Summary:The study was conducted in a glasshouse to examine the possibility of producing paprika plug seedlings in a newly developed inert phenolic foam growing medium. Plug seedlings of 'Fascinato' paprika were grown in five media, Grodan rockwool (Grodan Co. Ltd., Denmark), UR rockwool (UR Co. Ltd., Korea), phenolic foam LC (Smithers Oasis Korea Co. Ltd., Korea), phenolic foam RC, and phenolic foam 3813-4 all in a pellet type. Seeds were germinated in a growth chamber ($25^{\circ}C$, 90% RH, dark) for 4-5 days and then seedlings were grown in a glasshouse with nutrient solution supplied by an overhead irrigation system. Seedling growths were measured 20 days after sowing. The medium pH was the highest in the Grodan rockwool, and medium EC was the highest in phenolic foam 3813-4, although no nutritional excess disorders were observed. Germination rates of paprika were higher than 90% in all the media. Plant height, stem diameter, T/R ratio, leaf area, and chlorophyll showed a similar to those in the rockwool medium. Number of leaves, length of the longest root and dry weights of shoot were not significantly different among treatments. Overall, phenolic foam LC and RC produced seedlings with a similar growth as the rockwool medium. The results obtained suggest that rockwool can be replaced with a new material such as phenolic foam in the commercial scale production of plug seedlings of 'Fascinato' paprika. 본 연구는 새롭게 개발된 무기물인 phenolic foam 배지를 이용한 파프리카 파종용 플러그묘의 생산 가능성을 알아보기 위해 유리온실에서 수행하였다. Grodan 암면, UR 암면, phenolic foam LC, phenolic foam RC, phenolic foam 3813-4의 5종류 펠릿형 배지에 파프리카 'Fascinato'를 파종하였다. 종자는 식물생장상($25^{\circ}C$, 상대습도 90%, 암상태)에서 4-5일 동안 발아시켰고, 발아가 시작된 후에는 유리온실로 옮겨 두상관수로 양액을 관주하였다. 파프리카의 생육은 파종 20일 후에 측정하였다. 배지의 pH를 측정한 결과 Grodan 암면이 가장 높았고, EC는 phenolic foam 3813-4가 가장 높았지만 식물의 독성 증상은 관찰되지 않았다. 모든 배지에서 90% 이상의 발아율을 보였다. 초장, 경경, T/R률, 엽면적, 엽록소 함량은 암면 배지와 비교하였을 때 생육이 유사한 것으로 나타났다. 엽수, 최대근장, 지상부의 건물중은 유의적인 차이가 없었다. 전체적으로 phenolic foam 배지인 LC와 RC는 암면배지와 비교하여 유사한 생육을 보였다. 본 실험결과 파프리카 'Fascinato'의 상업적 규모의 육묘를 위해 암면을 신개발 물질인 페놀릭 폼으로의 대체 가능성을 확인하였다.
