RT Journal Article SR Electronic T1 Variations in Leaf Coloration Using a Reflectance Colorimeter JF Arboriculture & Urban Forestry (AUF) FD International Society of Arboriculture SP 157 OP 159 DO 10.48044/jauf.1982.037 VO 8 IS 6 A1 Kwolek, W.F. YR 1982 UL http://auf.isa-arbor.com/content/8/6/157.abstract AB Leaf coloration for 9 plant species measured with a Hunter colorimeter showed major variations between plants and leaves within a plant, but minor variations associated with reading position within leaves and instrument. The lower leaf surface was more sensitive to color differences. The magnitude of variation between leaves was dependent on species. The colorimeter provides quantitative information for comparing plant leaves.
