초록

환경오염과 자원 고갈 문제가 심화됨에 따라 재생 가능하고 생분해가 가능한 바이오소재 개발이 지속 가능한 산업 발전의 핵심 과제로 대두되고 있다. 본 연구는 동아시아 지역에서 자생하는 꽝꽝나무(Ilex crenata Thunb.)를 대상으로, 발아 증진 및 순화재배 기술을 체계적으로 정립하여 대량 생산 체계를 구축하고 바이오소재로서의 산업적 활용 가능성을 평가하고자 하였다. 본 연구에서는 GA , KNO , NH NO , KH PO , PEG와같은 다양한 프라이밍 처리제를 이용하여 꽝꽝나무 종자의 발아 특성과 유묘 생육 특성을 분석하였다. 그 결과, KNO 50 mM 처리구는 발아율을99.0%까지 증가시키며 발아 과정을 가속화하는 데 효과적이었다. 그러나 유묘 생육 및 단위면적당 수확량에서는 NH NO 200 mM 처리구가가장 높은 증가를 보였으며, 이는 질소의 두 가지 형태(NH , NO )를 동시에 제공하여 질소 대사를 극대화한 결과로 판단된다. 유묘활력지수(SVI)또한 NH NO 200 mM 처리구에서 254.3±41.6으로 가장 높게 나타났으며, 이는 대량 생산과 바이오소재 원료로의 활용에 적합한 조건으로확인되었다. 본 연구는 발아 증진 기술 및 초기 생육 안정화를 통해 꽝꽝나무의 대량 재배 가능성을 제시하였으며, 지속 가능한 그린바이오소재 개발에 중요한 기초자료를 제공하였다. 향후 다양한 재배 조건과 종자 특성에 따른 최적화 연구가 추가적으로 필요할 것으로 판단된다

Abstract

As environmental pollution and resource depletion intensify, the development of renewable and biodegradable biomaterials has emerged as a key challenge for sustainable industrial development. This study focused on Ilex crenata Thunb., a plant native to East Asia, aiming to systematically establish germination enhancement and acclimatization techniques to build a mass production system and evaluate its potential as an industrial biomaterial. Various priming agents, such as GA , KNO , NH NO , KH PO , PEG, and PEG, were appliedto analyze the germination characteristics and seedling growth of Ilex crenata seeds. As a result, the KNO 50 mM treatment effectively increased the germination rate to 99.0% and accelerated the germination process. However, seedling growth and yield per unit areawere highest in the NH NO 200 mM treatment group, which was attributed to the provision of both ammonium (NH(NO ) forms of nitrogen, maximizing nitrogen metabolism. The seedling vigor index (SVI) was also highest at 254.3±41.6 in the NH NO4 +) and nitrate200 mM treatment, confirming it as the optimal condition for large-scale production and utilization as a biomaterial raw material. This study highlights the feasibility of large-scale cultivation of Ilex crenata through germination enhancement techniques and initial growth stabilization, providing essential foundational data for the development of sustainable green biomaterials. Further research is needed to optimize cultivation conditions and seed-specific characteristics.
