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.
