Figure 5From: Can differences in phosphorus uptake kinetics explain the distribution of cattail and sawgrass in the Florida Everglades?Experimental chamber used for uptake studies. Schematic diagram of the experimental system used to estimate the plant P uptake showing the connection between the plant chamber and the flow injection analyzer (FIA) used for PO4 3- detection. 1: Acrylic root chamber with diffuser for flushing with air or N2; 2: Collar and seal for plant mounting; 3: Magnetic stirring bar protected by a net; 4: High speed peristaltic pump for recirculation of solution in the root chamber; 5: Tee pieces; 6: Three-way valves for calibration of FIA; 7: Peristaltic pump of the FIA; 8: Six port valve of a FIA analyzer channel.Back to article page
