The goal of this paper is the exploration of foliage distribution and light extinction in crowns of five canopy tree species in relation to their shoot architecture, leaf traits mean leaf angle, life span, photosynthetic characteristics and successional status from pioneers to persistent. Within each type, later successional species exhibited greater maximum LAI and total light extinction. In late successional species, leaf position within individual shoots does not predict the light availability at the individual leaf surface, which may explain their slow decline of photosynthetic capacity with leaf age and weak differentiation of sun and shade leaves. Since no leaf should exist below the light compensation point, the leaf area index LAI , the total leaf area per square meter of ground, is ultimately constrained by the pattern of light extinction in the canopy.

Since no leaf should exist below the light compensation point, the leaf area index LAI , the total leaf area per square meter of ground, is ultimately constrained by the pattern of light extinction in the canopy.
Typical LAI is in the range of 5—7 in temperate broad-leaved forests, and 6—8 in lowland tropical forests Leigh, Although herbaceous communities may have LAI as high as in forests, light utilization by forest plants differs from those in herbaceous communities in many aspects.
Vertical distribution of leaves takes place over a much greater distance in forests than in herbaceous communities, and this allows forest plants to exploit available light with a wide range of morphologies e. The great height of canopy trees in particular poses biomechanical challenges to optimize foliage distribution and to supply adequate amounts of water Borchert and Tomlinson, ; Niklas, Due to this complexity and the difficulty of reaching the canopy, analysis of light extinction through forest tree crowns as a function of cumulative LAI poses a much greater challenge than similar analyses for herbaceous communities.
Monsi and Saeki predicted that plants in full sun should have inclined leaves to achieve lower light extinction coefficients and high LAI to maximize canopy photosynthesis see Hirose, Greater inclination of not only leaves, but also terminal shoots, should result in more uniform distribution and efficient use of light in canopy tree crowns. In this paper is reported how light utilization characteristics of crowns of tall mature trees in a tropical forest vary among species in relation to differences in their architecture and leaf arrangement patterns.
Although irradiance generally decreases as one descends from the canopy of a tropical forest Yoda, ; Yoda et al. Koike and Syahbuddin concluded from their study of a West Sumatran forest that there is no continuous stratified upper canopy layer, but that the upper canopy consists of individual crowns that protrude upwards. Theories predict that architecture of tree crowns and patterns of leaf arrangement should affect the light extinction characteristics of the canopy Anderson, ; Horn, ; Kuuluvainen and Pukkala, Because solar tracks run near the zenith throughout the year at tropical latitudes, light exploitation characteristics of individual tree crowns should exert a greater influence on the light environment below them in tropical than in temperate forests Horn, ; Terborgh, Although significant effects of overall tree architecture e.

Wood is soft and light, and can be used for construction, tools, furniture and boxes. Cabinet 24 — Empire Timbers. Leaves are alternate and spiraling at the end of each branch; leaf blades are cm long and cm wide, widest near apex, forming an inverse teardrop shape. Beams 11 — Prospect: The wood presents attractive vessel lines. Canopy Family Panama The tree is common in the tropical and subtropical dry broadleaf forests of Pacific and Atlantic watersheds of Central and South America, extending as far north as Guatemala and south into Ecuador.
The branches support a huge diversity of epiphytic plants. Corteza exterior gris o negra, laminar, a veces con fisuras verticales profundas. They are arranged in inflorescence of loose, broad clusters at ends of branches.
They produce a strong, sweet, clove-like scent. Part I-Tropical American Species. Photo by Jenn Sinasac. Furniture, Common 23 — Handbook of Hardwoods. In the forest, a useful trait is the heavy leaf fall under the crown.
