the tree by an integrative approach. The biological cycle of the tree is thus approached through the implementation in space and time of its architecture, its anatomy, and the great functions realized. Diversity is addressed through examples of Mediterranean, temperate and tropical species and their adaptations to their environment.
Targeted competencies
Understand and describe the architecture of the tree by analyzing its primary and secondary growth.
Identify genetic and environmental parameters that influence primary growth, cambial function and duraminization.
Differentiate between the main species in the field and in beds
Perceive the adaptations of trees to climate change.
