6 - Variation Due to Leaf Structural, Chemical, and Physiological Traits


Changes in leaf internal structure may affect leaf optical properties to varying degrees in different parts of the solar spectrum, but they are most evident in the near infrared (NIR) where absorption by pigments is minimal. The mesophyll anatomy of leaves of terrestrial plants is highly variable. To illustrate the effect of such variability on leaf optical properties, Gausman et al. (1971c) selected 11 species displaying a wide range of internal structures (compact, dorsiventral, isolateral, and succulent) and thicknesses.
