자생 상록‘고사리목 식물’의 광적응성 및 실내조경공간도입방안

Abstract

This study was performed to research the adaptability of the light environment for the native evergreen ‘Filicales plant’ growing naturally in Jeju Island and the southern coast of Korea, and to provide the introduction plan into the interior space. The experimental plants were Polypodium vulgare L, Polystichum lepidocaulon(HOOKER) J. SMITH), and Rumohra aristata (RORST) CHING, and the plants were bought from the farmhouses in Jeju Island, and in the southern coast, purified at of Jinju National University for 30 days, and then the experiment was done in the greenhouse of Horticultural Department at General Farm of the University from February 15, 2009 to October 15, 2009. The main lighting type was fluorescent light, and the irradiation was performed continuously for 12 hours per day under 100lux, 500lux, 1,000lux, 2,000lux. As the featural measuring elements of plants, the plant height, number of leaves, leaf length, leaf width, number of new leaves, and the amount of chlorophyll were measured. A data analysis was performed by Duncan's multiple range test with SAS programs. The result of the experiment is the following; 1. In the case of Polypodium vulgare L, it was grown and developed smoothly from 500lux to 2,000lux of fluorescent light, but under 100lux, it was withered away, or the leaves were fallen. Considering number of leaves, plant figure, interior photosynthesis rate, and photo of stoma, the growth was the best under 1,000lux. 2. In the case of Rumohra aristata (RORST) CHING, the withering phenomenon was not appeared, and the growth was possible under 100lux. Generally, the smooth growth was under the higher luminosity. In case of 2,000lux, the color of leaves was changed to the yellow, or the leaves were fallen, therefore, the freshness of the plants and plant figure were decreased. The proper luminosity was 1,000lux, and the statistical significance was not existed, and also a lot of chlorophy was under the lower luminosity, and the color of leaves was highlighted to the dark green. 3. In the case of Polystichum lepidocaulon(HOOKER) J. SMITH, the withering phenomenon was not appeared, and the growth was possible under 100lux. The growth was performed smoothly from 500lux, but, in the case of 2,000lux of maximum luminosity, the leaves was fallen, or the plant figure was dispersed. The order of good growth and development was 1,000lux, 500lux, and 2,000lux.
