A study on seed germination of Kedawung was conducted in the Bogor Botanic Garden using seeds collected from living plant collection of the Purwodadi Botanic Garden. The purpose of the study was to reveal dormancy characteristics of the seed and to search for the effective method of enhancing seed germination of the species. Overall, seventeen treatments of scarification and application of chemical stimulants were tested. The result showed that scarification treatment is critical for promoting Kedawung seed germination. Nicking of the seed testa provided the best result with 80 % seed germination. Soaking the seeds in boiling water also helped the seed to germinate up to 62 %, especially when the time of soaking was appropriate. Meanwhile, the effect of chemical stimulants, i.e. KNO3 and GA3, was evident only if the application was preceded by a scarification treatment. Seed germination was enhanced with the application of either 500 ppm KNO3 or 1500 ppm GA3. These results suggest that the majority of kedawung seeds have physical dormancy (PY), but some may also have physiological dormancy (PD), and only a very little portion of them are evidently non-dormant seeds.

A study on the diversity of epiphytic orchids in the natural forest at the Village Petarikan, District Kotawaringin Barat, Central Kalimantan was carried out. All routes in the area of study were investigated. The number of epiphytic orchids found was 32 genera, consisting of 99 species. The most common species were those of genera Bulbophyllum and Dendrobium. Some of them were endemic to Kalimantan, i.e. Dendrobium nabawanense, Bulbophyllum beccarii, Dendrochilum oxylobum, Liparis lobongensis and Porpax borneensis. These orchids were frequently found on Saraca declinata, Dipterocarpus sp. and Durio zibethinus.

Perkecambahan secara simbiotik pada anggrek Papilionanthe hookeriana dan Taeniophyllum obtusum dilakukan dengan menginokulasi jamur mikoriza dari kedua jenis anggrek ke biji dari anggrek yang sama dan anggrek yang berbeda. Jamur mikoriza diisolasi dan ditumbuhkan pada media isolasi jamur (FIM) dan perkecambahan dilakukan pada media Oat (OM). Empat jenis jamur diisolasi dari akar P. hookeriana, tetapi hanya dua yang tergolong mikoriza anggrek dan hanya satu jenis dari T. obtusum. Ketiga jenis jamur mikoriza tersebut adalah Ceratobasidium sp. yang penampilannya pada kultur murni agak berbeda. Perkecambahan secara simbiotik pada biji dan jamur mikoriza dari jenis yang sama menghasilkan respons yang sama. Akan tetapi inokulasi silang dari jamur mikoriza T. obtusum pada biji P. hookeriana ternyata memberi hasil yang lebih baik ditinjau dari persentase perkecambahan maupun jumlah rata-rata daun dan akarnya dan keduanya berbeda nyata pada taraf p = 0,05. Inokulasi silang sebaliknya tidak memberi hasil yang memuaskan. Bibit anggrek hasil perkecambahan secara simbiotik mempunyai peran penting dalam konservasinya di alam.

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.

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.

Cananga (Cananga odorata) belongs to Annonaceae family. It is potentially used for many purposes, such as for ornamental plant, roadside tree, and timber tree, or as an important component in traditional medicines, traditional ceremonies and the production of some perfumes and biopesticides. As a part of promoting the species conservation and utilization, a study on seed germination of Cananga was carried out in the Bogor Botanic Gardens to observe the viability, germination characteristics and seedling morphology of seeds collected from the Bogor Botanic Gardens plant collection. As many as 450 mature seeds of Cananga were directly sown in three germination beds containing sand medium for germination capacity observation and the other 50 seeds were sown in a separate bed for germinant growth observation. It was noted that seedling emergence of Cananga started at 24 days after sowing and terminated at 45 days after sowing. The total seed germination was 58.05 %. Seedling emergence of Cananga odorata follows an epigeal pattern that shows the leafy emergent cotyledons.

Seed characteristics and seed germination behaviour of Hoya parasitica Wall. (Asclepiadaceae) were observed to study the potentials of the seed for propagation and genetic conservation of the species. Seeds were collected from follicles produced by Hoya collection of Bogor Botanical Gardens. They are small, thin, plumed and showing a comose type. The weight of 100 seeds was 0.7 â 0.9 gram and the water content was 26 â 30% at the time of fruit opening. The water content decreased rapidly to 12.7% and 21.4% after one day of storage in a desiccator containing silica gel and in the open air, respectively. This is in accordance with the natural behaviour of the seed that is dispersed mainly by wind. In general, the seeds were easy to germinate (up to 99% total germination), both in the dark and under natural light, and there was no substantial dormancy encountered during seed germination. The seeds were able to germinate up to 60% while the water content was 3.8%, suggesting the possibilities of long-term storage of the seed for plant genetic resources conservation.

A study on flower biology of Cassine koordersii Kostermans was carried out in the Bogor Botanic Garden on April â November 2002. The plant produces flowers in umbel inflorescences that open sequentially, starting from the lowest branch of the inflorescence. There is no spatial separation between the anther and the stigma, and the dispersal of highly viable pollen takes place within the period of stigma receptivity. The flowers also show some characters of entomophily. Visitor insects are flies (ordo Diptera, family Syrphidae and Tachinidae) and ants (ordo Hymenoptera, family Formicidae). In general, the morphological and phenological characteristics of the flower allow self pollination to occur successfully. Floral assessment using Crudens Outcrossing Index showed that the flower is self-compatible.

Pengamatan sitologi dan kromosom somatik dilakukan pada 23 individu dari enam jenis tumbuhan paku genus Pteris (Pteridaceae) yang tumbuh meliar di Kebun Raya Bogor. Hasil pengamatan menunjukkan bahwa jumlah kromosom dasar pada keenam jenis Pteris yang diamati konsisten, yaitu x = 29. Ras diploid dengan 2n = 58 ditemukan pada P. biaurita, P. fauriei dan P. tripartita. Ras triploid dengan 2n = 87 terdapat pada P. fauriei dan P. multifida. Sedangkan ras tetraploid dengan 2n = 116 ditemukan pada P. ensiformis, P. tripartita, dan P. vittata. Informasi tentang P. tripartita ras diploid dan P. multifida ras triploid dilaporkan pertama kali untuk kawasan Malesia. Sedangkan informasi kromosom P. fauriei, P. multifida, dan P. vittata merupakan catatan sitologi baru untuk Pulau Jawa. Jenis-jenis yang memiliki lebih dari satu sitotipe diamati morfologinya dan dibahas secara singkat.
