Abstract

Growth cycles and production of aboveground and belowground giant cutgrass ( Zizaniopsis miliacea (Michx.) Doell and Asch.) were studied in a freshwater tidal marsh along the lower Savannah River near Savannah, Georgia, USA. Minimum aboveground live standing crop (142 g/m 2 ) occurred in March with a steady increase thereafter to an October maximum (1,039 g/m 2 ) followed by a rapid decline. Giant cutgrass aboveground net primary production was approximately 1,530 g/m 2 /yr. Rhizomes (358 g/m 2 /yr) and roots (160 g/m 2 /yr) yielded an annual belowground production of 518 g/m 2 /yr. Total above and belowground annual net production was estimated at 2,048 g/m 2 /yr.
