CORRELATES OF LEAF OPTICAL PROPERTIES IN TROPICAL FOREST SUN AND EXTREME‐SHADE PLANTS

The purpose of the present study was to determine which leaf structures best correlate with previously published optical properties of 13 extreme-shade adapted understory species and 12 sun-tolerating tropical forest species. Additional measurements of these taxa have made it possible to determine if: 1) chlorophyll content is an important determinant of absorptance; 2) chloroplast distribution has a significant effect; 3) whether the effect is through flattening or path-lenthening, and; 4) whether other variables, as thickness, palisade parenchyma, cell dimensions, the extent of air spaces, and epidermal cell curvature, affect leaf absorptance
