Figure 4 Growth rate (as defined by plant height) of cotton plants exposed to different growth temperature, water and heatwave treatments. Rate of growth is quantified by the days required for plant height to reach 50% of its maximum. 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.
