Figure 2 Impacts of growth temperature, water regime and
heatwave on the ratio of intercellular to atmospheric
CO2 (Ci/Ca; panel a, b)
and leaf level carbon balance represented by the difference between
rates of photosynthesis and dark respiration
(Asat-Rn; panel c, d) of cotton plants.
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.
