아연광산 인근 토양중의 중금속 함량이 콩의 생육 및 중금속 흡수에 미치는 영향
최부술,김복진,박노권,박선도,이종팔 한국환경농학회 1996 한국환경농학회지 Vol.15 No.3
중금속으로 오염된 토양에 콩을 재배하였을 때 토양 중 중금속함량이 콩의 생육 및 중금속흡수에 미치는 영향을 요약하면 다음과 같다. 1. 중금속 오염지역의 콩 생육은 현저히 불량하였고, 토양 중 중금속함량도 월등히 많았다. 2. 중금속 오염지역내에 재배되고 있는 작물별 잎중의 Zn, Cu, Pb, Cd, As 등 중금속함량은 콩에서 가장 많았고 다음은 옥수수, 벼 순이었다. 3. 콩의 부위별 중금속함량은 Pb외에 줄기보다 잎에서 많았으며, 원소별로는 Zn > As > Cd > Cu > Pb 순이었다 4. 콩 생육과 토양 중 Zn, Cu, Pb, Cd, As함량과는 유의한 부의 상관이 인정되었다. 5. 토양 중 Zn, Cu, Pb, Cd, As함량과 콩잎의 Zn, Cd, As함량과 콩줄기의 Pb, Cd, As함량과는 고도의 유의성이 있는 것으로 보아 중금속 오염지에서는 식물체에 흡수 축적되는 것으로 생각되었다. When soybean was cultivated in the polluted soil with heavy metals, the content of these heavy metals affected. The results were summarized as follows. 1. The growth of soybean was remarkably poor and the content of heavy metals in polluted soil were higher than in unpolluted soil. 2. In leaves of all surveyed crops, the content of Zn, Cu, Pb, Cd and As was higher in soybean, followed by corn and rice. 3. Except for Pb, the content of heavy metals in the leaves of soybean was higher than in the stem of soybean, and the components of heavy metals in each part of soybean were shown in order of Zn > As > Cd > Cu > Pb. 4. The relationship between the content of Zn, Cu, Pb, Cd, As and the growth of soybean was negatively correlated, respectively. 5. A higher correlation seemed to exist among the content of Zn, Cu, Pb, Cd, As in soil, of Zn, Cu and As in soybean leaves, and of Pb, Cd and As in stems of soybean. The results indicated that heavy metals were absorbed and accumulated by plants grown in the polluted area.

The typhoon and flooding injury in rice were investigated both the region of downpour at the middle of August and the region of typhoon "Yanni" at the late of September, 1998 in Kyongbuk provincial of Korea. More than 10% of rice stem were buried by soil inundation, the heading was delayed and the high node tiller was brought out. Yield components were deteriorated and yield was reduced. As the clay in the muddy water was attached on grains of rice, the yield was greatly reduced by reason of low grain filling ratio and polished rice ratio. The injury of muddy water was less at yellow ripening stage than at early ripening stage. On the other hand, the muddy water injury was reduced by the fungicide "Benomyl" and "Daconil" treatments. The degree of lodging according to varieties and ripening stages was not made a great difference, while the lodging was mainly occurred in the early transplanting time. In a week after lodging, viviparous spikes were occurred in almost all varieties, the degree of viviparity was shown highly in order of early maturing, middle maturing and late maturing varieties in the field as well as in laboratory test. The viviperous spikes were greatly occurred in the lodging toward hill space within row than row space because the more grains were touched on the ground.
Penicillium corylophilum 에 의한 큰느타리버섯 (Pleurotus eryngii) 푸른곰팡이병의 발생
최부술,조우식,류영현,김승한,윤재탁 한국균학회 1999 韓國菌學會誌 Vol.27 No.6
Bluish green mold of Pleurotus eryngii caused by Penicillium was observed in Seungju on Feburary 4, 1999. The causal fungus was identified as Penicillium corylophilum based on its cultural and morphplogical characteristics. Conidiophores one-stage branched, terminating in a whorl of 2∼4 metulae. Metulae mostly 10∼18×2.5∼3.0 ㎛. Phialides flask-shaped, 9∼13×2.2∼2.8 ㎛. Conidia subglobose, 2.5∼3.2×2.5∼3.0 ㎛. Colonies on Czapek agar mostly attaining a diameter of 21 ㎜ within 7 days at 25℃. Colour blue-green soon becoming grey-green. Pathogenicity test by wound inoculation revealed that Penicillium corylophilum caused the same symptoms as observed in the field at 6∼7 days after inoculation.
