Abstract
Germination test, nutrient culture test and pot experiment were conducted to determine selectivity of naproanilide between rice plants and paddy weeds. Naproanilide more severely inhibited growth of Scirpus juncoides, Sagittaria pygmaea and Cyerus serotinus than that of rice plant and Echinochloa crus-galli at germination stage. Root growth was severely inhibited than that of shoot growth by naproanilide treatment. Naproanilide severely inhibited rice plant and Echinochloa crus-galli at 30 uM, Sagittaria pygmaea at 1 uM and Cyperus serotinus at 10 uM in nutrient culture test, Rice plant and Echinochloa crus-galli did not show the difference of tillers and dry weight, but Scirpus juncoides, Morzochoria vaginalis and Aneilema keisak were severely inhibited at 15g/a and Sagittaria pygmaea and Cyperus serotinus at 30g/a in pot trial.
Naproanilide의 선택성(選擇性) 작용기작(作用機作)을 구명(究明)하기 위한 기초자료(基礎資料)로서 이용하고자 발아실험(發芽實驗), 수경재배실험(水耕栽培實驗)과 폿트실험(實驗)을 수행하였다. 1. Naproanilide는 발아실험(發芽實驗)에서 벼나 강피에 비해 올챙고랭이, 올미, 너도방동사니의 생장(生長)을 더 심하게 억제(抑制)시켰으며 줄기보다는 뿌리의 생장억제정도(生長抑制程度)가 심하였다. 2. Naproanilide는 수경재배실험(水耕栽培實驗)에서
