Problem 1
What are the basic differences between too much light and too little light in terms of plant response? What are some of the ways of compensating for either extreme in the design of an agroecosystem?
5 step solution
Problem 2
Our understanding of the different types of photosynthetic pathways in plants has come mostly from basic laboratory research, but this knowledge has helped considerably in the management of the light environment in agroecosystems. What other basic research questions, greatly isolated from the field, might be of great potential significance for sustainability?
