Course content

This course is offered every second year, next time in the autumn 2020. It builds on the foundation in plant physiology established in BI 1007 with an emphasis on ecophysiology. It covers the physiological processes involved in plant interaction with the environment, including water relations, gas exchange, energy balance, mineral nutrition, responses to the environment, plant defenses and stress physiology. These processes will be discussed with respect to current problems in agriculture and the environment such as crop and forest productivity and global change. The lab and project work includes measurements of water relations and hydraulic architecture, chlorophyll fluorometry and gas exchange, and frost tolerance. This course provides a physiological background for students studying plant ecology.

Learning outcome

On completion of the course the students should be familiar with basic principles and methods in plant ecophysiology.
The student will be able to:
Use a chlorophyll fluorometer and analyze and interpret chlorophyll fluorescence measurements
Use a pressure chamber to measure xylem and leaf water potentials and construct and interpret a pressure-volume curve
Make flow rate measurements in woody plant segments and use these to calculate hydraulic architecture parameters
Use image analysis software to measure leaf area and/or quantify visible symptoms of injury
Perform and analyze measurements for determination of frost tolerance in plant tissue based on relative electrolyte leakage or visible symptoms
Use a gas-exchange instrument for measurement of photosynthesis and respiration in plants and interpret the results
General competence:
The student will be able to:
Conduct and interpret measurements using a variety of instruments and methods
Analyze and present quantitative results in graphs and tables
Interpret results and draw conclusions based on them

Further on evaluation

All assessment components included in the course must be passed. In the case of 'fail' or 'retake' , the final written examination needs to be taken again. Appeals for reassessment apply to the final written examination only. The individual components will not be graded and assessment consists of an overall final grade. The written exam can be changed to an oral exam in the semester when the course is not taught.
Please refer to these supplementary regulations UTF §5-6 at NTNU for information on re-sit examinations (oral and written) in science courses.
1. Final examination in each semester -for courses with prefix BI, IT and KJ a final examination is held during the examination period every semester.
2. New assessment incase of “fail” - please refer to the course description for details on which components of the course need to be retaken in case of re-assessment.

Specific conditions

Exam registration requires that class registration is approved in the same semester. Compulsory activities from previous semester may be approved by the department.
