본 연구는 실내에 식물을 보다 효율적으로 도입하고 자 수경재배 시 첨가매질(게르마늄, 맥반석)이 관엽식 물의 생장과 잎의 무기성분, 뿌리활력에 미치는 영향을 구명하기 위하여 수행되었다. 싱고니움(Syngonium podophyllum), 드라세나 산데리아나(Dracaena sanderiana), 스킨답서스(Epipremnum aureum) 및 아이비 (Hedera helix)를 식물재료로 사용하였으며 토양(혼합 된 상토: Sunshine Mix No. 2, USA), 수돗물, 수돗 물에 게르마늄(300g), 수돗물에 맥반석(300g)을 첨가하 여 정식하였다. 첨가매질에 따른 생육변화는 싱고니움 의 경우 수돗물만 처리한 구에서 가장 저조하였고 게 르마늄 첨가구에서 생육이 가장 좋았으며, 드라세나 산데리아나는 처리구에 따른 생장의 차이가 거의 없는 반면, 스킨답서스와 아이비의 생장도 게르마늄 첨가구 에서 가장 좋았다. 특히 뿌리의 생장에서 커다란 차이 를 보였는데 근장, 근수 및 근중이 게르마늄 첨가구에 서 가장 좋았다. 뿌리활력은 10일 간격으로 분석하였 는데 작물마다 처리구에 따라서 변화가 있었는데 싱고 니움의 경우 10일째는 3처리구 다 뿌리활력이 낮아졌 으나 차츰 좋아져 30일과 50일째에는 맥반석 첨가구 에서 가장 좋았다. 드라세나의 경우 10일째부터 40일 째까지 게르마늄 첨가구에서 가장 좋았으나 50일째부 터 뿌리활력이 나빠졌다. 그러나 60일 후에는 처리구 간 큰 차이가 없었다. 식물체 잎의 무기성분 분석 결 과, 게르마늄의 Ca과 Mg 함량이 맥반석 보다 높았지 만 잎의 무기성분 함량에는 영향을 미치지 않는 것으 로 나타났다. 이상의 결과에서 스킨답서스와 아이비는 배지재배보다 수경재배에서 생장이 좋았고, 수경재배 시 수돗물에 게르마늄을 첨가하였을 때 생육이 증가하 는 것으로 나타났다.


This research was conducted for the purpose of investigating the influence substrates addition such as germanium or Granite porphyry gravel have on the growth of foliage, on the inorganic compositions of leaves as well as on root activity, in order to discover effective means of introducing plants to the indoors. Syngonium podophyllum, Dracaena sanderiana, Epipremnum aureum and Hedera helix were used as study subjects to which soil (mixed top-soil: Sunshine Mix No. 2, USA), tap water, tap water with germanium (300g), tap water with Granite porphyry gravel (300g) were added respectively and formulated. Studies on growth variations according to substrates addition indicate that growth of Syngonium podophyllum was most sluggish under tap water only treatment. Plant growth was most active under geranium-gravel treatment. In the case of Dracaena sanderiana, treatment of substrates addition had no meaningful influence on plant growth. However, the growth of Epipremnum aureum and Hedera helix was also shown to be most active under geranium-gravel treatment. Geranium-gravel treatment was shown to be particularly beneficial for root length, number of roots and dry weight. Root activity was analyzed on ten day intervals and there was discernable difference in the root activity of all the plants according to the varying treatments. In the case of the Syngonium podophyllum, the root activity was sluggish in all three types of treatment on the 10th day but improved gradually. On the 30th to the 50th day of the experiment, the root activity was found to be best under the Granite porphyry gravel treatment. In the case of the Dracaena sanderiana, the root activity was most active under the geranium-gravel treatment from the 10th to the 40th day but deteriorated from the 50th day. However, there was no significant different in all three treatments from the 60th day onwards. Analysis of the inorganic components of the leaves indicates that, while Ca and Mg were higher in the geranium than in the Granite porphyry gravel, they do not directly influence the content of inorganic components in the leaves. The results indicate that Epipremnum aureum and Hedera helix grow better under hydro-culture than when grown in soil and growth under hydro-culture is shown to increase when germanium is added to tap water.
