초록
1976연, 1977년 및 1980연의 3개년간 진흥과 유신을 공시, 질소질보비구와 배비구로 나누어 6월 21일부터 9월 21일까지 생유 및 잎집무늬마름병의 발병조사를 실시한 결과, 1, 생육상황에 있어서는 진흥이 유신보다 초장이 길었으며 8월 1일 이후에는 질소시비수준에 관계없이
The percentage of lesion height vs. plant height was higher in Yushin than Jinheung within the same nitrogen level. The infection occurred at the same level of waterline and the symptoms developed with the same speed for two varieties, but the damage was greater in Yushin as the symptoms reached faster to the top due to the short length of the 1st and 2nd internodes from the top.
