Abstract

Effects of butachlor [N-(butoxymethyl)-2-chloro-2', 6'-diethyl acetanilide] and 1,8-naphthalic anhydride (NA) on post-germination growth, mesocotyl and root anatomy and root-cell membrane permeability of rice (Orvza saliva L.) were investigated. Lengths of mesocotyl and radicle were markedly decreased as the application rates of butachlor increased from 0.1 to 100 ppmW and NA from 1 to 100 ppmW, but there was no effect on coleoptile elongation. Application of butachlor-NA resulted in increase in coleoptile elongation, but decrease in mesocotyl elongation. Partial breakdown of cortical cells in root and mesocotyl was caused by either trutachlor or NA treatments, resulting in increase in intercellular air space. Further increase in the intercellular air space of root and mesocotyl was obtained when butachlor was applied in combination with NA. Increase in root-cell membrane permeability occurred when either butachlor or NA was applied. However, butachlor-NA treatments resulted in reduction in the permeability.

벼의 발아후(發芽後) 생육(生育), 중경(中徑)과 근(根) 세포형태(細胞形態) 및 근(根) 세포막(細胞膜) 투과성(透過性)에 대한 butachlor와 1, 8 - naphthalic anhydride(NA)의 상호작용력(相互作用力)을 검토(檢討)하였다. Butachlor와 NA의 단일처리(單一處理)는 독도(獨度)의 증가(增加)와 함께 벼의 중경(中莖) 및 유근(幼根) 신장(伸長)을 현저히 억제(抑制)시키지만 엽초에 대해서는 영향(影響)을 미치지 않았다. Butachlor + NA 처리(處理)로 엽초 신장(伸長)을 증대(增大)되었지만 중경(中莖) 신장(伸長)은 감소(減少)되었다. Butachlor를 단일처리(單一處理)하면 중경(中莖) 근(根) 세포(細胞)의 피층세포(皮層細胞)가 부분적(部分的)으로 파괴된 세포간공극(細胞間空隙)이 형성(形成)되지만, NA를 동시(同時)에 처리(處理)하면 피층세포(皮層細胞)가 파괴된 세포간공극(細胞間空隙)은 더욱 확대(廓大)되었다. 벼의 근(根) 세포막(細胞膜) 투과성(透過性)은 butachlor와 NA의 처리농도(處理濃度) 증가(增加)로 확대(擴大)되지만, butachlor + NA의 처리(處理)로 감소(減少)되는 경향이었다.
