Attempts had been made to differentiate jack pine from some common eastern Canadian conifers (balsam fir, tamarack and black spruce) by analyzing the color appearance from three different chemical tests on wood. The tests conducted were based on either the major extractives (ferric chloride test), the pH (bromophenol blue test) or the resin acids (phenol/bromine test). The chemical tests work only on the heartwood; they do not work on sapwood. The results indicated that the measurement of CIE L*, a*, b,* color parameters is a useful and rapid means for differentiating jack pine from other conifers studied. The test results can be obtained in 10-15 min when wood flour is used. |
