Anatomical characters can be used to support and strengthen the plant classification. This study aims to determine the anatomical character of the leaves which can be used as a taxonomic identifier at the level of taxa through species representation. A total of 15 species belonging to 12 Indonesian flowering plant families were examined using the paraffin method for the transversal section and HNO3 was used for the paradermal section. Some anatomical characters observed in this study can be used as family characteristics or even species characteristics. The result revealed that all examined samples had similar anatomical characters with previous study which been carried out on the family, genus or species level. These similar anatomical characters consist of one to several characteristic such as stomatal type, anticlinal cell wall, mesophyll tissue, and vascular bundle (petiole and midrib). These results indicate that some anatomical characters can be used as specific characteristics from family level to species level.","PeriodicalId":274763,"journal":{"name":"Buletin Kebun Raya","volume":"117 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121364014","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cibodas Botanic Garden (CBG) seed bank as a part of Kew's Millenium Seed Bank Partnership has also been collecting and banking the seeds of Indonesian native plant species. The study aimed to assess seed availability in nature and collect the available seeds in Selabintana Forest, Mt. Gede Pangrango National Park, West Java, to be stored in the long-term seed storage facility at CBG seed bank. Targeted species for the seed collection were focused on the native trees species with orthodox or approximately-orthodox seeds based on the Seed Information Database (SID) list. Pre-collection assessment and sampling of individuals within a population were using random sampling. Forty seed-producing plant species were reported. Due to the limitation number of seeds in the field (less than 250 seeds), only 33 species were Buletin Kebun Raya Vol.23 No. 1, April 2020 [36–45] | 37 collected. Six species were found with a large quantity of seeds, i.e. Begonia isoptera Dryand. ex Sm., Begonia sp., Ficus fistulosa Reinw. ex Blume, Pinanga javana Blume, Saurauia pendula Blume, and Symplocos sp. Most seeds were collected at 1,100–1,200 m asl, in the forest area, as a tree life form, and majority of the seeds were predicted as desiccation-tolerant (orthodox). Two species, i.e. P. javana and S. cauliflora DC., were listed in IUCN Red List as threatened species. Furthermore, this study demonstrated that high-quality seed collections are needed to ensure the long-term seed conservation.","PeriodicalId":274763,"journal":{"name":"Buletin Kebun Raya","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114532661","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research aimed to develop an optimal and comprehensive protocol for in vitro culture of D. spectabile to support the conservation and reintroduction of this species. The experiment was conducted using a completely random design, including seed sowing, protocorm subculture (subculture 1), plantlet subculture (subculture 2), and plantlet acclimatization. The highest germination rate at 3 MAS (months after sowing) was found in modified Knudson's C (92.59%). The first subculture at 4 MAP (months after planting) showed that the highest leaf and root growths were found in modified Vacin and Went (4.12 and 2.13, respectively). The second subculture at 6 MAP showed that the highest leaf growth was found in full strength of Murashige and Skoog supplemented with 100 g/l banana homogenate (5.49), while the highest number of roots and average root extension were found in half strength of Vacin and Went supplemented with 100 g/l banana homogenate (7.05 and 0.47 cm, respectively).

Propagation programs, both conventional and in vitro culture are necessary to ensure its conservation. The aim of this research is to observe the effects of explant types and plant growth regulator combination (2,4-D and kinetin) in inducing callus from B. bimaensis leaf in vitro. Callus induction was initiated from three parts of leaf explant, namely petiole, leaf base, and leaf lamina. The explants were planted on Murashige & Skoog (MS) medium with addition of 2,4-D and kinetin. Concentrations of 2,4-D were 0, 0.5, and 1 ppm, while kinetin concentrations were 0, 1, and 2 ppm. Each treatment was replicated 10 times. Results showed that leaf base was the best explant used for callus induction. Medium D1K2 (MS + 1 ppm kinetin) showed the fastest time for callus induction that was at 20 days after planting. The highest percentage of callus production (100%) was found on D1K3 (MS + 2ppm kinetin); D2K2 (MS + 0.5ppm 2,4-D + 1 ppm kinetin); D2K3 (MS + 0.5ppm 2,4-D + 2ppm kinetin) and D3K2 (MS + 1ppm 2,4-D + 1ppm kinetin).","PeriodicalId":274763,"journal":{"name":"Buletin Kebun Raya","volume":"242 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114275545","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The demand for this medicinal plant is increasing, both nationwide and worldwide. In contrary to the increasing demands, there are no plantations or such efforts to cultivate this plant to meet commercial needs. Thus, people fulfil the demands by harvesting the plants from its natural habitats in forests. In addition to this lack, there have been forest conversions into other uses such as mining, oil palm plantations and other uses. All those facts result in the decrease of pasak bumi population in the wild, and become the threats for the existence of this species. This study aims to observe the habitat and population of Eurycoma longifolia Jack in its natural habitat at the western block of the conservation forest of PT Sabhantara Rawi Sentosa in Kutai Timur, East Kalimantan. The study applied a transect survey method, comprising five transect lines, each transect contains 10 plots. The results showed that wild population of E. longifolia on the research site was very low. Only one seedling of E. longifolia found in the observation plots, however there were several individuals growing outside the observation plots. Heavy exploitation of the plant and forest conversion into other uses caused the population decrease. Researches to provide bases for commercial plantation of the E. longifolia are strongly recommended to ensure the existence of the species.","PeriodicalId":274763,"journal":{"name":"Buletin Kebun Raya","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132975968","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
