Objective of this research was to investigate the effect of irrigation concentration on the growth and fruit quality of sweet pepper(Capsicum annuum L.) in fertigation. The sweet pepper was grown for 210 days with irrigation concentration of EC 0.5, 1.0, 1.5, 2.0, and 3.0 dSㆍm-1 in fertigation nutrient solution developed by European Vegetable R & D Center, Belgium. The net CO2 assimilation and transpiration rate were the highest in the treatment of 2.0 dSㆍm-1 . The pH in the soil was range of 5.63 ～6.03, the EC increased as the irrigation concentration was getting higher. The SPAD value also increased as the irrigation concentration was getting higher, N, P, K, Mg except Ca were highest in the treatment of EC 2.0 dSㆍm-1 . The growth was good in the treatment of EC 2.0 dSㆍmm-1 . The fruit length, width, firmness, and pericarp thickness had no statistical differences among treatments, the fruit fresh weight and dry weight were good in the treatment of EC 2.0 dSㆍm-1 the yield was good in the treatment of EC 1.5 dSㆍm-1 and EC 2.0 dSㆍm-1 The sugar contents was the highest in the treatment of EC 2.0 dSㆍm-1 with 9.0˚Brix. In conclusion, the optimal irrigation concentration for sweet pepper fertigation was EC 2.0 dSㆍm-1 .

황금(黃芩)(Scutellaria baicalensis)의 엽조직(葉組織)을 배양(培養)하여 기내(器內) 종묘(種苗)를 대양증식(大量增殖)시키고 유기(誘起)된 Callus 내(內)의 약효성분(藥效成分)을 검정(檢定)하여 2차(次) 산물(産物)의 효율적(效率的)인 이용(利用)을 도모하기 위하여 식물생장조절제(植物生長調節劑)가 캘러스유기 및 기관분화에 미치는 영향을 조사(調査)하였다. 엽(葉)으로부터 캘러스 유기(誘起)는 NAA 0.5mg / l 의 단독처리(單獨處理)에서 양호(良好)했으며, 혼합처리(混合處理)에서는 NAA 0.5mg / l 와 zeatin 0.5mg /l 의 처리구(處理區)에서 양호(良好)하였다. 캘러스로부터 식물체(植物體) 재분화(再分化)를 위해서는 BAP 1.0mg / l + NAA 0.5mg / l 와 zeatin 1.0mg / l + NAA 0.5, 1.0mg / L 혼합처리구(混合處理區)에서 가장 효과적(效果的)이었다. 2차(次) 산물(産物)의 이용(利用)을 위해 캘러스를 TLC법(法)에 의해 성분분석(成分分析)한 결과(結果) baicalin의 존재(存在)를 확인하였다.
