Effect of photosynthetic photon flux at 25°C (above) and air temperature at 1000 μmol m−2 s−1 PPFD (below) on tomato crop photosynthesis and transpiration under unlimited water supply. Relative humidity of the air is always 70%, thus vapor pressure deficit is decreasing with temperature. Data are derived using a crop growth model (Kläring and Bar-Yosef, 2006).
