연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

  • 따라서 본 연구는 새로이 대두되고 있는 염류 스트레스의 원인과 대책을 강구하고자 인삼의 잎과 뿌리에서의 반응을 분석하는 생리적 접근방식을 사용하여, 포트시험을 통해 생육특성 및 엽록소 형광반응 분석을 수행하였고, 이를 인삼 재배지 생리장해 토양의 화학성 조사결과와 비교하여 인삼 재배지 적정 나트륨 이온 농도를 구명하고, 나아가 내염성 인삼 육종의 기초 자료를 제공하고자 수행하였다.

인삼이 타 작물에 비하여 토양 특성에 영향을 더 많이 받는 이유는 무엇인가? , 2004). 인삼은 다른 식물과 달리 반음지 호냉성 식물로서 생육 최적온도가 18 - 22℃로 고온을 싫어하고, 10℃ 이하에서 100일 이상 지속되어야만 인삼 뇌두의 휴면이 타파되며, 고광 조건을 선호하지 않아 70 - 80% 정도의 그늘을 필요로 할 뿐만 아니라 (RDA, 2009a), 보통 3-5년의 긴 생육기간 동안 동일한 장소에서 자라기 때문에 타 작물에 비하여 특히 토양 특성에 따른 영향을 더 많이 받는다 (Kang et al., 2007; Jin et al.
국내 2014년 인삼 재배면적은 어떠한가? 우리나라 인삼 재배면적은 1996년 8,940 ha 이후 재배면적이 지속적으로 증가하여, 2000년에는 12,445 ha, 2009년에는 19,702 ha에 이르렀다. 그러나 2009년 이후 신규재배면적이 감소되면서 2014년에는 14,652 ha까지 감소하였다 (MAFRA, 2015). 그 결과 초작지 부족으로 인해 화학비료를 다량 연용한 다비작물 재배지가 예정지로 선정되는가 하면, 청초만 기비로 사용하던 과거 재배방식과 달리 농후사료를 먹인 각종 가축분뇨를 다량 시용함에 따라 토양 염류집적 문제가 심각하게 대두되고 있다 (Yoo et al.
고려인삼은 어떤 식물인가? A. Meyer)은 산형목 두릅나무과 (Araliaceae) 인삼속 (Panax)에 속하는 다년생 식물로, 국내에서는 한반도 전역에서 자생하고 있다. 현재 제주도 및 도서지역을 제외한 지역에서 시설재배 되고 있으며, 세계적으로 중국의 동북 3성 및 러시아 연해주 지역 등 북위 34 - 48 o 사이의 동북아시아 지역에서 자생한다 (Woo et al.
