Effects of elevated CO2 on plant growth and its structure with water status gradient. a plant biomass; b leaf area; c LAR, leaf area and plant mass ratio; d LARMR, leaf area and root mass ratio. W−60, W−30, W−15, W0, W15, W30, and W60 represent −60 %, −30 %, −15 %, 0 %, 15 %, 30 %, and 60 % of watering relative to mean precipitation in the local site over 30 years. A GLM ANOVA between temperature and watering, and their interaction was show in Additional file 3: Table S2. Different lower case letters indicate differences between watering treatments across the two CO2 levels at P < 0.05 according to Duncan multiple range test. Vertical bars denote SE of the mean (n = 3–4)
