본 연구는 식물 정유인 clove oil과 pine oil에 의한 벼 엽록소 함량 감소, 잡초방제 효과 및 식물 정유에 포함된 주요 유기화합물의 성분을 확인하기 위해 실시되었다. 식물 정유 처리 24, 48, 96, 및 168시간 후의 벼 엽록소 함량은 clove oil 10배 희석액의 경우 무처리 대비 각각 59.9, 54.6, 27.1, 및 14.5%였으며, pine oil 10배 희석액은 각각 47.2, 23.5, 15.7, 및 10.9%로 나타났다. Clove oil과 pine oil 10배 희석액의 엽록소 함량 감소효과는 glufosinate ammonium 기준량 처리보다 더 큰 것으로 나타냈다. 식물 정유 희석액의 잡초방제 효과는 농도가 높아질 수록 증가하였는데, 그 정도는 잡초종의 종류에 따라 다른 것으로 나타났다. 화본과 잡초는 광엽 잡초에 비해 방제 효과가 높은 경향이었으며, 광엽 잡초 중 비름 및 가막사리에 대한 방제 효과는 깨풀, 털별꽃아재비 및 닭의장풀 보다 더 높은 경향이었다. 식물 정유 성분을 분석한 결과 clove oil의 주성분은 squiterpene에 속하는 caryophyllene (44.61%) 및 phenolpropanoids에 속하는 eugenol (38.93%) 이었으며, pine oil의 주성분은 monoterpene에 속하는 (+)-3-carene (38.53%), α-terpinolen (23.15%) 및 limonene (10.86%)이었다. This study was conducted to investigate the reduction of rice chlorophyll content and herbicidal effects of clove oil and pine oil, and to identify the components of major organic compounds contained in the plant essential oils. The chlorophyll content of rice after 24, 48, 96, and 168 hours of plant essential oil treatment was 59.9, 54.6, 27.1, and 14.5% in the case of 10 times dilution clove oil, and 47.2, 23.5, 15.7, and 10.9% in pine oil 10 times dilution, respectively. The chlorophyll reduction effect of 10 times dilution of clove oil and pine oil was greater than that of the recommended amount of glufosinate ammonium. As the concentration of the plant essential oil dilution increased, herbicidal effects increased, but the effect was different depending on the weed species. Herbicidal effects was higher in the glass weeds than in the broadleaf weeds, and the control effects on Amaranthus mangostanus and Bidens tripartita among the broadleaf weeds tended to be higher than those of Acalypha australis, Galinsoga ciliata, and Commelina communis. As a result of analyzing the components of essential plant oils, the main components of clove oil were caryophyllene (44.61%) belonging to squiterpene and eugenol (38.93%) belonging to phenolpropanoids, and the main components of pine oil were (+)-3-carene (38.53%), α-terpinolen (23.15%) and limonene (10.86%) belonging to monoterpene.
