Figure 2.
Combined effects of temperature and water availability on net photosynthetic rate (A), stomatal conductance (B), intercellular CO2 concentration(C) and Ci/Ca ratio (D) of Stipa baicalensis. T, Temperature treatment; W, Precipitation treatment. Vertical bars represent ± SD of the mean (n = 3); Different letters on the SD bars indicate significant differences among the treatments (p < 0.05). ns, No significant differences. *Indicates significant differences at p < 0.05. **Indicates significant differences at p < 0.01.
