Figure 9.

Light absorption profiles in Juglans regia and Juglans microcarpa leaves irradiated with direct monochromatic light at blue (488 nm), green (532 nm) and red (650 nm) wavelength under well‐watered (solid lines) and dehydrated (dashed lines) treatments averaged over four replications (n = 4). Directional lights were illuminated from adaxial (a and b) and abaxial (c and d) surfaces. Relative fluorescence (%) is presented relative to the illumination direction, adaxial (a and b) or abaxial (c and d) [Color figure can be viewed at wileyonlinelibrary.com]
