Abstract

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.

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.
