Orchids From Mount Sago Nature Reserve, West Sumatera
Get PDFMount Sago Nature Reserve is a conservation site located in West Sumatera Province that was designated as a nature reserve to save its rich biodiversity. The nature reserve holds many plant species that are potential and high values, such as orchids. This study aimed to inventory orchid species from Cagar Alam Gunung Sago using exploratory methods. The study found 47 species comprising 13 species of terrestrial orchids and 34 species of epiphytic orchids. Some of the terrestrial species include Plocoglottis lowii, Goodyera pusilla, Goodyera rubicunda, Crepidium obovatum, Anoectochillus reinwardtii, Corymborkis veratrifolia, Apostasia wallichii and Cymbidiun ensifolium. Some of the epiphytic orchids are Thecostele alata, Coelogyne spp., Cymbidium spp., Trichoglottis simplex, Pinalia flavescens, Bulbophyllum spp. and Flickingeria bancana. Potential ornamental orchids found were Coelogyne spp., Cymbidium spp., Pinalia flavescens and Vanda helvola. The important collections for the Bogor Botanical Gardens were Pinalia flavescens, Plocoglottis lowii, and Vanda helvola
Current Status of the invasive Langkap Palm (Arenga obtusifolia) in Indonesia: Distribution, Impact on Biodiversity and Control Management
Get PDFAs its spread and dominance has negative impacts on diversity, current information on Langkap status in Indonesia is needed in order to control its distribution and protect biodiversity. In the present study, through a comprehensive literature review of published papers and reports, updated information regarding Langkap Palm in Indonesia will be presented. This information includes current distribution of the species, the impact of the species on plant biodiversity, and management approaches used to control the species. The present study found a total of 12 localities in Java and Sumatra Island identified to be the natural habitat distribution of Langkap. The species was known to have dominantly distributed in the half of these localities. To control the distribution of the species, mechanical (trunk cutting) and chemical methods (herbicide application) might be applied.
 
KEANEKARAGAMAN DAN DISTRIBUSI EKOLOGIS Ficus spp. DI KALIMANTAN
Get PDFStudy of Ficus in Kalimantan was carried out by reference study and observation of specimens at Herbarium Bogoriense. Ficus is a large genus with high species member. There are 735 species of Ficus recorded in the world, Malesia region 367 species, Indonesia 252 species, and 138 species found in Borneo. At present, the distribution data (Ficus species) in Borneo island include Kalimantan, Sabah, Sarawak, and Brunei Darussalam. This this study aims to comprehensively reveal the diversity and characteristics of Ficus habitats in Kalimantan. Based on life-form, most of the Ficus in Kalimantan has tree life-form(83 species). Distribution of Ficus in Kalimantan were commonly found at lowland forest in alt. 0-500 m asl. (112 species) and there was no report about Ficus spp. growing at altitude more than 2.000 m asl. About 11 species of Ficus spp. in Kalimantan are also found widespread in Indonesia, there are Ficus ampelas, F. Benjamina, F. caulocarpa, F. drupacea, F. hispida, F. microcarpa, F. septica, F. subulata, F. tinctoria, F. variegata, and F. virens. 37 species are endemic to Kalimantan
Effect of Organic Fertilizer on Growth and Yield of Chili Pepper
Get PDFMany ways to increase the quality and quantity of chili pepper plant, one of them is by doing cultivation techniques improving. The Utilization of organic fertilizer such as compost and manure fertilizer, they can ameliorate soil texture as well as supply macro and micronutrients needed by the chili pepper. The research aimed to study the effect of organic and inorganic combination usage to plant growth and yield of chili peppers. This research arranged in randomized block design in triplicate with six treatment. Factors studied were fertilizers and varieties. There was three fertilizer tested treatment, urea 75 kg/ha + SP36 75 kg/ha + KCl 75 kg/ha (P0), compost+ urea 75 kg/ha + SP36 75 kg/ha + KCl 75 kg/ha (P1) and manure+ urea 75 kg/ha + SP36 75 kg/ha + KCl 75 kg/ha (P2). Two chili peppers varieties used in this research were Lado F1 (V1), and PM999 F1 (V2). Variables observed were plant height, stem diameter, total number of fruit, fruit weight, plant wet and dry weight. The results showed that addition of compost gave the highest growth and yield, followed by manure and control treatments. Lado F1 variety provides higher yields than PM999 F1 variety. The best treatment in this study was combination treatment of Lado F1 variety fertilized with urea 75 kg/ha + SP36 75 kg/ha + KCl 75 kg/ha with addition of 1.35 kg compost per planting hole with the result obtained at 253.35 g of fruit per plant
IRADIASI AKUT DENGAN SINAR GAMMA PADA PROTOKORM ANGGREK Dendrobium macrophyllum A. Richard DAN Dendrobium undulatum M. A. Clem & D. L. Jones
Get PDFIncreasing genetic variation in plants can be done by irradiation technique. The purpose of this study was to improve genetic variation in Dendrobium macrophyllum and D. undulatum orchids by gamma irradiation to obtain superior seeds. Accute Irradiation treatment was perfomed using orchid protocorms. Irradiation doses given: 0, 10, 20, and 25 Gy. The observed parameters were the number of explants, shoots, dead shoots, and leaves at five months after treatment (MAT) and number of roots in seven MAT. Calculation of Lethal Dosage (LD) 20 and 50 was carried out on three MAT. The results of Curve Expert analysis showed that different levels of radiosensitivity in D. macrophyllum were more sensitive than D. undulatum. D. macrophyllum showed LD 20 at an irradiation dose of 13,98 Gy, LD 50 at an irradiation dose 48,42 Gy, while D. undulatum experienced LD 20 at an irradiation dose of 195,67 Gy, LD 50 at an irradiation dose of 490,67 Gy. Acute irradiation effects were seen in protocorm D. macrophyllum at seven MAT in the presence of inhibition at 10 Gy irradiation doses, which was a decrease in the number of shoot of 2,66, decrease in leaf number 18,84 and decrease in root number 5,17 compared to control
Batam Botanic Garden, Indonesia: Recommendation for Its Living Collections from Riau Archipelago Exploration
Get PDFBatam Botanic Garden is a relatively new botanic garden in Indonesia that is assisted by and under collaboration with Bogor Botanic Garden. Recently, a team of Bogor Botanic Garden and Research Center for Biology?LIPI conducted flora exploration in Riau Archipelago, particularly on Karimun Island, Sugi Island and the surrounding areas. The aim of this exploration is to inventory the flora diversity in Riau Archipelago and to enrich living collection of the Batam Botanic Garden. Based on the data gathered from this inventory, we recommend 20 selected plant species with significant conservation value to be targeted for and included in the living collections of Batam Botanic Garden. Five of them (Aquilaria malaccensis, Ceriops decandra, Hopea ferruginea, Pterocarpus indicus and Vatica hullettii) need more attention to be conserved due to their IUCN red list status
INVENTARISASI KEANEKARAGAMAN ANGGREK DAN SEBARAN VERTIKAL ANGGREK EPIFIT DI TAMAN NASIONAL BANTIMURUNG BULUSARAUNG
Get PDFBantimurung Bulusaraung National Park in South Sulawesi shows high diversity of orchids. However, there is no information on vertical distribution of epiphytic orchids from the area. Such information is necessary to understand the habitat preferences of epiphytic orchids, which is required to ensure their ex situ conservation. This research was conducted to determine the orchid diversity and the vertical distribution of epiphytic orchids at Bantimurung Bulusaraung National Park. An explorative method was applied. The study recorded 19 species of orchids in addition to a number of 66 specimens that were identified by generic names. The most common orchids were Dendrobium barbatum Breda, Coelogyne celebensis J.J. Sm., and Phalaenopsis amabilis (L.) Blume. Alstonia scholaris (L.) R. Br. was the most frequent host of the epiphytic orchids in the area. Based on the vertical distribution of epiphytic orchids on its host tree, the epiphytic orchid found in all zones is D. barbatum. Epiphytic orchids were mostly found in zone 3, which is at the bottom of the branching of its host tree
