Quantitative parameters (μm) measured in leaves of P. maximum grown under different levels of [CO2] and temperature at Trop-T-FACE facility.

CUAD = adaxial cuticle thickness. CUAB = abaxial cuticle thickness. EPAD = adaxial epidermis thickness. EPAB = abaxial epidermis thickness. SCL = sclerenchyma thickness. MES = mesophyll thickness. LT = leaf thickness. BUL = polar length of bulliform cells. VASBU = polar length of vascular bundles. BSC = polar length of bundle sheath cells. VASDIS = distance between vascular bundles. Param. = parameter. ANOVA = p-values for significant effects: [CO2] (isolated effect of elevated [CO2]), T. (isolated effect of air warming), and [CO2] × T. (interaction of elevated [CO2] × Temp). [CO2] levels: aC (ambient [CO2], ~400 μmol mol-1) and eC (elevated [CO2], ~600 μmol mol-1). Temperature levels: aT (ambient temperature) and eT (2°C more than the ambient temperature).本数据集涉及的各测量指标定义如下：CUAD为近轴角质层厚度（adaxial cuticle thickness）；CUAB为远轴角质层厚度（abaxial cuticle thickness）；EPAD为近轴表皮厚度（adaxial epidermis thickness）；EPAB为远轴表皮厚度（abaxial epidermis thickness）；SCL为厚壁组织厚度（sclerenchyma thickness）；MES为叶肉厚度（mesophyll thickness）；LT为叶片厚度（leaf thickness）；BUL为泡状细胞极长（polar length of bulliform cells）；VASBU为维管束极长（polar length of vascular bundles）；BSC为维管束鞘细胞极长（polar length of bundle sheath cells）；VASDIS为维管束间距（distance between vascular bundles）。Param. 即参数（parameter）；方差分析（ANOVA）结果涵盖各显著性效应的p值：[CO2]代表升高CO₂浓度的单独效应，T.代表大气升温的单独效应，[CO2]×T.代表升高CO₂浓度与温度的交互效应。CO₂浓度设置水平包括：aC为环境CO₂浓度（ambient [CO2]，约400 μmol mol⁻¹），eC为升高CO₂浓度（elevated [CO2]，约600 μmol mol⁻¹）；温度设置水平包括：aT为环境温度，eT为较环境温度升高2℃的处理温度。
