“(…) Maximum temperatures of 40.8 °C (InT) and 38.6 °C (ExT) (Figure 3) were recorded in the same period as for photosynthetically active radiation, at 1 pm and 12 pm. In contrast, internal and external relative humidity drastically reduced during the highest irradiance (PAR) and air temperature (InT and ExT) periods, with minimum at 2 pm (InRH = 30%; ExRH = 32%) and maximum at 8 am and 5 pm (Figure 3).

“(…) On the other hand, maximum values were recorded earlier in the day (8 am) (89.28 electrons quantum-1 in T. roseoalba and 60.70 electrons quantum-1 in H. heptaphyllus). Thus, ETR increased approximately 73% in T. roseoalba and H. heptaphyllus compared to the lowest values observed (Figure 5E).
