Fig. 7From: Intercropping and environmental seasonality modulate the physiology and growth of Hancornia speciosa (Gomes)Multivariate analysis (PCA) and contributions of the gas exchange and biometric variables to the system (A) and season (B). Centroid and 95% CI for each season are showed. A—net carbon assimilation rate (μmol CO2·m−2·s−1); E—transpiration rate (mmol H2O·m−2·s−1); WUE—water use efficiency (μmol CO2/mmol H2O); Ci/Ca—internal CO2 concentration/ambient CO2 concentration ratio; gsw—stomatal conductance (mol·m−2·s−1); A/Ci—instantaneous carboxylation efficiency (μmol·m−2·s−1/μmol·mol−1)Back to article page
