Abstract

Dendrobium dan Phalaenopsis merupakan sumber daya genetik anggrek  yang semakin langka, sehingga perlu dilakukan upaya pemuliaan untuk melestarikannya. Tujuan penelitian ini untuk mengetahui karakter morfologi dan anatomi Dendrobium dan Phalaenopsis. Metode yang digunakan yakni sayatan paradermal pada epidermis daun anggrek yang diamati secara mikroskopik, kuantitas anatominya, dan kualitas gambarnya. Penelitian ini menggunakan faktor tunggal dengan dua jenis anggrek yang digunakan dalam rancangan acak kelompok, serta variabel kualitatif dan kuantitatif. Hasil penelitian menunjukkan bahwa kedua permukaan Dendrobium memiliki Panjang dan lebar stomata yang hampir sama, sedangkan pada Phalaenopsis pada permukaan bawah daun memiliki ukuran stomata yang sedikit lebih besar dibandingkan dengan permukaan atas. Dendrobium memiliki bentuk sel epidermis atas heksagonal, jenis stomata parasite dan bagian bawah tetrasitik, sedangkan daun Phalaenopsis di permukaan bawah dan atas adalah tetrasitik. Stomata terdapat pada permukaan atas dan bawah daun anggrek Dendrobium dan Phalaenopsis. Berdasarkan dari penelitian yang telah dilakukan terdapat perbedaan pada jumlah stomata, bentuk sel epidermis dan jenis stomata pada permukaan daun atas dan bawah anggrek Dendrobium maupun Phalaenopsis.   Kata kunci: Anatomi, Anggrek, Dendrobium, Paradermal, Phalaenopsis.   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.   Keywords: Anatomy, Orchid, Dendrobium, Paradermal, Phalaenopsis.
变色石斛和蝴蝶兰叶片的定量和描述性形态解剖
石斛兰和Phalaenopsis是一种越来越稀有的兰花的遗传资源,因此有必要进行繁殖来保护兰花。本研究的目的是了解形态学和结构结构的结构和青霉病。使用的方法是用显微镜观察到的兰花叶表皮切口、构造数量和图片质量。该研究采用两种兰花在群体随机设计中使用的单一因素,以及定性和定量变量。研究表明,两层石斛兰表面的长度和宽度大致相同,而叶下表面的咽喉面积略大于上部表面。石斛兰具有表皮细胞的形式红斑出现在石斛兰和红斑莲的上部和下部。根据所做的研究,气孔的数量、表皮细胞的形状和气孔类型在红斑和红斑兰花的上部和下部。关键词:解剖,兰花,石斛兰,皮赘生物,皮赘生物。石斛兰和Phalaenopsis是一种罕见的兰花的遗传资源,所以品种级的努力需要保护它们。这项研究的目的是确定丹德尔比姆和肺炎病变的形态和解剖特征。该研究于2021年4月至9月在楠榜大学植物研究实验室进行。使用的方法是观察小规模、解剖质量和质量的兰花表皮内的寄生虫。这个研究用的是一个单一的因素,用两种兰花的类型使用在一个分散的块设计中,就像分量和数量变化一样。结果表明,这两个嵌板的结构几乎是相同的插孔和宽度的孔,而在底部表层的孔孔比上表面的孔孔更大。石斛兰的上皮细胞形状是hexap,寄生虫样貌和底部是四分体,而红润的表面留下四分体。这块地位于石斛兰和蝴蝶兰的上下部。根据所进行的研究,在表皮的数字、表皮细胞的形状和上叶的结节和下叶鞘的类型上都有不同。安纳托,兰花,石斛兰,皮赘,脑梗塞。
