Abstract

This studies were performed to determine the effects of indoor relative humidity conditions on the growth of Arachniodes aristata and Pyrrosia lingua in native fern and investigate an applicable possibility of indoor plants. The response of Arachniodes aristata and Pyrrosia lingua was evaluated in growth chamber (KG-8407-87) to 3 relative humidity and 3 soils. Relative humidity was applied to 25%, 50%, 90%; soils were prepared based on soil mixture(SM), top field soil(TF), masa soil(MS). Results of experiments are as follows ; 1. Under a low humidity condition, such as 25%, Water contents, chlorophyll content, ornamental value of Arachniodes aristata and Pyrrosia lingua decreased much more a 50-90%. 2. The growth of Arachniodes aristata were best in pots under a soil mixture(SM) but Pyrrosia lingua were field top soil(FT) under 25%. It seemed that Pyrrosia lingua due to tolerance of desiccation more than Arachniodes aristata. Though these studies, coefficient of relative humidity and soil was plays an important role in Arachniodes aristata and Pyrrosia lingua growth in indoor environments.

자생 양치식물중 실내식물로서 개발가치가 높은 가는쇠고사리(Arachniodes aristata )와 석위(Pyrrosia lingua)의 실내 습도조건에 따른 생육 반응을 살펴보고자 수행하였으며, 그 결과는 다음과 같다. 1. 가는고사리와 석위는 상대습도 50%, 90% 보다 25%와 같은 저습도시 식물체내수분함량, 엽록소함량, 관상가치가 저하되었다. 2. 상대습도에 대한 용토별 생육에 있어 고습도인 90%일시 용토별 생육에는 큰 차이가 나타나지 않았으나, 중습도인 50%일 경우 일반 토양이 가장 좋은 것으로 나타났다. 저습도인 25%의 경우 가는쇠고사리는 인공배합토에서, 석위는 일반토양에서 생육이 좋은 것으로 나타났다.
