EFFECT OF SOIL pH ON THE ANTHOCYANIN LEVEL OF HORTENSIA (<i>Hydrangea macrophylla</i>)
Abstract
Anthocyanin is a natural pigment that can express red, blue, and purple color. It can be accumulated in leaves, thorn, tuber, fruit, flower, and seed. Hortensia (Hydrangea macrophylla) known as ‘Panca Warna’, is a plant that can express different sepal colour due to environmental factor such as soil pH. The objective of this study was to determine the effect of three different soil pH on the level of anthocyanin pigment in the sepal of Hortensia. This research was a descriptive quantitative which used randomized block design with nine replications. Seven kind of anthocyanin was measured using differential pH spectroscopy method and analyzed using One-Way ANOVA. The result revealed that the three different soil pH did not affect the anthocyanin level among the measured samples.
