Figure 5 Recovery of leaf gas exchange variables following
heatwave stress in cotton plants. Rates of light saturated
photosynthesis (Asat; panel a, b), stomatal conductance
(gs; panel c, d) and leaf carbon balance
(Asat-Rn; panel e, f) were measured
after plants were placed under their prevailing growth temperature for
two days following the 5-day heatwave treatment. Bars indicate mean
value for each treatment combination and error bars represent standard
error of mean (n=5). Thermal regimes characterized by different daytime
temperature (i.e. 32/22oC and
32/26oC) are indicated by hatched bars.
