Orchids From Mount Sago Nature Reserve, West Sumatera

Mount 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

HOW TO PREDICT THE BLOOMING OF THE GIANT CORPSE INFLORESCENCE Amorphophallus titanum (Becc.) Becc. ex Arcang [Prediksi Mekarnya Bunga Bangkai Raksasa Amorphophallus titanum (Becc.) Becc. ex Arcang]

The giant corpse inflorescence (Amorphophallus titanum) is native to Indonesia. It is one of the flagships of The Center for Plant Conservation Bogor Botanic Gardens, Indonesian Institute of Sciences (LIPI) to raise public awareness for saving plants from extinction and caring the living environment. The blooming of the giant inflorescence attracts many visitors. Therefore, one of the research focuses of Amorphophallus titanum is how to predict the blooming-time in order to inform visitors earlier. The results of this study can be used as the basic information to predict the blooming of the inflorescences. Previous researchers had tried to predict the blooming based on firstly, the differential diagnostics of an inflorescence bud and leaf bud, and secondly, the growth pattern of the flowering bud from one individual sample only; whereas, our results suggested new findings. In this research, the prediction was examined from 2011-2012 on five individual samples planted in Bogor Botanic Gardens. We suggested that (1) the differential diagnostics of an inflorescence bud and leaf bud were not only based on the early bud shapes but also the growth rate, and (2) our results supported Lobin’s findings by providing a statistical formula for growth pattern of the flowering bud

Viability Tests On The Seeds Of Rafflesia Arnoldii R.br. And R. Patma Blume

Rafflesia is a holoparasite that is facing extinction in nature. The Center for Plant Conservation Bogor Botanic Gardens LIPI has been pioneering ex situ conservation using grafting methods. However, ex situ conservation using seed innoculation has been a challenge. Studies on the viability testing of Rafflesia seeds aims to provide viable seeds for supporting the ex situ conservation programs based on seed innoculation methods. In particular, the aims of our recent research were: (1) to investigate the morphological characters of the seeds; (2) to determine a method for viability testing the seeds. The seeds of R. arnoldii and R. patma were used in this research. Firstly, the morphological characters of the seeds were observed under a binocular microscope. The viability test using bioassay procedures was as follows: (1) reagent preparation; (2) pre-staining; (3) embryo exposure; (4) staining, and (5) assessment. The research resulted in: (1) morphological description of the characteristics of Rafflesia seeds, and (2) techniques for bioassay viability testing of Rafflesia seeds

Diversity of Araliaceae in Sulasih Talang Nature Reserve, West Sumatra and its acclimatization

Sulasih Talang Nature Reserve is a conservation area in West Sumatra Province, which contains high diversity of plants including Araliaceae. Araliaceae mostly consist of attractive plants which have potentiallity as ornamental plants. The aim of this research is to record the diversity of Araliaceae in Sulasih Talang Nature Reserve. The result of the study indicates that there are, species of Araliaceae found in Sulasih Talang Nature Reserve, which are : Arthrophyllum diversifolium, Brassaiopsis glomerulata, Brassaiopsis sumatrana var. variaefolia, Macropanax dispermus, Schefflera elliptica, S. farinosa, S. lucescens, S. scandens, Schefflera sp., and Trevesia beccarii, in which Bogor Botanic Garden collected 6 species of them, i.e.: Brassaiopsis glomerulata, Brassaiopsis sumatrana var. variaefolia, Macropanax dispermus, Schefflera elliptica, S. scandens, Schefflera sp. Most of the collections are successfully acclimated in the gardens

Nepenthes diversity in Sulasih Talang Nature Reserve - West Sumatra

Nepenthes is one of carnivorous plants which very popular as ornamental plant. Most of them grow in mountain forest habitat above 1.000 m a.s.l. Sumatra has the richest Nepenthes flora after Borneo, with 29 species. The observation was done in Sulasih Talang Nature Reserve - West Sumatra. According to this inventory in Sulasih Talang Nature Reserve, there are 6 species can be found in this area, which 5 species are endemic to Sumatra, that are N. pectinata, N. inermis, N. bongso, N. spathulata and N. talangensis.
