Light Quality & Intumescence Development
These lessons explore a phenomenon associated with light quality--the development of intumescence in tomato when UVB light is absent. Lessons may augment modules in, for example, Cell Biology, and serve as a way to introduce careers in controlled-environment horticulture to high school students.
