Rein casting method was applied to the wood anatomy of some Japanese hard-and softwoods. Dry wood blocks were impregnated with resin. Several kinds of synthesized polymers, such as polystyrene, polyester, epoxy resin, and polymethacrylate, were tried.Cell wall materials were completely removed with alternate and repeated treatments with hydrogen peroxide/acetic acid solution and sulfuric acid. Resin-casts were treated with ultrasonic in water to remove extra resin-casts of xylem elements, coated with Pt-Pd, and then observed in a scanning electron microscope. The resin-casts obtained were composed of vessels, other xylem elements contacting to a resin base, and paratracheal elements connected to vessels with intensive pitting. All xylem elements were observed in their original arrangement.
