초록
대두(大豆) 탄저병(炭疽病)(C. truncatum)을 공시(供試)하여 In vitro에서 광(光), pH 및 영양원(營養源)과 In vivo에서 시비수준(施肥水準)(P, K 및 Ca)이 부착기형성(附着器形成)에 미치는 영향(影響)을 조사(調査)한 바는 다음과 같다. 1. 3시간(時間) 및 6시간(時間)이 지난후의 조사(調査)에 따르면 광처리(光處理)를 한 것이 암처리(暗處理)를 한 것보다 부착기형성률(附着器形成率)이 양호(良好)하였다. 그러나 시간이 진행(進行)됨에 따라서는 각처리(各處理)에서 부착기형성률(附着器形成率)이 높아졌다. 2. 부착기형성(附着器形成)에 적정 pH는
The results investigated of the effect of light, pH, and nutrients in vitro and the levels of fertilizer(P,K and Ca) in vivo in order to find out the effect of environmental factors in forming an appressorium of Colletotrichum truncatum were as follows; The ratio of appressorium formation promoted more in a light treatment than in a dark treatment according to investigation after three and six hours passed away. But after the period, the ratio of appressorium formation promoted highly in both treatments. Reasonable pH of appressorium formation was pH 6-pH 8. The ratio of appressorium formation was the most favorable at none nutrient level in every treatment of C-source and N-source, and suppressed in a high concentration of C-source and N-source. But according as the time passed away, the ratio of appressorium formation promoted in C-source and N-source. When their quantities were increased in P and K treatments, the ratio of appressorium formation was somewhat suppressed but it was highly suppressed in the gradual order of none fertilizer level < standard fertilizer level < doubled fertilizer level in Ca treatment according to investigation after the first three hours passed away. But after the period, the ratio of appressorium formation promoted highly regardless of the level of fertilizer.
