The purpose of this study was to analyze the growth and functional differences between C. rotundus and G. littoralis according to different electrical conductivity (EC) conditions in reclaimed soil conditions. C. rotundus and G. littoralis seeds were sown in a tray and managed for seedlings stage fo...

향부자에 함유된 주요 성분은? | 가뭄에 강해 비옥하지 않은 사양토에서 잘 자라고 따뜻한 기후에서 생육이 좋다(Kim 등, 1997). 향부자의 주요 성분에는 β-sitosterol, cyperol, flavonoids, cyperene, ascorbic acid, sesquiterpenoids, polyphenols 등이 있는데(Sonwa와 Konig, 2001), 향부자의 뿌리는 염증 및 피부 발진에 사용되고(Pal과 Dutta, 2006), 자궁 억제작용, 진통작용 및 해열작용에 도움을 준다(Hwang 등, 2012). 갯방풍(Glehnia littoralis)은 산형과에 속하는 다년생 초본으로, 우리나라의 해안사구에서 자생하며, 한국에서는 해방풍이라 불리고(Seo와 Ryu, 1977) 중국에서는 북사삼, 해사삼 등으로 칭하고 있다(Zhu 등, 1989). | |
향부자란? | 향부자(Cyperus rotundus)는 사초과에 속하며 한국, 인도, 중국 및 일본 등지에서 자라는 약용식물이다(Dassanayake 와 Fosberg, 1985). 가뭄에 강해 비옥하지 않은 사양토에서 잘 자라고 따뜻한 기후에서 생육이 좋다(Kim 등, 1997). | |
원예용 상토 대비 간척지 토양의 EC처리 농도에 따른 향부자의 생장 차이는? | 식물은 EC농도에 따라, 대조구, 1, 2, 4, 8dS·m-1 조건으로 12주간 실험을 진행했고 추가로 간척지 토양에서의 EC 1dS·m-1 과 원예용 상토를 구분하여 생육을 비교했다. 향부자의 초장, 엽장 엽폭은 EC 1dS·m-1 에서 가장 높았다. 엽수, 화방 수, 인편 수는 EC 2dS·m-1 에서 가장 크고 EC 8dS·m-1 에서 가장 적었으며, SPAD는 EC 2와 4dS·m-1 에서 가장 높고 EC 8dS·m-1 에서 가장 낮았다. 지상부와 지하부의 생체중은 EC 2dS·m-1 까지 증가하다가 농도가 증가함에 따라 값이 감소했다. EC 1dS·m-1 조건에서 간척지토양과 원예용 상토에서 자란 작물의 생육을 비교했을 때 SPAD, 엽수, 화방 수, 인편 수, 지상부와 지하부의 생체중은 원예용 상토에서 더 높았다. |
