Abstract

This Study was Conducted in 3 glasshouse to examine the Possibility for cultivation of plug seedlings using four growing media containing recycled PET-bottle-particles (PBT) as a medium component. Plug seedlings of 'Seokwang' tomato were grown in media containing $100\%$ PBT, $100\%$ peatmoss, or $50\%$ $PBT+50\%$ peatmoss. A commercial plug medium (Tosilee) was used as the control. All seeds were sown in 128 cell plug trays on July 12, 2004. Seedling growth was measured at 30 days after sowing. Percent seed germination was greater than 95% in all treatments. Plant height, shoot fresh and dry weights, leaf area, and hypocotyl length were the greatest in the control treatment. Root length and weight were the greatest in the $100\%$ PBT treatment, which had a medium pH of 7.3. Leaf area and shoot dry weight were greater in the $50\%$ $PBT+50\%$ peatmoss treatment, than in the $100\%$ PBT treatment, while they were the smallest in the $100\%$ peatmoss treatment. No toxicity symptoms caused by the use or PBT had been observed in any treatment. The results suggest a possibility of recycled PBT, a valuable reusable resource, to be used as a component for medium amendments in horticultural transplant production.

본 연구는 재활용 PET-Bottle-Particles(PBT)가 함유된 4가지 생육배지를 이용하여 플러그묘 재배의 가능성을 실험하기 위해 유리온실에서 수행되었다. 토마토 '서광'의 플러그묘를 PBT $100\%$, peat moss $100\%$, 그리고 PBT $50\%+peat\;moss\;50\%$가 함유된 배지 및 상업적으로 이용되는 배지(토실이)를 대조구로 이용하여 육묘하였다. 128공 플러그 트레이에서 2004년 7월 12일에 파종하여 플러그묘의 생육은 파종 후 30일째 측정하였다. 모든 처리에서 $95\%$ 이상 발아하였다. 초장, 지상부 생체중과 건물중, 엽면적, 그리고 하배축 길이는 대조구에서 가장 컸다. 뿌리 길이와 무게는 PBT $100\%$처리에서 가장 컸으며, 이 배지의 pH는 7.3이었다. PBT $50\%+peat\;moss\;50\%$처리에서 엽면적과, 지상부 건물중이 PBT $100\%$ 처리에서 보다 컸으며, peat moss $100\%$처리에서 가장 작았다. PBT를 사용함으로 인한 독성증상은 관찰되지 않았다. 이 결과는 원예 묘종 생산에 있어 배지의 물리성 개선을 위한 구성요소로써 재활용 가능한 PBT의 이용 가능성을 제시해 준다.
