Abstract
In order to elucidate growth characteristics, physiological responses and leaf color changes of leaf-variegated Arundinaria munsuensis and Carex ciliato-marginata for variegata, These experiments were performed under four different light ragimes control(full sun), 40%, 70% and 85%. Plant height and leaf area became promoted as shading level increases in leaf-variegated Arundinaria munsuensis. Photosynthetic effect was the highest in 85% shading of the full sun. Thus, this plant could be growing in the deep shade condition. Plant growth and the leaf color changes were most obviously shown in the 40% shading level. In the Carex ciliatomarginata for. variegata growth status was the best and green or strong greenish yellow leaf color turned out to be much clearer in the 40% shading treatment. And photosynthetic activity was enhanced as the light intensity decreases.
자생 잎무늬종 식물인 문수조릿대와 무늬털대사초에 있어서 광도차에 따른 생육과 생리적 변화 그리고 엽색의 변화를 알아보고 이들의 관상가치 증진에 알맞은 광도를 구명하고자 40%, 70%, 85% 차광구조건과 0%인 노지조건에서 4개월동안 실시한 실험결괴는 다음과 같다. 무늬종 문수조릿대(Arundinaria munsuensis)는 광도가 낮아질수록 초장과 잎의 크기가 증가되었고 차광 85% 조건에서 광합성효율이 높은 것으로 미루어 보아, 음지조건에서도 생육이 잘됨을 알 수 있었다. 그러나 40% 차광구(
