 note = {In this study, it was tried that the leaf-color-change (turning red or yellow) of the tree was evaluated using the colorimeter. The results of this study consist as follows: 1) The chromaticity measured by the colorimeter was correspondent to the change of the color judged by the photograph. The tendency was remarkable of the leaf-color-change of Ginkgo biloba and Acer palmatum. 2) In the observation, leaf-color-change was evaluated using chlorophyll meter (SPAD value) with measurement of the colorimeter. The decrease of SPAD value was correspondent to the change of the value of the chromaticity. Therefore it is considered that the value of the chromaticity of Acer palmatum is possible to be related to the increase in the red pigment, namely the anthocyan. From the above fact, the observation using the colorimeter is verified with that it is effective as a method for evaluating the leaf-color-change.},
