초록
'Casablanca'와 'Marco Polo' 품종의 구근 저장중 발생하는 부패병을 방제하기 위해 azoxystrobin, benomyl+thiram 및 prochloraz와 길항세균배양액 등을 처리하여 적정 약제 및 농도를 구명하고, 약제처리된 구근의 생육상 및 절화의 품질을 조사하여 약해의 유무를 판별하고자 수행하였다. 백합구근이 부패병 발생은 azoxystrobin과 prochloraz가 억제 효과가 있으며, Benomyl+thiram는 국내산 구근의 부패병 발병 억제 효과가 없는 것으로 조사되었다. 생리적으로 백합구근의 견고성을 증가시키기 위해 처리한 calcium chloride 혼용처리는 부패병을 증가시켰다. 길항세균 배양액을 1/5로 희석하여 처리하였을 때, 부패병이 발생을 효과적으로 억제하였다. 재배중 'Casablanca' 품종은 benomyl+thiram 처리구에서, 'Marco Polo' 품종은 benomyl+thiram와 calcium 혼용 처리구에서 맹아 억제가 심하였다. 구근의 저장전 약제처리는 백합의 영양생장 과정에서 생육상과 꽃의 품질에는 영향을 주지 않으며, calcium과 benomyl+thiram 처리구에서 잎과 꽃의 길이가 다른 처리구에 비해 작으나 유의차는 없었다.
This study was conducted to find out the proper chemicals and doses for controlling the bulb disease of Lilium Oriental hybrids 'Capablanca' and 'Marco Polo' cultivars during storage, and to ascertain any disadvantage of the treatment on shoot growth and flower development. Bulbs of 'Casablanca' and 'Marco Polo' cultivars were dipped in some fungicide solutions, including azoxystrobin, benomyl+thiram, and prochloraz, and culture broth of antagonistic bacteria for one hour. The rot was apparently inhibited by azoxystrobin and prochloraz solution dippings and it was not by benomyl+thiram in bulbs produced domestically. To improve physiological integrity, calcium chloride was treated. However, this treatment had no positive effects on bulb rot of lily. When bulbs were dipped in one-fifth of diluted broth. But the bulb rot was inhibited effectively as compared with untreated during storage. Benomyl+thiram and that with calcium inhibited the sprouting in 'Casablanca' and 'Marco Polo' cultivars during cultivation. Calcium and benomyl+thiram treatments decreased growth of leaf and flower but with no statistically significant difference. Other fungicidal materials treated to bulbs showed no effect on vegetative growth and flower quality.
