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.
