Abstract
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.
본 연구는 기존 원예종에 비해 관상가치가 높은 반입종식물이 나타내는 반입현상의 다양한 변화를 측정할 수 있는 보다 정확한 검정방법을 개발코자 실시되었다. Scanning을 통한 컴퓨터 분석을 이용해 Tradescantia 2품종에 대한 전체엽면적 및 반입면적을 측정한 결과 광도가 증가할수록 전체엽면적은 감소하였으며 반입면적은 증가하는 결과를 나타내었다. 음지에서는 공시된 2품종 모두의 엽면적은 증가하였으며 반입면적은 급속히 감소하였다. 또한 위에 언급한 방법과 동일한 수법으로 광도에 따른 반입색차를 측정한 결과 양지에서 가장 밝은 엽색정도를 보였으며 광도가 감소할수록 엽색정도가 짙어졌다. 위의 결과에 대해 엽면적계로 전체 엽면적 및 반입면적을 측정한 값(
