Analysis of Ecophysiological Response Curves Obtained from Experiments

Description: Photosynthetic rates (CO2 Uptakes) for 2 plant
populations (Quebec and Mississippi), under 2 treatments (control and
chilled), at 7 CO2 conentrations (95, 175, 250, 350, 500, 675, 1000 muL/L).
3 Reps at each pop/trt combination. Data entered as uniivariate
response (one line per plant per CO2 concentration)
