Popis: | Switchgrass (Panicum virgatum L.) has potential as a sustainable biofuel crop. Utilizing alternative sources of fertilizer nutrients could enhance production of switchgrass. However, alternative sources of fertilizer such as sewage sludge sometimes contain heavy metals such as cadmium (Cd) and the response of switchgrass to Cd is not known. Four switchgrass cultivars (Alamo, Blackwell, Cave‐in‐Rock, and Trailblazer) grown in sand culture were watered twice weekly with a nutrient solution containing Cd. Cadmium levels in solution were 0, 1, 2, 4, 8, and 16 mg Cd L‐1. Plants were harvested 63 d after planting and separated into leaf blade, stem (culm + leaf sheath), and root components. Tissue Cd concentrations were determined using atomic absorption spectrophotometry. Cultivars differed (P |
