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.

Abstract ▼ AI-Helper 아이콘AI-Helper

In vitro studies using detached inflorescences with peduncles were conducted to investigate flower abscission agents in North American ginseng (Panax quinquefolius L.). Of the nine compounds studied only three, ammonium thiosulphate (ATS), abscisic acid (ABA) and ethephon induced abscission. Anilazi...

제안 방법

  • The experiment was Set up as a randomized complete block design with four blocks and 1 inflorescence per treatment. All treatments were randomized within each block on a table that was continually lit with a Phillips Ceramalux high pressure sodium lamp (400Watts- lOOVblts) which provided an average of 190 umol s-1 m-1 PAR (photosynthetically active radiation) at the inflores­ cences.
  • The experiment was repeated on three other dates (June 28, July 17 and August 8) using the same ethephon treat­ments and two new compounds each time. Inflorescences for the second experiment were collected on June 28 and a-naphthalene acetic acid (NAA) and thidiazuron were investigated (Table 1).

대상 데이터

  • At the beginning of these experiments (June 26) the percent bloom in the garden was about 48%. The first experiment resulted in a cumulative abscission of 20.3% from the 1500 mg - L-1 ethephon spray and 9.5% from the dip (Expt. 6). As the inflorescences used in the dip treatment all died and dried up, the head diameter and peduncle diameter decreased significantly compared to the controls.

데이터처리

  • Data analyses were carried out using the general linear model procedure of the Statistical Analysis System pro­ gram package (SAS Institute Inc., Cary, N.C.) at a proba­bility level of 0.05.
