Abstract

This is a study on relationship between soil pH and flower color and growth of Hibiscus siriacus L, looking for the pH range to result the most ideal flower color. I anticipate this study result will lay a foundation of improved breeding plan of Hibiscus siriacus L. According to the result of investigation and analysis on bleeding peculiarities by each soil pH, the numbers of leaves in Honghwarang and Younggwang reached the highest at pH 7: 188.73 and 135.87 respectively. Increased pH resulted the increased number of leaves. According to the result of investigation and analysis on color changes of four kinds of Hibiscus siriacus L. at various pH level, Honghwarang's L value gradually decreased from 17.05 to 12.26 at pH increase while a value increased from 16.37 to 20.91.

본 연구는 나라꽃 무궁화의 아름다움을 나타내는 화색에 미치는 요인 중 토양산도와 무궁화의 화색특성과 생장과의 관계를 조사 연구함으로써 가장 이상적인 색깔을 갖추는 pH 범위를 파악하여 무궁화 화색육종 계획의 기초를 마련하고자 하였다. 토양산도별 생육특성을 조사하고 분석한 결과 홍화랑과 영광 품종은 pH 7에서 엽수가 183.73개와 135.87개로 가장 높게 나타났으며 pH가 증가함에 따라 증가하였다. 토양산도별 4품종의 화색변화를 조사하고 분석한 결과 홍화랑 품종은 pH가 높아짐에 따라 L값은 $17.05{\sim}12.26$로 점점 낮아졌으며 a값은 $16.37{\sim}20.91$로 점점 높게 나타났다.
