Objectives
Understanding the physiological mechanisms of interaction between development and plant production and the biotic and abiotic factors, to develop appropriate cultural practices and understand the management options.
Learning outcomes and competences
Knowing the physiological mechanisms that result in an adjustment of growth when the plants are exposed to changes in their environment.

Eligibility for exams
Students must have 75% attendance of the theoretical classes and 75% of the frequency of practical classes.
Calculation formula of final grade
The evaluation will consist of a theoretical assessment and a practical assessment.
The theoretical evaluation worth 15 points (75%) and a practical assessment, 5 points (25%).
Classification improvement
The improvement will make will be entirely based on the quotation of the written examination (15 points).
Observations
To be admitted to the exam students must have positive note (2.5 marks) in the practical assessment.
Students must have a positive mark on the final exam, equivalent to 8 points out of 15 points.
