Figure 1

Short-term flooding: Mean values averaging over 5 minutes during day time (Day time averages) for Assimilation (A) in μmol m-2 s-1, transpiration (Tr) in mmol m-2 s-1, stomatal conductance (gs) in mm s-1, leaf internal CO 2 concentration (Ci; ppm) with their standard deviations (SD) and Standard emissions (E s ) of monoterpenes and isoprene. Data are derived from two individuals each of Hevea spruceana (n = 142 per day) and Vatairea guianensis (n =142 per day) from várzea (light grey) and igapó (dark grey) given on a dry weight basis in μg g-1 h-1 ± SD. The significances of the differences between nonflooded (nf) and 1, 2, 3 and 4 days flooded (df) were tested with ANOVA and the Tukey Test; * = P-value < 0.01 F ratio is significant, ** =,P-value < 0.001 F ratio is very significant. *** = P-value < 0.0001 F ratio is highly significant.
