“The ability to attain the feedstock production goal in the USA for biofuel production is limited by available arable land, cool temperatures, and periods of low light intensity. This study investigates the effects of warm and cool temperatures growth conditions in a low light regime on the photosynthesis and growth of switchgrass (Panicum virgatum cv. Alamo) and giant miscanthus (Miscanthus giganteus). Alamo switchgr…” Show full quote
