약용식물을 플러그 트레이를 이용하여 공정육묘를 한 연구결과는 거의 없는 실정이다. 세 종류 약용식물 묘의 생산을 위한 기준을 마련하기 위해 플러그셀 크기가 플러그묘의 생장에 미치는 영향을 구명하기 위하여 본 연구를 수행하였다. 상업용 상토가 들어있는 128, 200, 288구 플러그셀 트레이에 종자를 파종하였다. 세종류 약용식물은 플러그 셀 크기가 커질수록 생육이 우수하였다. 하나의 플러그 트레이에서 얻어진 총 바이오매스는 차조기와 산두근은 288구에서 가장 높았고, 참당귀는 200구에서 가장 높았다. 총 엽록소와 안토시아닌 함량을 제외한 차조기의 지상부와 지하부 생장은 128구에서 가장 우수하였다. 하지만 최대근장, 엽장, 엽폭, 엽면적, 절간장, 뿌리 생체중, 근군형성은 200구와 288구에서 유의한 차이가 없었다. 산두근은 최대근장, 경경, 엽폭, 엽면적, 지상부 생체중, 근군형성을 제외한 모든 생장에서 처리간에 유의한 차이가 없었다. 그러나 최대근장, 경경, 엽폭, 엽면적, 지상부 생체중, 근군형성은 128구에서 가장 우수하였다. 엽록소 함량을 제외한 참당귀의 지상부와 지하부의 모든 생장이 128구에서 우수하였다. 경제적인 부분과 총 바이오매스를 고려했을 때 차조기와 산두근은 288구에서 육묘하는 것이 좋고, 참당귀는 200구에서 육묘하는 것을 권장한다.

There have not been many studies conducted on the seedling production, especially in plug trays, of traditional medicinal plant species. In an effort to establish guide lines for seedling production, this study investigated the effect of plug cell size on the growth and development of plug seedling of three medicinal plant species. Seeds were sown in either 128, 200, or 288-cell plug trays, containing a commercial medium. Growth and development of individual seedling was generally promoted with increasing size of a plug cell in all of the three species. The greatest biomass of the seedlings gained in a plug tray was obtained in the 288-cell trays in Perilla frutescens var. acuta Kudo and Sophora tonkinensis, and the 200-cell trays in Angelica gigas Nakai. Overall growth and development of the shoot and root of a single seedling of Perilla frutescens var. acuta Kudo, except total chlorophyll and anthocyanin contents, was the greatest in the 128-cell tray. However, length of the longest root, length, width and area of the leaf, internode length, root fresh weight, and root ball formation in the 200- and 288-cell trays were not significantly different each other. In Sophora tonkinensis, although length of the longest root, stem diameter, leaf width, leaf area, shoot fresh weight, and root ball formation were not significantly different among the treatments, length of the longest root and root ball formation of a single seedling were the greatest in the 128-cell tray. Overall shoot and root growth, except total chlorophyll content, of a single seedling of Angelica gigas Nakai was the greatest in the 128-cell tray. Based on the total biomass, it is concluded that 288-cell trays are recommended for production of plug seedlings of medicinal plant species P. frutescens var. acuta Kudo and S. tonkinensis. In A. gigas Nakai, it would be more economical to use the 200-cell trays than 128-cell trays due to total biomass.

문제 정의
Thus, more research is needed to establish a plug seedling production system for medicinal plants for the stable supply of medicinal plants. The objective of this study was to investigate the effect of cell size on the growth and development of plug seedlings to provide a guideline for production of plug seedlings to be supplied to growers of most commonly grown traditional medicinal plant species.
제안 방법
The experiment was carried out in 3 replicates per treatment in a completely randomized design. Data collected were analyzed for statistical significance with the SAS (Statistical Analysis System, V.
대상 데이터
The experiment was carried out in a glasshouse at Gyeongsang National University. The volume of each cell in 128, 200, and 288 plug cell trays were 23.
데이터처리
The experimental results were subjected to an analysis of variance (ANOVA) and Duncan’s multiple range tests at 5%.
후속연구
Improved standard of living of citizens and increased level of interest toward health caused increasing demand for medicinal plants. Thus, more research is needed to establish a plug seedling production system for medicinal plants for the stable supply of medicinal plants. The objective of this study was to investigate the effect of cell size on the growth and development of plug seedlings to provide a guideline for production of plug seedlings to be supplied to growers of most commonly grown traditional medicinal plant species.
