摘要
Mn, Fe, Cu, and Zn in shoot tissue of Spartina alterniflora Loisel. were analyzed for seasonal trends and relationships to dry matter standing crop. Two brackish marshes in Virginia were sampled four times between April and September 1975. Between early April and late May shoots accumulated Mn, Cu, and Zn at a faster rate than dry matter standing crop increased. Fe followed this trend at Bennett's Marsh but matched standing crop increase at Taskinas Marsh. Tissue concentrations of Mn, Cu and Zn declined over the growing season at both marshes; Fe declined at Bennett's Marsh and increased at Taskinas Marsh. © 1979.
