Notes	A single wavelength reflectance method at 680nm. the chlorophyll absorption band, was used as a means of separating Satsuma oranges in the packinghouse line according to their ripeness and internal quality (sugar and acid content). As the correlation between this grading index and the color index evaluated by human judgement was high, this measurement method was found to be useful for color index evaluation. As spectral reflectance decreases with the lapse of time after picking, the fruits should be graded as soon as possible.
