Syllabus
Prerequisites: No specific prerequisites are strictly needed, but a basic knowledge of Calculus, General Physics, and Plant Physiology is requested, as given in most of graduate courses.
Examination methods: The examination will be based on: a) a mid-term presentation by the student on a key topic selected among a range of papers propsed by the teacher; b) the write-up of a technical report on the data collected during the practical work; c) a final oral colloquium.
