유채(Brassica napus L.) 종자의 발아와 초기생장을 억제하는 식물정유의 선발 = Selection of Essential Oils Inhibiting Germination and Initial Growth of Rapeseed (Brassica napus L.)

국문 초록 (Abstract)

본 연구는 19종의 식물정유가 유채종자의 발아 및 생장에 미치는 영향을 파악하기 위하여 수행되었다. 그 결과 식물정유를 100배 희석 처리 한 경우 anise, cinnamon, citronella, clove, geranium, lemongrass, mustard 및 pine oil 등의 8종은 유채의 발아를 완전히 저해하였으며, 초기생장의 저해효과도 큰 것으로 나타났다. 유채의 발아와 초기생장에 대한 저해율을 근거로 하여, 상기의 8개의 식물정유로부터 cinnamon, clove 및 geranium oil이 실용 가능성이 있는 bio-herbicide로서 선발되었다. 선발된 cinnamon, clove 및 geranium oil을 토양처리한 경우 90㎏ ai ha-1농도에서 유채의 출현율은 각각 7.1, 25.0, 3.6% 였으며, 초기생장율도 22.0, 9.9 및 11.0% 수준으로, 유채종자의 발아와 초기생장억제에 미치는 효과가 큰 것으로 나타났다.

다국어 초록 (Multilingual Abstract)

This study was conducted to investigate the phytotoxic effects of 19 essential oils on seed germination and initial growth of rapeseed (Brassica napus L.). We found that anise, cinnamon, citronella, clove, geranium, lemongrass, mustard and pine oils completely inhibited germination of rapeseed at 100× dilute solution. Based on the inhibition rates of rapeseed emergence and initial growth, three essential oils (cinnamon, clove, and geranium) were selected a potential bio-herbicides. Under pre-emergence applications of cinnamon, clove, and geranium oils at 90 ㎏ ai ha-1, rates of rapeseed emergence were 7.1, 25.0, and 3.6% and its initial growth were 22.0, 9.9 and 11.0%, respectively.
