Figures & Tables

Fig. 1

Trend of climatic data during the days of experiment: Temperature (closed circles), vapor pressure deficit (VPD, open circles), and global radiation (RG) are shown. Error bars for each average value of temperature and VPD come from 3 measurements, taken at the hours of the day with highest radiation (11:30, 12:30, and 13:30). RG values refer to the interval 11:30–13:30

Leaf area by species. Values marked with the same letter are not statistically different at p < 0.05, according to Duncan's multiple range test. Error bars were calculated from six measurements (replicates) for each average value

Linear correlation between measured and calculated stomatal conductance; for each species, a single regression line, with slope and R2, is presented in the graph; the central dotted line represents the ideal 1 : 1 relationship between measured and calculated gs
