초록

Geraniol의 작물 생장촉진능을 평가하고자, 쌈배추, 양상추, 잎들깨, 쑥갓, 청경채를 대상으로 패트리디쉬에서 유근생장 시험을 한 결과 쌈배추, 양상추, 잎들깨에서 $0.5-10mg\;L^{-1}$ geraniol 처리시 유근생장이 30% 이상 촉진됨을 확인할 수 있었다. 또한, geraniol의 생장촉진능을 포트에서 재배되는 쌈배추를 대상으로 관주과 경엽처리를 통해 평가한 결과, $100mg\;L^{-1}$ 관주처리시 지상부 생장이 최대 190%까지 촉진됨을 확인할 수 있었다. 이러한 지상부 생장촉진은 엽수, 엽폭, 엽장 생장이 촉진되어 나타난 결과로 판단되었다. 다만, 경엽처리의 경우 $100mg\;L^{-1}$ 처리구에서만 유의적 수준의 생장촉진이 확인되었으나, 관주처리의 경우 $20mg\;L^{-1}$의 낮은 처리농도에서도 지상부 생장촉진이 확인되었다. 따라서, 작물 생장촉진을 위한 geraniol의 처리법은 경엽처리보다는 관주처리가 보다 적합한 것으로 판단되었다.

This study investigated the plant growth promoting activity of geraniol on Chinese cabbage (Brasscia campestris ssp. Pekinensis Rupr.), Pak Choi (Brassica rapa L.), Crown daisy (Chrysanthemum coronarium L.), Iceberg lettuce (Lactuca sativa L.) and Leaf perilla (Perilla frutescens Britt.). Geraniol at 0.5 to $10mg\;L^{-1}$ promoted radical growth of Chinese cabbage Pak Choi, Crown daisy, Iceberg lettuce and leaf perilla by >30%. In the pot experiments, geraniol treatment at $20mg\;L^{-1}$ by drenching increased up to 190% of the aerial part growth promotion. By comparison, foliar application showed 124% promoting activity only at $100mg\;L^{-1}$.
