Abstract
현재 유기재배에서 잡초 방제를 위한 방법은 관행방법에 비해 효과적이지 못하다. 본 연구는 하늘타리의 잎, 줄기, 열매, 뿌리 추출물 중 어느 부위에서 제초 효과가 가장 높은지를 알아보기 위해서 각 부위별로 물, 열수 그리고 에탄올로 추출하였다. 또한 위의 추출방법 중 제초활성능력이 뛰어난 것을 hexane, chloroform, ethyl acetate, BuOH, $H_2O$로 용매분획하여 잠재적 제초 성분에 대한 특성을 조사하였다. 전반적으로 오이와 보리의 발아율, 초장 및 근장 억제는 추출방법 중 물 추출법이 가장 효과적이었고, 식물체 부위별로는 열매에서 가장 효과적이었다. Ethyl acetate, butanol, chloroform, hexane, water의 용매분획에서 오이와 보리의 발아율, 초장 및 근장 저해는 물 층에서 가장 좋았고 그 밖의 분획에서는 차이가 없었다. 5% 물 층 추출물 발아전 처리에 의해 바랭이와 까마중의 생장량은 80~100% 억제되었으나, 이 추출물에 의한 오이와 보리뿐만 아니라 잡초종(바랭이, 까마중 등) 경엽처리에 의한 생육저해 효과는 없었다. 본 연구결과로 볼 때 하늘타리 추출물을 친환경 또는 유기농 재배에 잡초방제를 위해 사용할 수 있을 것으로 본다. Currently, methods for controlling weeds in organically produced crops have not been as effective as conventional methods. This research was carried out to determine the herbicidal effects of leaf, stem, fruit, root extracts of Trichosanthes kirilowii. The extraction methods used were water, boiling water and ethanol. The characteristics of potential herbicidal components among extraction methods were investigated by using the following solvent fractions: hexane, chloroform, ethyl acetate, butanol, and water. Generally, water extracts provided the best on inhibition of germination rate, plant height, and root length in cucumber and barley. Specifically, extractions made from fruit parts of T. kirilowii provided the greatest inhibition effect on plant growth in cucumber and barely. Inhibition of germination rate, plant height, and root length in cucumber and barley in solvent fractions was the best in water fractions, but there were no significant differences among the other fractions. Digitaria siliaris and Solanum nigrum were controlled 80-100% by 5% extractions of water fraction. However, there were no herbicidal effects from foliar treatment in cucumber, barley, black nightshade, and henry crabgrass by 5% extractions of the water fraction. These results show that extractions of T. kirilowii can be used for controlling some weeds in organically produced crops.
