초록

벼와 피의 속간(屬間) 선택성(選擇性)을 구명(究明)하기 위하여 제초제(除草除) cyhalofop-BE에 대(對)한 해부학적(解剖學的) 검경(檢鏡)을 통해 생장점(生長點)에 미친 영향(影響)을 조사(調査)한 결과(結果)는 다음과 같다. Cyhalofop-butyl ester 180ppm을 벼와 피에 처리시(處理時) 생장점(生長點)의 분제조직(分製組織) 저해(沮害) 양상(樣相)은 매우 유사(類似)하나 벼는 아주 경미(輕微)한 저해(沮害)를 보인 반면 피는 세포(細胞)의 분제(分製)이 억제(柳制)되고 배열(配列)이 불규칙(不規則)해지며 크게 위축(萎縮)되는 현상(現狀)을 보였다.

Basis for differential response of rice and E. crus-galli to cyhalofop-butyl ester (R-butyl 2-(4-(4-cyano-2-fluoro-phenoxy)phenoxy)propionate) was anatomically compared. Cell division in the growing point of E. crus-galli was severely inhibited by the herbicide, leading to malformation and irregular arrangement of cells. The inhibitory symptom of rice by cyhalofop-butyl ester appeared to be very similiar to that of E. crus-galli although its injury was negligible in rice when applied at the rate of 180ppm.
