Abstract
효모추출물 4 mg/mL를 고추유묘에 경엽 및 뿌리 관주처리 24시간 후에 salicylic acid(SA)함량을 ultra high performance liquid chromatography(UHPLC)분석방법으로 측정한 결과 yeast cell wall extract(YCWE)처리구에서 대조구의 SA처리구와 동일한 peak가 검출되어 SA가 생성 유도 되는 것으로 확인 되었다. SA는 YCWE를 경엽처리 48시간 후 20.29 <TEX>${\mu}g/g$</TEX>으로 가장 높게 나타났으며 관주처리보다 약 3.7배의 높은 SA검출함량을 보였으나 처리 후 72시간부터는 점차적으로 SA함량이 감소하는 양상을 보였다. Yeast cell wall extract (YCWE) was treated on leaves and roots of pepper seedlings at the dosage of 4 mg/mL and salicylic acid (SA) production in pepper was detected by ultra high performance liquid chromatography (UHPLC). The SA production in pepper stem was induced by YCWE. SA was produced at the highest level of 20.29 <TEX>${\mu}g/g$</TEX> after 48 hrs of foliar spray with YCWE, which is 3.7 times higher than that of root perfusion with YCWM. SA production was gradually reduced after 72 hrs of YCWE treatment.
