INTRODUCTION Indonesia is a mega biodiversity country, rich in biodiversity both flora and fauna. The wealth of biological natural resources has functions and benefits as an element of the environment that can not be replaced. Biological Diversity or often referred to as biodiversity is a term to express the level of biodiversity of natural resources which includes abundance or distribution of ecosystems, species and genetics. Based on Law No. 5 of 1994 concerning ratification of the United Nations Convention on Biological Diversity (biodiversity convention) that is meant by biodiversity is diversity among creatures from all sources, including, land, sea and other aquatic ecosystems and ecological complexes which is part of its diversity, including diversity within species, between types and ecosystems. The impact of forest exploitation in addition will cause environmental degradation in the form of forest destruction, water and air management, and will also threaten the destruction of a large number of flora including germplasm of epiphytic orchids. It is feared that the diversity of germplasm will decrease due to disturbance to their habitat. http://iaeme.com/Home/journal/IJARET 185 [email protected] Sosilawaty Sebangau National Park covering ± 568,700 ha located on the Katingan River and Sebangau River has a high level of biodiversity including 116 species of flora, 116 species of birds, 35 species of mammals, 26 species of fish and others. Punggualas is one of the locations in the Sebangau National Park area which has a high biodiversity potential and in its management has been projected for ecotourism activities. Some communities in the Sebangau National Park area, especially in the village of Karuing, the Punggualas area do not know well or in detail that the orchid plants are so many benefits, and orchid plants are now threatened with extinction, but the population and species diversity are not known with certainty. On the other hand the rate of forest destruction is increasing from year to year and excessive use will be able to threaten the preservation of orchid plants in the forest. The aim is to find out the diversity of orchid species, species evenness, and dominance found in the Sebangau National Park at the Punggualas Resort Baun Bango Resort SPTN Region III Kasongan, Central Kalimantan Province. This research is expected to provide information on diversity, wealth, and evenness of orchid plants for the community, agencies, researchers, and the government or the private sector to be used as reference material for management and development. In addition, it can involve the community in the maintenance of orchids in the Sebangau National Park at the Punggualas Resort Station, Baun Bango Resort SPTN Region III Kasongan, Central Kalimantan Province. 2. NATIONAL PARKS National Parks are nature conservation areas that have native ecosystems, managed with zoning systems that are utilized for research, science, education, tourism and nature recreation purposes. National Parks based on article 1 of Law No. 5 of 1990 concerning Conservation of Biological Natural Resources and their Ecosystems, in paragraph 14, is defined as a nature conservation area that has native ecosystems, managed with a zoning system that is utilized for research, science, education, supporting cultivation, tourism and recreation. Criteria for the Establishment of National Park Areas (TN) are as follows: Specified areas have sufficient area to ensure the continuity of natural ecological processes: a. Having unique and unique natural resources in the form of plants and animals and their ecosystems and natural phenomena that are still intact and natural. b. Have one or more intact ecosystems. c. Having a state of nature that is original and natural to be developed as natural tourism. d. It is an area that can be divided into Core Zones, Utilization Zones, Jungle Zones and other Zones which, due to consideration of the importance of rehabilitation of the area, dependency of the population around the area, and in order to support the preservation of biological natural resources and their ecosystems, can be designated as separate zones. National Park Management can provide benefits such as: the economy can be developed as an area that has economic value, for example the potential of coral reefs is a source that has high productivity and diversity that helps increase income for fishermen, coastal residents and even foreign exchange. The National Park area is managed by the government with efforts to preserve the diversity of plants and animals and their ecosystems. A national park area is managed based on a management plan prepared based on a study of ecological, technical such as pollution control (Mangkoedihardjo and Triastuti, 2011), economic and socio-cultural aspects. The http://iaeme.com/Home/journal/IJARET 186 [email protected] Identifying the Diversity of Orchids in the Sebangau National Park in Central Kalimantan national park management plan at least contains management objectives and an outline of activities that support efforts to protect, preserve and utilize the area. 3. ORCHID 3.1. Description A plant is identified based on the shape of the leaf, the location of the leaf on the stem, stem, roots, flowers, and fruit. Every plant has these parts. In certain plants, these parts have been modified according to their environment, the main distinguishing feature of plants is the flower. A. Interest Like other flowers, orchids consist of five main parts, namely sepals, petals, stamens, pistils, and ovaries. The outer flower protector when the flower is still a bud is sepals. Orchid has three beautiful colored sepals, different from other flower sepals which are generally green. Its location forms a triangle. In certain types of orchids, such as the Slipper Orchid, the sepals below link together. In addition to sepals, orchids also have three petal strands that are also positioned to form a triangle. The two strands above form an angle of 1200 with a larger 3rd sheet called the labelum or lip. There are orchids that only have one stamens (monandrae), but there are also those who have two stamens (diandrae). Stamens and stems of the pistil together form a structure called a column. The head of the pistil is located under the cap and polinia, facing the labelum. It seems like a shallow hole that is round and rather sticky. The flower ovary is located under the crown structure. This position is called inferior ovary. This ovary is usually united with a flower stalk. There are orchids that are formed at the tip / tip of plants such as Cattleya, Oncidium, and Coelogyne. Another group is the flower that forms between the leaf blades called pleuranthe, as in the Dendrobium, Vanda, and Ascocenda plants. B. Fruit The orchid is a capsular fruit which is divided into six parts. The seeds are in the fruit and very much. These orchid seeds do not have endosperm (food reserves) like other plant seeds. Therefore, for the germination and initial growth of orchid seeds need sugar and other compounds from outside or from the surrounding environment. C. Leaves The shape of the leaves varies, from narrow to elongated. As in general monocotyledonous plants, orchid leaves do not have spread-shaped leaf bones, but their leaf bones are parallel to the leaf blade. Leaf thickness also varies from thin to thick fleshy (succulent). Vanda leaves even round like a pistil. The leaves attach to the stem with the position of one strand in each book and face the leaves in the next book or in pairs, ie in each book against the two strands that face each other. C. Rods There is a single orchid stem with the end of the stem growing straight unlimited. Old leaves on the lower trunk will fall. After the leaves fall, the stem looks like dead. This pattern of growth is called monopodial growth. Some types of orchids that have such patterns are Vanda, Arachnis, and Aranda. This stem grows continuously and will stop after reaching the maximum limit. In this sympodial orchid there is a connector called rhizoma or stem. From this rhizoma new shoots will emerge, for example in the Cattleya orchid. In Cattleya, between rhizomes and leaves there is a kind of tuber called pseudobulb. http://iaeme.com/Home/journal/IJARET 187 [email protected] Sosilawaty D. Root Epiphytic orchid roots are generally soft and break easily. The tip is tapered, slippery, and slightly sticky, the orchid root has a layer of velamen that is hollow and underneath is a layer containing chlorophyll.

  • Orchid Research Newsletter 75 (PDF)
    Orchid Research Newsletter No. 75 January 2020 Editorial Orchids are perhaps not the first thing that comes to mind when we think about climate change. Record temperatures, catastrophic droughts, melting glaciers, out-of- control bush fires, burning rainforests and other calamities are of more immediate concern. But when we focus on orchid conservation, it is obvious that climate change looms large. It seems likely that orchids are more vulnerable to climate change than most other plant groups, for the following reasons: (1). Since about 70% of all orchids are epiphytes, they are probably more likely to be affected by drought. Even if mature plants would be able to survive unusually severe droughts, one can imagine that seedlings would be much more vulnerable. If such droughts become too frequent, seedling recruitment will be compromised, and the orchids will die out. (2). Since all orchids go through a mycoheterotrophic stage, at least as as seedlings, they depend on the presence of the right fungi for their long-term survival. It could be that climate change affects these fungi in such a way that they are no longer available to particular orchid species. These will then gradually disappear from their habitats. (3). Similarly, since many orchids depend on highly specific pollinators, the effect of climate change on the availability of these pollinators may be significant. A chain is only as strong as its weakest link, and we do not know if it is the orchid, the fungus or the pollinator that is the weakest link. (4). Orchids tend to occur in sparse, widely dispersed populations.

CAMERON The Lewis B. and Dorothy Cullman Program for Molecular Systematics Studies, The New York Botanical Garden, Bronx, New York 10458-5126, USA ([email protected]) ABSTRACT Parsimony analyses of DNA sequences from the plastid genes atpB and rbcL were completed for 173 species of Orchidaceae (representing 150 different genera) and nine genera from outgroup families in Asparagales. The atpB tree topology is similar to the rbcL tree, although the atpB data contain less homoplasy and provide greater jackknife support than rbcL alone. In combination, the two-gene tree recovers five monophyletic clades corresponding to subfamilies within Orchidaceae, and fully resolves them with moderate to high jackknife support as follows: Epidendroideae are sister to Orchidoideae, followed by Cypripedioideae, then Vanilloideae, and with Apostasioideae sister to the entire family.

Mansf. in in vitro culture. The seeds were obtained from a sterilised orchid capsule. They were sown on a Murashige and Skoog medium + indoleacetic acid (1.5 mg dm-3) and benzylaminopurine (2.0 mg dm-3) without the addition of activated charcoal and on a medium that contained 1.0 and 3.0 g dm-3 activated charcoal, respectively, for 18 months. Initial differences in seed germination were observed after nine months since the beginning of the in vitro culture. The addition of activated charcoal had a positive influence on protocorm size and development. The results of this research were confirmed after 12 and 18 months of in vitro culture, where an intensive development of leaf and aerial roots occurred on a medium that contained the highest concentration of activated charcoal, i.e. 3.0 g dm-3 as a supplement.
