“…The area is included as sub-montane forest with ranges of altitudes between 900-1500 m asl., represent the secondary forest with domination of Syzygium antisepticum, Weinmannia fraxinea and some of Lauraceae and Euphorbiaceae families (Kurniawan et al 2021). Under the canopy of the area is commonly used by localities as coffee plantation (Figure 2b).…”

A group of the Ficus genus, the strangler figs (Ficus subgen, Urostigma), are known as a more potential as frugivores feed in Mount Ungaran. While the land clearance of the forest into monoculture plantation threats their existence. This study aims to evaluating strangler figs condition by the population study, i.e. densities, distribution, and the demography of each strangler fig species. A total of 25 ha area of Gentong Hill (Northwest part of Mount Ungaran) have been sampled during January-May 2018. We conducted a census of the figs within the sampled area and recorded their life stages in such area. As well as explain the current condition of host tree used by strangler figs in such area. Based on the census that have been conducted, 35 individual belongs to six species strangler figs that equal with 1.4 individual/ha in the value of density is recorded. F. kerkhovenii and the Javan endemic F. involucrata was the commonest species by their densities and abundance. Most of host tree were found dead. The remaining living host tree (16 individuals) are included in three species, i.e. Syzigium antisepticum (14 individual), Weinmannia fraxinea (1 individual), and Engelhardtia spicata (1 individual). Most of the strangler figs found was reached in stage 5 of their life demography, while the stage 1 was the rarest by only 1 individual found. The distribution of strangler figs showed a random pattern. Both of densities and distribution is reasoned by the availability of host tree.

“…Orchids have evolved several remarkable adaptations to cope with environmental conditions (Kaur and Sharma 2021). Indonesia has many wild orchids, with around 5,000 species spread across various habitats (Sjahril et al 2013;Kurniawan et al 2021;Purba and Chasani 2021). Many wild orchid species are endemic to specific regions, and most have yet to be thoroughly investigated.…”

Abstract. Pangastuti A, Pitoyo A, Susilowati A, Meisari R, Yuliana I, Aulia K, Puspitasari LP, Rusiani, Prasojo H. 2023. Diversity of root bacterial community associated with seven orchid species from Mount Merbabu National Park, Central Java, Indonesia. Biodiversitas 24: 5676-5684. Indonesia has a high diversity of wild orchids. One of the orchid habitats that has not been widely explored is Mount Merbabu National Park (TNGMb), Central Java, Indonesia. The dependence of orchids on specific microorganisms for survival and growth, especially during early development, has not been widely studied. Endophytes, such as bacteria, can help the host plant grow, tolerate stress, resist disease, acquire nutrients, or form symbiotic relationships. However, bacterial endophytes associated with orchids have not been extensively explored. This research examined the diversity of bacteria associated with orchid roots in Mount Merbabu National Park using a culture-independent method. Seven orchid species were sampled for root bacterial community analysis, that identified as Spathoglottis plicata, Dendrobium sagittatum, Malaxis kobi, Apendicula alba, Pholidota carnea, Dendrobium tenellum, and Bulbophyllum compressa. Bacterial diversity in all orchid roots was high, with several dominant bacterial species. Proteobacteria, Firmicutes, Bacteriodota, and Actinobacteriota were the four most abundant phyla, with Proteobacteria having the highest abundance (37 to 90%) in all samples. The top ten bacteria genera were Pseudomonas, Serratia, Rhodanobacter, Acinetobacter, Escherichia, Bifidobacterium, Clostridium, Parabulkholderia, Faecalibacterium, and Muribaculaceae family that could not be identified at the genus level. Overall, 61, 42, 838, 98, 78, 973, and 1383 OTUs were unique to S. plicata, D. sagittatum, M. kobi, A. alba, P. carnea, D. tenellum, and B. compressa, respectively, whereas all seven species shared 335 OTUs. Our research suggested that environmental factors and the host plant's genetics affect the plant microbiome's composition and diversity. These elements might be essential for ecosystem function and conservation.

“…However, overexploitation and alteration in land use have caused some orchid species to be vulnerable to extinction. For instance, all of the 115 identified orchid species from Mount Ungaran, Central Java, Indonesia, are listed in Appendix II of the CITES, and four are even listed in the IUCN Red List (Kurniawan et al 2021). On the other hand, some wild orchid species can be potentially used as parental lineages to produce hybrid varieties of desirable better performances, including flower color, shape, and resistance (Li et al 2021).…”

Abstract. Dwiati M, Susanto AH, Budisantoso I. 2022. Somatic embryogenesis of the selected intergeneric hybrid between Phalaenopsis 2166 and Vanda' Saint Valentine': Application of NAA and TDZ. Nusantara Bioscience 14: 160-165. Intergeneric hybridization between Phalaenopsis 2166 and Vanda' Saint Valentine' has produced a hybrid seedling with several characters potentially developing into plant individuals with flowers of better performance. Therefore, identical clones of the selected hybrid should be developed into PLBs using an in-vitro culture technique employing somatic embryogenesis supported by the application of plant growth regulators. This study aims to unveil the effect of NAA and TDZ in stimulating the formation of identical clones of the selected intergeneric hybrid between Phalaenopsis 2166 and Vanda' Saint Valentine'. The experiment was arranged in a factorial Randomized Complete Block Design (RCBD) involving two factors, i.e., types of plant growth regulators and the levels of concentrations of each substance. It was found that the combination of NAA and TDZ significantly affected the growth of the identical clones. Furthermore, the combination of NAA 0.5 mgL-1 and TDZ 1.5 mgL-1 resulted in clones that potentially differentiate into PLBs. This finding indicates that NAA and TDZ should be applied appropriately to stimulate somatic embryogenesis in the intergeneric hybrid.
