초록

본 연구는 자생 덩굴식물인 마삭줄과 후추등의 실내 광도차에 따른 생육특성의 변화를 알아보고자 광도 처리 조합을 3처리구를 만들어 환경 조절 생육상에서 조사하였다. 사용된 광원은 형광등이고, 광 처리를 각각 100lux, 1,000lux, 2,500lux로 달리하여 5개월간 생육특성 변화를 조사하였다. 자생 마삭줄은 저광도인 100lux에서 처리 2개월 이후 생존율이 약 16.7%로 식물체 대부분이 고사하였고, 1,000lux와 2,500lux에서는 처리 5개월까지도 생존율이 83.3%로 높게 유지되었다. 실내광도가 높아짐에 따라 초장, 엽수, 분지수, 엽장 및 엽폭은 증가하는 경향을 보였고 고광도인 2,500lux에서 가장 우세한 생육 및 생장을 보였다. 자생 후추등은 저광도인 100lux에서는 처리 4개월 후 생존율이 50%로 생육이 불량하였으나 1,000lux와 2,500lux에서는 처리 5개월까지도 100%의 높은 생존율을 보였다. 1,000lux 조건에서 엽록소 함량이 증가되는 경향을 보였고, 엽장과 엽폭이 약간 넓어지는 경향은 보였다. 상록성 덩굴식물인 자생 마삭줄과 후추등을 실내 광조건을 달리하여 처리한 결과 두 식물 모두 1,000lux 이상의 광조건에서 생육이 양호하였고 특히 후추등의 경우 마삭줄에 비해 1,000lux의 낮은 광도에서도 생육이 양호하고 잎이 넓어지고 엽색도 짙은 녹색으로 유지되어 실내식물로서 활용성이 높을 것으로 판단되었으나 광도가 지나치게 낮아질 경우 생육이 저조한 것으로 나타나 내 음성이 높다고 할지라도 정상적인 생육을 위해서는 적당한 광조건이 필요함을 알 수 있었다.

This study was conducted to develop new indoor plants and to investigate the effects of light intensity on the growth of Trachelospermum asiaticum var. intermedium Nakai and Piper kauzura. Most of T. asiaticum var. intermedium Nakai under 100 lux light intensity were blighted in two months, whereas survival rate was 83.3% after five months under 1,000 lux and 2,500 lux. Plant height, number of leaf, leaf width and leaf length increased as light intensity increased. The plants maintained under 2,500 lux showed the greatest plant height and leaf number. Piper kadzura Ohwi was defoliated and blighted in four months under 100 lux light intensity, whereas survival rate was 100% after five months under 1,000 lux and 2,500 lux. But, 1,000 lux light intensity was more favorable chlorophyll contents, leaf length and leaf width than 2,500 lux light intensity. Slight increase of chlorophyll contents and leaf growth under 1,000 lux indicates that Piper kadzura Ohwi could be utilized highly as a indoor ornamental plant.
