The present study was conducted to develop a more accurate and efficient measure than any other quantifying measures of the leaf variegation when influenced by changes in certain physical and environmental factors. Through this computer quantification for two Tradescantia cultivars, it was ascertained that total leaf area decreased and extent of the leaf variegation increased as light intensity increased. According to this result to determine the brightness of the leaf, using the same aforementioned measurement, the leaf color was brightest in the sun and it become darker as light intensity decreased. High correlation was found between total leaf and leaf variegation area measured by leaf area meter and the pixel of computer graphic file through scanning. Thus, the leaf area and leaf variegation area measurement using computer graphic will be used very efficiently.
