Abstract

Syzygium is a genus of Myrtaceae with 1,236 species. The functional traits of each species vary. The purpose of this study was to determine the variation in the functional traits of Syzygium leaves found in the lowlands and highlands. In this study, Syzygium leaves were collected from the Bogor Botanical Garden (lowland) for 27 species, while from the Cibodas Botanical Garden (highland) for 35 species. Ten parameters were measured, including leaf Fresh Weight (FW), leaf Dry Weight (DW), Leaf Area s(LA), Specific Leaf Area (SLA), Leaf Dry Matter Content (LDMC), Specific Leaf Weight (SLW), Chlorophyll Content (CC), Stomatal Density (SD), Stomatal Length (SL), and Stomatal Width (SW). Based on the results of the study, a diversity of functional traits in Syzygium species was observed in the lowlands and highlands. The results also indicated that the elevation influences variations in functional traits. Most of the leaf traits were found to be higher in the lowland species. Phenotypic plasticity of parameters was observed within the species found in both lowland and highland locations

Abstract

Cibodas Botanical Garden (CBG) maintains not only native plant species but also introduced plant species. Some of these have been naturalized from CBG to the adjacent Mt. Gede-Pangrango National Park (GPNP). One of the reported naturalized species is Bartlettina sordida. Understanding species traits will give information for the future management of B. sordida. This research investigates the distribution of B. sordida in the Cibodas hiking trail and studies leaf traits variation of this species along with an altitudinal change in the Cibodas hiking trail. Samples were collected along the Cibodas hiking trail from the entrance gate to the Cibeureum waterfall. At every survey location, we recorded B. sordida occurrences. In the sample plots we also collected leaf samples from detected B. sordida. The leaves were then fixated using the hands-free method to observed stomatal type, density, and size. The leaves were also treated for specific leaf area (SLA) measurements. Stomata size is significantly correlated along the altitudinal gradient. Stomata density is negatively correlated but not significant along the altitudinal gradient. Stomata size is positively correlated with SLA. These traits are related to water-efficient adapting to GPNP climate, which is very different from its natural habitat. The ability to adapt to altitudinal gradient helps B. sordida to dominate the Cibodas hiking trail.
