Correlation of stomatal conductance and transpiration rate with measured independent variables. The independent variables included (A) environmental variables: temperature of a non-transpiring plant (Tdry), photosynthetically active radiation (PAR), black sphere temperature (TBS), air temperature (Ta), relative humidity (RH) and vapor pressure deficit (VPD) measured in the growth zone (gz), and inside (in) and outside (out) the cabin, (B) thermal infrared indices (Table 1), and (C) relative reflectance at 532, 992, 1407 and 1881 nm and hyperspectral indices (Table 1). Significant (P < 0.05) correlations are indicated in blue (positive) and red (negative). gs stomatal conductance, E transpiration rate
