Abstract
In order to examine the factors affecting herbicidal injury of pepper, crop injury and growth response of 2 red pepper cultivars and 2 sweet pepper cultivars to napropamide and pendimethalin were evaluated under defferent conditions of soil texture, organic matter, soil temperature and seeding depth in the greenhouse. Growth response of 4 pepper cultivars was also examined by roos dipping to napropamide and pendimethalin. More inhibition of top leaf growth by root dipping to napropamide was occurred in red pepper cultivars than in sweet pepper cultivars. However, sweet pepper cultivars showed more severe inhibition of top leaf growth by root dipping to pendimethalin compared to red pepper cultivars. Crop injury due to napropamide and pendimethalin was more severe in sandy soil than in loam soil and this trend was more remarkably shown in sweet pepper cultivars. Crop injury due to napropamide and pendimethalin was reduced with the increase in organic matter especially in cv. Walgeykwan and cv. Orient al Pimento. As seeding depth of pepper cultivars became deeper, crop injury due to napropamide and pendimethalin was reduced in cv. Walgyekwan and cv. Oriental Pimento.
토양처리(土壤處理) 제초제(除草劑)인 Napropamide와 Pendimethalin을 고추재배(栽培)에 사용(使用)할 때 약해(藥害) 발생요인(發生要因)을 구명(究明)하여 약해(藥害)를 감소(減少)시키는데 필요(必要)한 기초자료(基礎資料)를 조사(調査)하고자 근부침지(根部浸漬)에 따른 고추 품종간(品種間) 생장반응(生長反應)과 토성(土性), 유기물(有機物) 함량(含量), 토양온도(土壤溫度) 및 파종심도(播種深度)에 따른 고추 품종간(品種間) 약해정도(藥害程度)를 비교(比較) 검토(檢討)하였다. 1. Napropamide는 근부침지(根部浸漬)에서 월계관 피만과 오리엔탈 피만의 최상위엽(最上位葉) 생장(生長)이 크게 억제(抑制)되지 않았다. 2. Pendimethalin은 근부침지(根部浸漬)에서 최상위엽(最上位葉) 억제(抑制)가 월계관 피만과 오리엔탈 피만에서 현저히 심했다. 3. Napropamide와 Pendimethalin의 약해(藥害)는 사토(砂土)에서 심하게 나타났으며 특히 피만계통(系統) 품종(品種)에서 더욱 심하였고 양통(壤土)에서 약해(藥害)는 적었다. 4. 유기물(有機物) 함량(含量)이 높을수록 Napropamide와 Pendimethalin의 약해(藥害)는 적은 경향(傾向)이었으며 월계관 피만과 오리엔탈 피만에서는 그 경향(傾向)이 현저하였다. 5 파종심도(播種深度)가 깊으면 Napropamide와 Pendimethalin의 약해(藥害)는 다소(多少) 적은 경향(傾向)이었으며 월계관 피만과 오리엔탈 피만의 고농도(高濃度)에서 그 경향(傾向)은 더욱 뚜렷하였다.
