Abstract

Dendrobium and Phalaenopsis are genetic resources of orchids that are increasingly rare, so breeding efforts are needed to preserve them. The purpose of this study was to determine the morphological and anatomical characters of Dendrobium and Phalaenopsis. This research was conducted in April-September 2021 at the Botanical Laboratory of the Biology Department, University of Lampung. The method used is a paradermal incision on the epidermis of orchid leaves which was observed microscopically, the anatomical quantity, and the image quality. This study used a single factor with two types of orchids used in a randomized block design, as well as qualitative and quantitative variables. The results showed that the two surfaces of Dendrobium had almost the same length and width of stomata, while Phalaenopsis on the lower surface of the leaves had stomata size which was slightly larger than the upper surface. Dendrobium has a hexagonal upper epidermal cell shape, parasite stomata type and the bottom is tetracytic, while Phalaenopsis leaves on the lower and upper surfaces are tetracytic. Stomata are found on the upper and lower surfaces of the leaves of Dendrobium and Phalaenopsis orchids. Based on the research that has been done, there are differences in the number of stomata, the shape of the epidermal cells and the type of stomata on the upper and lower leaf surfaces of Dendrobium and Phalaenopsis orchids.
