초록

Echinacea 청정대량생산을 위해 재배환경조절이 강한 수경재배 시스템에서 Echinacea 뿌리와 잎 생산에 적합한 수경재배 시스템을 선발하고자 실험을 수행하였다. 실험에 사용한 공시작물은 E. angustifolia DC. 와 E. purpurea (L.) Moerch이며 NFT, modified NFT, DFT, aeroponics, Ebb & Flow등 5가지 시스템을 사용하여 150일간 실험하였다. 120일 수경재배한 두 종 모두 광합성 및 증산률은 Ebb & Flow 시스템에서 유의적으로 낮은 수준을 보였다. 정식 후 150일 째 지상부 생체중과 건물중은 E. angustifi이za의 경우 분무경과 DFT에서 높았고, E. purpurea는 분무경과 NFT에서 유의성 있게 높았다. 지하부의 생체중 및 건물중은 E. angustifolia와 E. purpurea는 분무경에서 가장 높았고 다음으로 M-NFT에서 높았다 두 종 모두 뿌리의 길이는 두 종 모두 NFT 및 Ebb & Flow 시스템에서 높았고 분얼수는 E. purpurea가 분무경에서 유의적으로 높았다. 따라서 Echinacea의 바이오매스 확보를 위한 수경재배 방식으로 광합성과 지상와 지하부 생육량이 E. angustifolia 와 E. purpurea 모두 높았던 분무경 시스템을 선발하였다.

This experiment was conducted to select optimum hydroponic systems for clean and mass production for shoot and root of Echinacea. E. purpurea and E. angustifolia. were grown at 5 different kinds of hydroponic systems; NFT, modified NFT, DFT, aeroponics, and Ebb & Flow for 150 days. The lowest photosynthetic rate and transpiration rate were in Ebb & Flow system in E. purpurea and E. angustifolia at 120 days after transplanting. The shoot fresh and dry weight were high in aeroponic and DFT system of E. angustifolia and in aeroponic and NFT system of E. purpurea at 150 days after transplanting. The root fresh and dry weight of both species were the highest in aeroponic system and next to modified NFT system. They were increased in NFT and Ebb & Flow system for the root length and in aeroponic system for the number of tillering. The results demonstrate that aeroponic system was the most effective for enhancement shoot and root biomass of Echinacea spp. in hydroponics.
