Effects of Temperature, Light, $GA_3$ and Storage Method on Germination of Angelica gigas NAKAI

온도(溫度), 광(光), $GA_3$ 및 저장방법(貯藏方法)이 참당귀(當歸) 발아(發芽)에 미치는 영향(影響)

Theses studies were conducted to clarify the germinating characteristics of seed treated with different temperature, light, and ($Gibberellin(GA_3)$) to produce the homogeneous seedlings Angelicogigas NAKAI. The results obtained are summarized as follows: Rate and speed of germinating at $25^{\circ}C$ were higher than $15^{\circ}C$and $20^{\circ}C$ by 87.3% and 68.9% and also the required day for germination at 25°C was shortest by 14.1 days. Germination rate at the light condition was 90.7% and that at the dark was 65.7%. Germinating ability of seed stored at $4^{\circ}C$and $-10^{\circ}C$ for 165 days as dried states was 92.0% and 91.3%, while that at room temperature was 50.3%, but the longer storage of seed than 165 days decreased the ability. Gibberellin treatment by 10ppm to seed stored at $4^{\circ}C$ and by 6ppm to seed stored at $-10^{\circ}C$ increased the germination rate more by 20.9% and 31.7% than nontreated seed.

본(本) 시험(試驗)은 참당귀(當歸) 종자(種子)의 발아율(發芽率) 향상(向上)과 균일(均一)한 묘생산(苗生産)을 위한 기초자료(基礎資料)를 얻고자 온도(溫度), 광(光), $GA_3$처리(處理)와 저장방법(貯藏方法)이 발아(發芽)에 미치는 영향(影響)을 알아보고자 수행(遂行)한 시험결과(試驗結果)를 요약(要約)하면 다음과 같다. 1. 발아온도(發芽溫度)는 $25^{\circ}C$에서 발아율(發芽率) 87.3%와 발아세(發芽勢) 68.0%로 가장 높고, 평균발아(平均發芽) 일수(日數)도 14.1일(日)로 가장 짧았다. 2. 광조건(光條件)에서의 발아율(發芽率)은 90.7%, 암조건(暗條件)에서는 65.7%로 광조건(光條件)에서 발아(發芽)가 양호(良好)하였다. 3. 종자(種予)의 발아력(發芽力)은 채종후(採種後) 165일(日) 보관(保管)은 $4^{\circ}C$와 $-10^{\circ}C$건조(乾燥) 저장(貯藏)에서는 각각(各各) 92.0와 91.3%로 높았으며, 상온(常溫)에서는 80.3%, 그 이후(以後)에는 급격(急激)히 발아율(發芽率)이 떨어졌다. 4. $GA_3$처리(處理)에 따른 발아율(發芽率)은 $4^{\circ}C$저장(貯藏) 종자(種字)는 $GA_3$ 10ppm에서 49.9%로 무처리(無處理) 29.0%보다 20.9% 증가(增加)되었으며, $-10^{\circ}C$저장(貯藏) 종자(種子)는 6ppm에서 63.0%로 무처리(無處理) 31.3% 보다 31.7% 증가(增加)되었다.
