KAJIAN MORFOLOGI KITOLOD (Hippobroma longiflora (L.) G. Don) DI KECAMATAN TAMPAN PEKANBARU

Abstract

Kitolod (Hippobroma longiflora (L.) G. Don) is a plant group of Campanulaceae. This plant is classified as a medicinal plant that is considered to have antioxidant properties. Secondary metabolite compounds are flavonoids, phenolics, chlorophyll, carotenoids and ascorbic acid which are contained in all organs of the kitolod plant. Kitolod includes weeds that are commonly found in open and damp places such as around waterways. Environmental conditions can cause differences in the morphology of kitolod plants. The purpose of this study was to determine the intraspecies diversity of Kitolod plants based on morphological characters in district Tampan of Pekanbaru city. This study used a sampling method by means of a survey and characterization was carried out at the sampling location and at the Botanical Laboratory, Department of Biology, FMIPA, Riau University which was carried out from March 2022 to May 2022. A total of 10 Kitolod individuals were scored based on their morphological characters and analyzed by clusters to determine grouping using NTSYS-pc 2.02. The results showed that the highest similarity coefficient was owned by HL1 and HL2 individuals with a value of 0.859. Dendrogram analysis showed clustering occurred at a coefficient of 45% dividing into 2 large groups in the form of group I consisting of 7 individuals and group II consisting of 3 individuals of Kitolod plants.
