본 연구는 후박나무 용기묘를 대상으로 전광, 35%, 55%, 75% 차광수준에 따른 생장 특성 및 생리적 반응을 알아보고자 실시하였다. 후박나무 묘목은 차광 시 상대적으로 지상부의 생장특성을 보여주는 지표들이 높은 경향을 보였으며, 전광에서는 뿌리와 관련된 지표인 뿌리건중비, 뿌리생장에서 유의적으로 높은 경향을 보였다. 또한, 전광에서의 낮은 광보상점과 높은 순양자수율은 이미 후박나무가 내음성을 가지고 있고, 광이 부족한 환경에 노출된 차광처리구들에서 암호흡량의 감소, PIABS 및 SFIABS의 증가로 광합성 기구의 활력을 효율적으로 증가시키는 것을 알 수 있다. 한편, 전광은 지상부 비율의 증가, 낮은 T/R율과 가장 높은 순광합성속도를 보여 광합성으로 합성되는 탄수화물이 지상부뿐만 아니라 지하부의 생장 역시 증가시킨 것을 알 수 있는 결과였다. 따라서 후박나무 용기묘는 전광조건에서 생장 및 생리적 특성이 가장 양호한 경향을 보였다.

The purpose of this study was to evaluate the growth characteristics and physiological responses of Machilus thunbergii container

seedlings under full sunlight, 35%, 55%, and 75% shading levels. In shade treatments, indices indicating aboveground growth characteristics tended to be relatively high, whereas in full sunlight, root-related indicators such as root weight ratio and root growth tended to be significantly higher. Furthermore, the low light compensation point and high apparent quantum yield in full sunlight indicate that M. thunbergii already has shade tolerance, and it can be seen that the vitality of the photosynthetic apparatus is efficiently increased by reducing dark respiration and increasing PIABS and SFIABS in shade treatments exposed to a light-sufficient environment. Meanwhile, the full sunlight treatment showed an increase in the aboveground part ratio, a low T/R ratio, and the highest net photosynthetic rate, denoting that carbohydrates synthesized by photosynthesis increased the growth of both the aboveground and underground parts. Overall, container seedlings of M. thunbergii represented the best growth and physiological characteristics under full sunlight treatment.
