Numeric description of color using CIELAB color space. L* (lightness or darkness) ranges from black (0) to white (100); a* color direction in red (a*>0) or green (a*<0); b* color direction in yellow (b*>0) or blue (b*<0); ΔE (the total color difference) is calculated based on delta L*, a*, b* color differences and represents the distance of a line between the germination day and initial day.
Mean±SD (n=3) followed by different letters are significantly different according to germinated time (p<0.05).
