This study was carried out to investigate the effects of light intensities on the growth and net photosynthesis of Piper kauzura under different shading levels : 0%, 50%, 70% and 90% of sunlight. Mortality rate was lowest under a 70% shading level but 0% and 90% shading levels were about 46% and 53% each respectively. Plant height was shorter and leaf size was smaller and yellowish under a 0% shading level but increased when light intensity was decreased. However, under a 90% shading level, growth of Piper kauzura was inferior to other treatments. Top fresh weight was about 11.24g under a 50% shading level and about two times higher than that observed in about 6.6g under a 90% shading level. Root fresh weight was about 7.7g under a 0% shading level and was about two times higher than that showed in about 3.84g and 3.64g under 90% and 70% respectively. Total chlorophyll content and chlorophyll a/b rate were increased when light intensity was decreased. Net Photosynthesis achieved the highest under a 70% shading level and maximum photosynthetic photon flux density was 150 molㆍm/sup -2/ㆍs/sup -1/. Therefore, growth of Piper kauzura was good under 50∼70% shading, Meaning that it is an indoor plant that could be highly utilized.

This study was conducted to investigate the growth responses of Polystichum lepidocaulon as influenced by 4 different shadings(Control, 50%, 70%, 90%). Under 50 or 70% shading, plant height, stipe length, blade length, blade width, and number of spores increased compared with the other shadings, except the number of frond and shoots. The plants grown under control was shown as smaller with more yellowish green leaf color, and under 90% shading the growth was slightly inferior to those under the 50 or 70% shading. Fresh weight and segment area of frond was better in increased shade levels, but they decreased in under 90% shading. Dry weight and segment thickness decreased as shading increased. Chlorophyll contents increased in proportion to lowered light intensity. Thus, 50 or 70% shading of Polystichum lepidocaulon seemed to maintain the highest growth.

This studies has been performed to see proper environmental conditions and possibility of landscape use of Pteris multifida in native evergreen fern. The resulsts wewe summarized as followed. Considering the ornamental value, Pteris multifida was shown steady growth on the whole part of top and kept best. But in the half shade, it was so partly browned leaves that ornamental value was decreased prominently and the leaves shaped thinner than in the shade. In the sun, it was almost dead on the top part. The chlorophyll contents was getting down from the shade to the sun, and the number of damaged leaves was nothing in the shade, but was increased to 43% in half shade and 96% in the sun, and the browning of leaves was increased as the lightness is going up. As a result, Pteris multifida gets the best growth as provided low light and proper water supply such as high humidity and low loss of water content at the soil, ets. And especially it is considered that low light of 1,500lux is at the prior environmenal condition for a ground cover material in outer on Pteris multifida.
