From: A global meta-analysis of woody plant responses to elevated CO2: implications on biomass, growth, leaf N content, photosynthesis and water relations

Fig. 5

Percentage change (± 95% CI) in photosynthetic characteristics (a–c), stomatal conductance (d) and water relations (e–f) of woody plants over different duration (years) of exposure to eCO2. The whiskers denote 95% CI and the circles denote mean percentage change (MPC) between aCO2 and eCO2. The numbers above the major ticks of the x-axis denote number of observations. The area fill ( ) shows the trends and the magnitude of differences between duration of exposure to eCO2. The wider the area the bigger the difference between MPCs. Key to duration of exposure: 0.5 years denotes half of a year (6 months)
