The Reflection of Visible Radiation from Leaves of Some Western Australian Species

Abstract

A spectrophotometer with an integrating sphere-reflectance attachment was used to determine total reflectances of leaves after irradiation with visible light of wavelengths ranging from 340 to 620 m/,-, Reflectance measurements were made at 20-m/,- intervals in this range. The leaves of 32 Western Australian plant species were studied, and where upper and lower surfaces were different these were con· sidered separately. No significant differences were found between the reflectanceR of leaves from different topographic areas.
