초록
고소득 작물인 인삼의 생산비 절감 및 고품질화를 위한 새로운 재배법을 확립하기 위하여 Allelopathic 식물이 함유하고 있는 제초활성물질 탐색 동정한 결과는 다음과 같다. 12종류의 표준품을 이용하여 호밀과 귀리의 추출물에 대한 Allelopathy 물질을 분석한 결과, 두 추출물간에 함유하는 물질의 차이를 보였으나 호밀에서는 benzoic acids계열인 salicylic acid(8.34mg/g), 귀리에서는 flavonone glycosides계열인 naringin(7.50mg/g)이 가장 많이 함유되어 있음을 알 수 있었으며, 동정된 표준품을 이용하여
This study was conducted to identify allelopathic compounds in rye and oat straw extracts by HPLC analysis. These extracts were analyzed with 12 standard chemicals including salicylic acid. 11 chemicals in rye extract except for naringin and in oat extract except for catechin were identified. Salicylic acid(8.34mg/g) in rye straw extracts and naringin(7.50mg/g) in oat straw extracts among these standard chemicals were identified as the largest amount substance. The germination of Chenopodium ablum seeds was significantly inhibited by these chemicals at
