Figure 4

Nonstructural carbohydrates content of Impatiens New Guinea grown under two CO₂ concentration: ambient CO₂ (380 μmol·mol⁻¹) and elevated CO₂ (760 μmol·mol⁻¹). Asterisks show statistically significant differences (^∗𝑃<0.05; ^∗∗𝑃<0.01; Student’s t-test; 𝑛=3 samples, with 5 plants per sample) and the bar is the standard deviation. Total NSC= soluble sugars + starch.
