Abstract

The cultivation of ‘Angelica gigas’ seedlings requires a prolonged nursery period, which has been recognized as a major technical constraint for growers. To overcome this limitation, plug seedling production has been explored; however, its application has remained largely at the experimental level due to various practical challenges. In addition, some growers have expressed concerns that plug seedling cultivation may reduce the content of decursin, a key bioactive compound in ‘Angelica gigas’, thereby potentially compromising product quality. This study aimed to provide fundamental information for improving seedling production systems by evaluating growth characteristics and major bioactive compound contents of ‘Angelica gigas’ seedlings produced in plug trays of different cell sizes after transplanting. Treatments included conventionally produced seedlings as the control, and seedlings raised in 50-cell vegetable plug trays and large forestry trays as experimental groups, all with a nursery period of 80 days. Seedling growth increased with tray cell volume, and this trend was maintained after transplanting. Seedlings produced in larger cells exhibited significantly greater fresh and dry weights, with those grown in large forestry trays showing approximately 1.8-fold higher dry weight at harvest compared with conventionally produced seedlings. In contrast, the contents of major bioactive compounds decursin, decursin angelate, and nodakenin were not significantly influenced by the seedling production method. Overall, these results indicate that plug seedling cultivation is an effective strategy for reducing nursery duration and improving land-use efficiency in ‘Angelica gigas’ production. Moreover, the use of large-cell trays appears to be particularly advantageous for enhancing seedling quality and promoting subsequent growth after transplanting, without negatively affecting the accumulation of key bioactive compounds.

참당귀 묘의 재배는 오랜 육묘 기간이 소요되어 농가의 주요 애로 기술로 지적되고 있다. 이를 해소하기 위한 대안으로 플러그 묘 육성이 시도되었으나, 다양한 제약 요인으로 인해 연구 수준에 머무르고 있으며 실제 현장 적용은 이루어지지 않고 있다. 일부 농가에서는 플러그 묘 이용 시 참당귀의 주요 성분인 Decursin 함량이 감소하여 품질 저하가 발생한다는 문제를 제기하기도 하였다. 본 연구는 플러그 트레이 규격별로 육성한 참당귀 묘를 대상으로 정식 후 생육 특성과 주요 성분 함량을 분석하여 참당귀 묘 육성의 기초 자료로 활용하고자 수행되었다. 처리는 관행 방식으로 생산된 참당귀 묘를 대조구로 하고, 채소용 50공 플러그 셀트레이 및 임업용 트레이를 처리구로 설정하였으며, 육묘 기간은 선행연구결과에 따라 80일로 하였다. 묘의 생육은 트레이 규격이 클수록 양호하였으며, 정식 후에도 동일한 경향으로 셀 부피가 큰 트레이에서 생체중과 건물중이 무거웠다. 특히 셀 부피가 큰 임업용 대형 트레이에서 육성된 묘는 수학 시 관행묘에 비해 건물중이 약 1.8배 무거웠다. 주요 성분인 Decursin, Decursin angelate, Nodakenin 함량은 육묘 방식에 따른 유의한 차이를 보이지 않았다. 이상의 결과를 종합하면, 플러그묘 활용은 육묘기간을 단축과 토지 이용 효율 측면에서 유리하며, 특히 셀 부피가 큰 트레이를 이용할 경우 묘의 품질과 정식 후 생육에서 유리할 것으로 판단된다.
