Physiology of Plant Under Abiotic Stress

Credits: 2 Hours (2 lecture hours per week)

Instructor: Dr.ali Akbar Ramin, Department of Horticulture.

Attendance Policy:

You are expected to attend every lecture unless classes have been officially canceled by the University. Student who misses more than 4 class meetings will be dropped from the course. If you miss a class (with an excuse or by cutting), you are responsible for the material covered during that class. If the professor is more than 15 minutes late for class, the class is considered cancelled and the student may leave.
