Table 4 Species transpiration [average ± SD in mm day⁻¹ m⁻² leaf area (LA)] for the different modalities of radiation and REW levels and the three sessions. Lower case and upper case letters indicate statistically significant difference between modalities for the same session and between species for the same modality, respectively (ANOVA, P < 0.05). Outdoors treatment was not included in the analysis
