Instructor: Dr.
William J. Bramlage
Semester: Spring
Lecture: MW 1:25-3:20
Laboratory: None
Credits: 4
Required Work: 2 exams, Final Examination
Course Description:
Learning the biochemistry and physiology occurring in harvested fruits,
vegetables, and flowers sufficiently to understand the processes occurring
inside them. Also, learning the principles and practices that apply to
