A summary of the major physiological traits determined by analysis of leaf gas exchange of plant exposed to various CO2 and light treatments, as in Figures B and C in S1 File.

Respiration values were calculated as the average of 3 replicates when the light level was 0 μmol m-2 s-1, the light compensation point, and quantum yield were calculated from a regression line (y = mx+b) fitted to the values between the light levels of 0–100 μol m-2 s-1. The photosynthetic max (Pnmax) was calculated from f = yo+a(1-e(-b*x)). Note, quantum yield and Pnmax are given on a leaf area basis and a chlorophyll basis to show the difference when expressing data on two different normalization factors.当光照强度为0 μmol·m⁻²·s⁻¹时，呼吸值以3次生物学重复的平均值计算；光补偿点（light compensation point）与量子产额（quantum yield）则通过拟合于0~100 μmol·m⁻²·s⁻¹光照区间内数据的回归直线（y = mx+b）计算得到。最大净光合速率（photosynthetic max, Pnmax）通过公式 f = y₀+a(1-e^(-b·x)) 计算得出。需注意，量子产额与Pnmax均分别基于叶面积和叶绿素含量进行归一化处理并给出结果，以体现采用两种不同归一化因子时的数据表达差异。
