초록
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(
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.
