Variation of leaf morphology of hibiscus rosa-sinensis l. under various light intensities at Universitas Indonesia campus area and Citayam, Depok

Abstract

Hibiscus rosa-sinensis L. is a plant that has been cultivated as an ornamental plant, especially in Indonesia. Universitas Indonesia, located in Depok, has ten variations of H. rosa-sinensis in size, shape, and color of flowers. The flower shape consists of three types, namely, single, double, and crested. In this study, it is reported the comparison of leaf morphology from several types of H. rosa-sinensis L. Twenty leaves from each variety were used for morphometric measurement, and light intensity data from each location of the plant variety was also collected. There are two locations, Universitas Indonesia (UI) Campus Area and Citayam. The results showed that two individuals Crested Peach plant in Citayam, which grown under different light intensity has significantly different in leaf surface area but no difference in stomata surface area. Big Single Red and Double Pink located in UI exposure by the same light intensity has the same leaf surface area and stomata surface area. Comparing Small Single Red Citayam and Small Single Red UI exposure by different light intensity has significantly different in leaf surface area and stomata surface area. Two Crested Peach in UI, exposured by the same light intensity, were significantly different in leaf surface area and has the same stomata surface area. This study showed that light intensity could influence the variation of leaf morphology of several Hibiscus rosa-sinensis L. flower types, but not all flower types.
