본 연구는 식물정유의 활용과 개발을 포함한 천연
물 제초제의 개발을 효과적으로 추진하기 위한 방안
으로서 식물정유 성분의 특성이 고려된 개선된 전식
물체(whole-plant) 검정법을 확립하기 위해 수행되
었다. 잡초 4초종을(피, 바랭이, 자귀풀, 어저귀) 이
용하는 전식물체 경엽살포 검정법은 검정 화합물 량이 충분할 경우, 전식물체 생장점 점적처리법은 검정
화합물이 미량일 때 추천할 수 있는 방법으로 판단되
었다. 각 식물정유 처리시 초기 처리농도는 2,500~
5,000μg mL-1 수준이 필요하였으며 계면활성제는
Tween 20 보다 NOP를 첨가하였을 경우에 보다 높
은 살초활성을 나타내었다. 식물정유와 같이 휘발성
이 있는 천연물의 활성을 평가하기 위해서는 약제를
처리한 후 과습 상태에 일정시간 두면 제초활성 발
현이 증진되었다. 또한 전식물체 생장점 점적처리법
은 경엽살포 검정법에 비해 약 1/100의 약제처리량
(부피), 약 1/200의 성분량(무게)에서도 살초효과의
검정이 가능하였다.
This study was carried out to establish an improved bioassay system, whole-plant
bioassay which is more effective in developing natural herbicides for foliar treatment such as
herbicidal essential oils. Two bioassay systems using four weed species (Echinochloa crus-galli,
Digitaria sanguinalis, Aeschynomene indica, and Abutilon theophrasti), spraying method and
spotting method, were established. Spraying method is applicable if the amount of test compounds
is enough, while spotting method is useful for the small amount of test compounds. The initial
application rate was desirable at 2,500~5,000 μg mL-1. Herbicidal activities were higher in the NOP
treatment when compared to the Tween 20 treatment. To efficiently evaluate volatile compounds
such as essential oils, if the compound-treated pots were incubated in dew chamber for about 10hrs,
better results were obtained in the degree and stability of herbicidal responses. When the efficiency
of bioassay systems established in this study was compared, the spraying method was minimized
four times to the conventional method that has beed used for screening of synthetic compounds in
KRICT. On the other hand, in the spotting method, screening for development of a natural herbicides
was possible even in level of 1/100 test volume and 1/200 amounts of test compound compared
to the spraying method.| 번호 | 참고문헌 | 국회도서관 소장유무 |
