Spectral Energy Relations of Isobilateral Leaves

Abstract

Heflectance and transmittance have been studied for eucalypts in the spectral range from 4000 to 9500 A at varying angles of incidence. Spectral reflectance and spectral transmittance were observed to be high in the infrared. All leaf surfaces were found to be highly diffusing and not to reflect white light in accordance with the sine law.
