| contents | Fig. 7. Leaf histochemical tests and crystals. A: Leaf blade cross-section (CS) showing presence of tannins in epidermal cells, guard cells and mesophyll cells (test FeCl3). B: leaf blade CS showing starch grains in mesophyll cells (test IKI). C: Leaf blade CS showing thin and striate cuticle (test oil red "O"); small crystals in parenchyma cells (arrows). D: Vascular bundle showing two secretory ducts containing polyphenols and resins (tests toluidina blue "O" and copper sulphate have been made). Abbreviations= cr: crystals; ep: epidermis; gc: guard cells; me: mesophyll; ph: phloem; po: polyphenols; re: resins; sc: striate cuticle; st: starch grains; ta: tannins; xy: xylem. Scales= A-D: 100 µm. |
