Abstract
- This is a study on relationship between soil pH and flower color and growth of Hibiscus siriacusL, lookingfor the pH range to result the most ideal flower color. I anticipate this study result will lay a foundation of improvedbreeding plan of Hibiscus siriacusL. According to the result of investigation and analysis on bleeding peculiarities byeach soil pH, the numbers of leaves in Honghwarang and Younggwang reached the highest at pH 7: 188.73 and 135.87respectively. Increased pH resulted the increased number of leaves. According to the result of investigation and analysison color changes of four kinds of Hibiscus siriacusL. at various pH level, Honghwarang's L value gradually decreasedfrom 17.05 to 12.26 at pH increase while a value increased from 16.37 to 20.91.Key words -Hibiscus syriacus, Soil pH, Flower Color, Cultivar- 145 -
