Abstract

Jernang (Daemonorops draco (Willd.) Blume) is a dioecious rattan species that produces resin on female individuals. The sex of jernang can only be identified from its inflorescences morphology. Sex survey was conducted in 5 populations of  jernang, 3 populations of which in the Bukit Tigapuluh National Park (BTNP), 1 population in the secondary forest in Jambi province and 1 population in the area of rubber plantation in Jambi province. Chi-Squared test on the sex ratio of  jernang showed that the ratio of the male to female in their natural habitat (Bengayoan and Tebo, 2 parts of the BTNP ecosystem and the Sepintun secondary forest) was distorted from the normal ratio of 1:1, while the cultivated jernang in Nunusan population (BTNPT) and Mandiangin were not significantly different from the normal sex ratio of 1:1. Female individuals from the cultivated population in the Mandiangin (planted in 1997) has an average number of stems per clump more on individual males (27.12) than females (26.92). The result of this study indicated that the D. draco has a good reproductive strategy and thus suitable for cultivation.

Abstract

Interaction between epiphyte Hoyo diversifolia Blume (Asclepiadaceae) and ants (Formicidae) was observed in Bogor Botanical Garden. Five species of ants were noted to be involved in the interaction, namely Acropygo sp., Pseudolosius sp., Oecophylla sp., Myrmoteros sp. and Euprenotepis sp. They exhibit a mutualism symbiotic interaction in an optional (facultative) manner. The ants take some advantages of floral and extra floral nectarines for food and apparently receive protection for their nests by seedlings of H. diversifolia. Meanwhile seed of H. diversifolia is carried out and dispersed by ants to some favourable sites to grow.

Abstract

Red listing is a critical point in implementing conservation strategy of Indonesian Rhododendron spp. Some problems might be encountered during the process. Firstly, many of Indonesian Rhododendron species are on data deficient status, especially for non-Java species. Secondly, the existence of unstable species list that contains species names only known from few specimens. Thirdly, the legality of the conservation status for natural hybrids. Thus, promoting their natural habitat conservation and make them as monitoring remote areas for botanic gardens would be an important part of the conservation strategy.

Abstract

Buah avokad mempunyai kandungan nutrisi yang sangat baik bagi masyarakat khususnya kandungan lemak tidak jenuh dan protein yang tertinggi bila dibandingkan jenis buah lain. Untuk tujuan komersial, tanaman avokad perlu diperbanyak secara vegetatif untuk memperoleh bibit yang telah terbukti kualitas dan kuantitas tinggi, serta berbuah lebih awal. Keberhasilan penyambungan sangat dipengaruhi oleh kesegaran entres. Penelitian ini bertujuan untuk mengetahui keberhasilan dan pertumbuhan sambungan tanaman avokad dengan menggunakan entres yang disimpan dalam pelepah batang pisang selama dua hingga sembilan hari. Parameter pengamatan meliputi persentase tingkat hidup sambungan, pertumbuhan panjang, jumlah daun, jumlah cabang, dan panjang percabangan batang atas setiap bulan sampai enam bulan. Data pertumbuhan dianalisis secara statistik dengan ANOVA dan uji lanjut Duncan. Lama penyimpanan entres berpengaruh terhadap tingkat hidup hasil sambungan dan pertumbuhan batang atas avokad. Rerata tingkat hidup bibit sambungan avokad terus menurun dari 99,5% pada umur satu bulan sampai 71% pada umur enam bulan setelah penyambungan, tetapi tidak mengalami penurunan setelah lima bulan penyambungan. Penyimpanan entres avokad dalam pelepah pisang dapat dipertahankan kesegarannya selama sembilan hari, yaitu tingkat hidup sambungan 60% - 84% enam bulan setelah penyambungan. Ada kecenderungan bahwa makin lama penyimpanan entres, makin menurun pertumbuhan batang atas avokad; sebaliknya makin lama umur penyambungan, makin meningkat pertumbuhan batang atas avokad, kecuali jumlah cabangnya yang relatif tidak meningkat setelah dua bulan penyambungan.

Abstract

Ramin (Gonystylus bancanus) is one of the major timber species that facing high exploitation in Indonesia. This species can only be found on a specific peat swamp habitat, thus it confines its distribution. Information on its current population and microhabitat characteristics is relatively limited. Here, we investigated natural population and microhabitat of ramin in a peat swamp area in Riau Province using  random transects consist of 46 (100m2) sampling plots. Forty-eight individuals of ramin were found in which 46 of these belonged to G. bancanus, while the other two were different species. The estimated population density of ramin in this area was 7.18±2.75 individuals/ha i.e there were approximately seven individuals in each one-ha area of study. The population structure of ramin showed a J-shaped curve bearing many large old trees with few saplings without any seedlings. The microhabitat was investigated using the Discriminant Function Analysis (DFA) and Canonical Analysis, generating two significant variables that discriminated three groups of the population.

Abstract

Malesia is the center of Dipterocarps diversity in the world, with most species found in Indonesia. Sadly, their existence is threatened by illegal logging, extensive exploitation, and habitat conversion. There are 143 Indonesian Dipterocarps categorized as threatened in the IUCN Red List. Bogor Botanic Garden (BBG) is one of the leading institutions focuses on ex situ conservation of plants. Dipterocarps collection in the BBG represents 41.5% of Dipterocarps of Sumatra, 17.0% of Dipterocarps of Kalimantan, 77.8% of Dipterocarps of Java, 66.7% of Dipterocarps of Bali and Nusa Tenggara, 57.1% of Dipterocarps of Sulawesi, 66.7% Dipterocarps of Moluccas, and 8.3% Dipterocarps of Papua. Totally, BBG has only conserved about 37.8% of threatened Indonesian Dipterocarps, still far from the target aimed by the Global Strategy for Plant Conservation (60% conserved). The BBG has initiated genetic resource conservation of Dipterocarps, through seed preservation. Since most Dipterocarps have recalcitrant seeds, conventional storage methods cannot be used. One of the alternative solutions is to cryopreserve the excised embryo or embryonic axes to overcome the limits of conventional storage methods. Collection of threatened and endemic species along with research on embryo culture and cryopreservation should be intensified in the future.

Abstract

Yam (Dioscorea alata L.) is a potential local crop for supporting food security program in Indonesia.  Inventory and characterization of yam have been conducted in scattered population at Nganjuk region - East Java.  The research was aimed to identify the characteristic of Nganjuk’s yam, based on the tuber morphology and to determine its similarity distance value.  The characterisation were analyzed using interval similarity function, based on NTSys DICE coefficient programme. The result showed that 22 accession numbers which comprises of 13 variants of yam were found in Nganjuk region. The same variants of yams indicated by their close similarity distance although they were originated from different areas.
