Aim of the course and learning outcomes:
The course is aimed on the reaction of the woody plants on the mechanical loading and on the influence of the mechanical loads on wood structure and plant body morphology. Then the students will be able to assess mechanical sufficiency of a tree.

Assessment methods:
Exam is oral. For entering the credit and the project (an essay or literature review) are demanded. The project topics are like: Thigmomorphogenesis, Adaptive growth of the above ground part of the wooden plants, Pasive mechanisms of tree stability. The project defines 50 % of the mark, the discussion 50 %.
