FIGURE 10. Cross-section of a leaf blade of Copaifera marginata Benth. submitted to histochemical tests. a, e, i, n, o petiole. b, c, f, j, k, m rachis. d midrib. g, h, l leaf blade. a–d lignin in the xylem vessel elements, hypodermis cells, fibers, and sclereids. e–g total alkaloids indicated by arrows. h–l reducing sugars in tissues and in the epithelial cells of the secretory cavity, indicated by arrows. m–o phenolic compounds in the tissues and epithelial cells of the secretory cavity, indicated by *. (c = cuticle; fi = fibers; ep = epidermis; et = secretory epithelium; hy = hypodermis; lu = lumen; ph = phloem; pp = palisade parenchyma; sc = sclereids; st = secretory cavity; sp = spongy parenchyma; tr = trichome. xy = xylem). Scales: a, i, m = 200 µm. b-h, j, l, n = 50 µm; k, o = 20 µm.
