“…The presence of axial canals in the stem of C. langsdorffii has been described by several authors (Marcati et al 2001;Langenheim 2003); however, this is the first report on the occurrence of secretory canals in the root wood of C. langsdorffii.…”

“…According to Langenheim (2003), these chemicals confer ecological versatility on producer plants and ensure protection against herbivores and pathogens. According to Pinto et al (2000), the volatile fraction of the resin produced by Copaifera species is composed of sesquiterpenes, while diterpenes are responsible for its non-volatile fraction.…”

Copaifera langsdorffii Desf., popularly known as copaíba, is an oleoresin-producing tree has been overexploited in Brazil by the pharmaceutical, cosmetic and varnish industries. Despite the long history of the use of this species, the structural knowledge on the resin-producing sites remains inadequate and is limited to the trunk. The aim of this study was to describe the origin, structure and developmental features of secretory spaces present in shoot and root wood of C. langsdorffii, based on the usual techniques of wood anatomy studies. Both root and shoot wood present secretory canals distributed along the marginal parenchyma bands which delimit growth layers. Secretory canals are constituted by a locally biseriate epithelium and lume that contains terpenes. They are arisen in the cambial zone from fusiform cambial initial cells and, eventually, ray initials. The origin of lumen is schizogenous. The epithelial cells have meristematic potential and are responsible for the locally biseriate epithelium. Mature secretory canals are wider and are separated between themselves only by a row of radial cells. The fusion of these adjacent secretory canals is frequent and results from the radial cell collapse. The finding of an interconnected system of resin canals in C. langsdorffii might be of value in terms of sustainable extraction of the resin and realistically assess its sustainable harvest potential.

“…In all the organs of C. langsdorffii studied, the internal glands originated schizogenously, as described for different legume genera (Langenheim et al, 1978;Marcati et al, 2001;Metcalfe and Chalk, 1950;Solereder, 1908;Turner, 1986), although schizolysigenesis occurs throughout their development, as discussed below.…”

Measurement of the size (volume), distribution, and density of resin pockets are compared in margin and center areas of leaves in 11 species (including six varieties of two widespread species) of Hymenaea. Resin composition and yield (mg/g leaf tissue) were analyzed by gas‐liquid chromatography. Resin pocket patterns in certain species are highly distinctive; also a relationship seems to exist between patterns of closely related species, with variation having occurred in species or populations of widespread species which have radiated into different kinds of habitats. Thus these patterns may provide useful taxonomic characters, but we suggest that some of the patterns (and thus composition and yield of resin of different portions of the leaf) have evolved under selective pressures of herbivorous insects.
