KERAGAMAN GENETIK DRINGO (Acorus calamus L.) BERDASARKAN INTER–SIMPLE SEQUENCE REPEATS (ISSR)
Get PDFDringo (Acorus calamus L.) used as medicinal plant in Indonesian ethnic groups. Those information based on Ristoja (Research Programme on Medicinal Plants) in year 2012. The objective of Ristoja was to provide a database of local ethnomedicine knowledge, herbal formula and medicinal plant in Indonesia. The aim of this study was to assess the genetic diversity of Dringo from 20 selected ethnic groups in Indonesia based on Inter Simple Sequence Repeats (ISSR). Ten selected ISSR primers generated 82 amplified fragments with 51,2% were polymorphic. Dice coefficient was used to calculate similarity index and UPGMA was used to construct a dendogram. The genetic similarity index among accessions ranged from 76,7–100% thus indicating that low level of genetic diversity in Dringo. Genetic diversity database can be useful for medicinal plant mapping and conservation especially for in situ conservation
INVENTARISASI PALEM DI HUTAN BODOGOL, TAMAN NASIONAL GUNUNG GEDE PANGRANGO
Get PDFPalms inventory at Bodogol Forest, Mount Gede Pangrango National Park found 19 species of palms from nine genera. All those 19 species are two species of Arenga, three species of Calamus, two species of Caryota, five species of Daemonorops, one species of Korthalsia, one species of Nenga, two species of Pinanga, one species of Plectocomia and two species of Salacca. One species of Salacca is unidentified, further study is needed to clear up its taxonomy status. Identification key, synopsys of each species and its distribution at Bodogol forest are presented. Conservation status of each species presented

PENYIMPANAN BIJI ANGGREK Coelogyne spp. UNTUK KONSERVASI EX SITU
Get PDFCoelogyne is a native orchid to Indonesia which has a relatively large flower and attractive colors. Coelogyne seed storage needs to be done to conserve the diversity of the species. The experiment of orchid seeds storage on seven species of Coelogyne at temperature -20°C have been carried out for four years at Center for Plant Conservation Botanic Gardens–Indonesian Institute of Sciences. The experimental design used completely randomized design, with media treatment as factors for each species of Coelogyne. Four kinds of media for seed germination test were KCA (Knudson C), KC (modified Knudson C), VW (modified Vacin and Went), and HS (modified Hyponex). Seed viability test was observed after the seeds were stored for 0, 1, 2, 3, 6, 9, 12, 18, 24, 36, 48 months. The results showed that the seed of Coelogyne able to germinate in four experimental media. Coelogyne seed viability declined in three months, six months, nine months, and so on depending on the Coelogyne species. Seeds of Coelogyne which can be stored for 1–2 years were C. pandurata, C. asperata and
rumphii while the seeds can be stored for three years were C. foerstermannii and C. pulverula. Seeds of C.rochussenii and C. celebensis with a short life span should be sown immediately after harvesting, and then preserve them by in vitro culture or by synthetic seeds through encapsulation of protocorm
STUDI POPULASI Dinochloa sepang, BAMBU ENDEMIK BALI
Get PDFAlas bamboo is one of endemic bamboo species grow in protected forests of Sepang Hill, Bali, where in the wild habitat is endangered nowadays. This lianas bamboo was recommended as new endemic species with the name of Dinochloa sepang Widjaja & Astuti, however the population has not been reported yet. An area of one hectare study plot consisting of 10 sub-plots, each measuring 50 m x 20 m was made to determine the existing population. The results revealed that the population of Dinochloa sepang was 360 culms (45 clumps) per hectare including natural regeneration that produced shoots very low at only 32 culms per hectare. Harvested culms i.e. 75 culms per hectare exceeded the number of young culms produced which were 72 culms per hectare. Morphological description of Dinochloa sepang is also discussed in this paper
EXOTIC PLANTS IN THE CIBODAS BOTANIC GARDENS REMNANT FOREST: INVENTORY AND CLUSTER ANALYSIS OF SEVERAL ENVIRONMENTAL FACTORS
Get PDFDue to potential impact of invasive alien (exotic) species to the natural ecosystems, inventory of exotic species in the Cibodas Botanic Gardens (CBG) remnant forest area is an urgent need for CBG. Inventory of exotic species can assist gardens manager to set priorities and plan better responses for possible or existed invasive plants in the CBG remnants forest. The objectives of this study are to do inventory of the exotic species in the CBG remnant forest and to determine whether several environmental variables play role to the existence of exotic species in the CBG remnant forests. There are 26 exotic plant species (23 genera, 14 families) found and recorded from all four remnant forests in CBG. Cluster analysis of four environmental variables shows that clustering of environmental factors of exotic species correlates with the abundances of those exotic species. The relation between environmental factor clusters and the abundance of those exotics signify the role of environmental variables on the existence of exotic plant species. The information of exotic plant species in th
Rafflesia patma (RAFFLESIACEAE): NOTES ON ITS FIELD STUDY, CULTIVATION, SEED GERMINATION AND ANATOMY
Get PDFRafflesia spp. (Rafflesiaceae) have a strategic value from both scientific and conservation viewpoints. To date only very few attempts have succeeded in growing the species ex situ and the main protection measures have been by in situ conservation. More detailed studies are required to understand the relationships between Rafflesia spp. and their host plants in order to improve their management and conservation. Studies on the anatomy, in vitro culture and seed germination in connection with conservation have been conducted in the Bogor Botanic Gardens. Effort to transfer Rafflesia patma to an ex situ conservation area has produced fruitful results. However, we encountered a bigger challenge to maintain the long term presence of R. patma in ex situ conservation, since a high number of individuals is required to make the viable population
