Figure 2.

Wind- and light-induced changes in leaf heat transfer parameters of spring barley (Hordeum vulgare) and common bean (Phaseolus vulgaris). Measurements of dark-adapted leaves are indicated by closed symbols, and measurements of light-adapted leaves are indicated by open symbols. (A, B) Wind- and light induced changes in time constant (τ). Dotted lines represent the wind speed at which τ has decreased to 50% of its initial value (u_0.5) (C, D) Wind- and light-induced changes in difference between leaf temperature and ambient air temperature (T_L-T_a). (E, F) Wind- and light-induced changes in stomatal conductance (g_s). Error bars indicate standard deviation. For barley plants n = 9 individual leaves, for bean n = 10 individual leaves.
