초록
천연물기원 신농약 개발을 위한 기초 단계로서 국내에 자생하고 있는 31과 59종의 식물체를 대상으로 생물활성을 평가하여 생리활성물질 함유 식물자원을 탐색한 결과는 다음과 같다. 1. 벼멸구 살충성분 함유 식물자원 탐색결과 21과 38종 식물체중 피마자잎의 조추출물은 1%(w/v) 농도수준에서 100%의 살충력을 보였으며, 고삼의 잎, 줄기, 뿌리와 상치, 할미꽃은 각각 82%, 84%, 80%, 75%의 벼멸구 살충효과를 나타냈다. 2. 벼흰잎마름병에 대해 활성을 나타낸 식물은 사철쑥을 비롯한 8종이었으나, 저지원효과는 0
For the selection of plants contained pesticidal active conpounds, 31 families 59 species of native plants were collected and biological activites of their crude extracts against brown planthopper (Nilaparvata lugens), Xanthomonas oryzae pv. oryzae and allelopathy were examined. Among the screened plants, the crude extracts from the leaves of Ricinus communis and Sophora angustifolia showed 100% and 82% of mortality on brown planthopper at the concentration of 1% (w/v) respectively. Mixed crude extracts of Sophora angustifolia root and Melia azedarach seed exhibited 128
