Inhibition of Floral Induction and Variation of Yield in Angelica gigas Nagai
참당귀의 화성억제와 수량변화
Abstract
Since the inhibition of floral induction was considered to be an important subject to get high yield of Angelica gigas, the effects of low temperature, daylengh and shading were investigated in this study. The yield of A. gigas root grown by inhibition of floral induction was compared with the yield obtained by traditional cultivation method. When the seedings were exposed to the natural low air temperature condition until late of November, the plants which had 6 to 8 leaves showed vernalizing effect, and when the low temperature treatment was prolonged until mid of January, 4 to 5 leaf plants showed vernalizing effect. But 2 to 3 leaf plants did not show vernalizing effect regardless of the length of chilling treatment. The effectiveness of exposure to low temperature was markedly dependent upon the age of plants. In the artificial low temperature treatment the range of temperature varied with plant age. Vernalizing effect at 1,5 and 9
참당귀(Angelica gigas Nakai)의 재배에서 크게 문제가 되는 화성억제를 위해 온도, 일장 및 광도가 화아분화와 추대에 미치는 영향을 조사했으며, 관행재배와 화성을 추제시켜 재배생산된 근의 수량을 조사하여 연근별로 비교하였다. 본 시험에서 얻어진 결과를 요약하면 다음과 같다. 1. 자연온도처리(대조구)의 경우 11월 20일 처리구의 본엽 6~8매부터 화아분화 및 추대가 시작되어 처리기간이 길어질수록 추대율이 증가하다가 익년 1월 11일 이후부터는 변화가 없었으며 본엽 2~3매 는 어떤 구에서도 추대가 전혀 없었다. 2. 인공온도처리의 경우 처리온도가 높아질수록 주온감응한계엽령이 증가하였다. 즉, 1
