초록

최근 농작물의 상황을 실시간이면서도 비파괴적으로 측정하는 시스템이 스마트팜 등의 분야에서 필수적인 요소로 주목받고 있다. 본 연구에서는 초분광 영상 기술을 통해 많은 개체 수의 청경채 유묘 내의 안토시아닌 함량을 비파괴적으로 동시에 측정하였다. 많은 유묘의 동시 측정을 위해서, 기존의 초분광 영상 시스템의 실험 구성을 수정하였다. 품종당 24개씩 총 96개의 유묘를 측정하였고, 한번의 초분광 데이터 획득시 12개의 유묘가 동시에 분석 가능했으며, 총 3분이 소요된다. 본 논문에서 제안한 초분광 영상 기술은 파괴적 화학 분석 방법과 비교 가능한 분석 시스템을 제공하는 것으로 나타났다. 또한 많은 수의 식물을 동시에 측정함으로써, 초분광 영상 기술이 초고속 피노타이핑 시스템에 적용될 수 있다는 가능성을 확인하였다.

Recently a system for nondestructive measurement of seedling plants in real time has been attracting attention as an essential element in fields such as the "smart farm". This study reports the simultaneous measurement of anthocyanin accumulations in leaf tissues in a large number of bok choy, using a hyperspectral imaging system. To measure many seedlings simultaneously, an existing hyperspectral imaging system is modified. In this paper, a total of 96 seedlings are measured: 24 each of 4 cultivars. Using the hyperspectral data-acquisition system, 12 seedlings can be analyzed simultaneously within 3 minutes. The hyperspectral imaging technology proposed in this paper is shown to provide an analytic system comparable to destructive chemical analysis. This hyperspectral imaging technology can be applied to a high-throughput plant-phenotyping system, owing to its capability of measuring a large number of specimens at the same time.
