Teaching language

Suitable for English-speaking students

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.

Working method

Evaluation Type

Distributed evaluation with final exam

Assessment Components

designation	Weight (%)
Exame	75,00
Trabalho de campo	25,00
Total:	100,00

Amount of time allocated to each course unit

designation	Time (hours)
Estudo autónomo	49,00
Frequência das aulas	49,00
Total:	98,00

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 marks (75%) and a practical assessment, 5 marks (25%).

Classification improvement

The improvement will make will be entirely based on the quotation of the written examination (15 marks).

Observations

To be admitted to the exam students must have positive note (2.5 marks out of 5 marks) in the practical assessment.

Students must have a positive grade in the final exam, equivalent to 7,5 marks (out of 15 marks).

To pass this course, students must have a final grade of 10 points, corresponding to 2.5 points in the practical evaluation and 7.5 points in the final examination.
