Abstract

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.

Abstract

Climate change, including warming and drying, is currently the biggest challenge for plant regeneration. We conducted two experiments on how temperature affected the germination of Pittosporum pullifolium and P. spicessens, both endemic to Central Papua highlands. P. pullifolium habitat temperature at night could reach 8°C whereas P. spicessens habitat temperature ranged from 19°C early in the morning up to 26°C at midday. The first experiment was to understand the effect of chilling on P. pullifolium germination initiation. Our study showed that P. pullifolium was dependent on cold stratification for its germination. Without cold stratification the germination was absent even though the temperature range of sowing environment is at ca. 13–26°C (Cibodas Botanic Gardens). With a cold stratification at 6–8°C (constant) for more than a month, germination of P. pullifolium occurred, with better germination rate under a light. Subsequently we carried out extended cold stratification for a month and interestingly, the germination still occurred but now it is better under dark condition. For P. spicessens, the germination at its habitat temperature range (Wamena) and in the warmer environment (Bogor Botanic Gardens), both occurred at more than two weeks after sowing.

Abstract

This study was conducted to determine  the effect of growth hormones and mycorhyza application on the growth of ramin cuttings.  A Completely Randomized Design with 5 replicates was used in this study. The experiment consisted of two stages  i.e  hormon treatments (control, Rapid root, Root Up, IBA 250 mg/l, IBA 500 mg/l, IBA 1000 mg/l), Fusarium and mycorhyza applications. The result showed that  the highest number of root  was obtained from Root Up (12,83 cm),  while the lowest was from Fusarium treatments (4,67 cm). IBA 250 mg/l enhanced the number of roots and the length of root significantly  but not stimulate the development of  new leaf.  While mycorhyza application improving  the growth of the new leaf  and  the root development of ramin.

Abstract

After Meijer had conducted ecological study on Mt. Gede Pangrango in 1959, the subsequent study did not monitor its d inamics. This study aimed to compare current vegetation composition and tree structure with past 50 years data based on Meijer publication. One hectare permanent plot reconstructed at submontane zone to identi fy vegetation changes during 50 years on August 2009. Vegetation analyses method was similar with 50 years ago include field tree identification, diameter at breast height (dbh), tree height, and first branch height. Result showed the species richness decreased from 233 to 166 species, diversity index (H) slightly changed from 3.39 to 3.29, and similarity index indicated the differentiation of both tree communities was 51%. Further r nore, from 63 tree species presented in 2009, 47 species was similar with 50 years ago and 16 species know n as new record. Moreover, 18 tree species recorded in 1959 had lost in 2009 i.e., Ehretia javanica, Heli( 7ia javanica, Mischocarpus frutescens, Saurauia bracteosa, Wedlandia glabrata, etc. The highest abundance oi I both studies was Villebrunea rubescens. The changes of vegetation composition and tree structure may have been caused by (1) wind disaster occurred on 1984; (2) human pressured from the nearest village; and (3 ) natural forest regeneration towards climax condition.

Abstract

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 — 0.9 gram and the water content was 26 — 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.

Abstract

Kajian permudaan alami di kawasan hutan Taman Nasional Gunung Halimun–Salak, Jawa Barat telah dilakukan dengan tujuan untuk mengungkap pola dan proses ekologi serta suksesi hutan. Sebanyak 27 petak (10 m x 10 m) telah dibuat dan pada setiap petak dilakukan pengukuran terhadap anakan pohon (diameter 2–5 cm), yang meliputi diameter setinggi 50 cm di atas tanah, tinggi dan posisi di dalam setiap petak. Setiap jenis yang tercatat dibuat spesimen bukti ekologi, untuk identifikasi jenis. Dalam 27 petak tercatat paling tidak sebanyak 73 jenis anak pohon,yang terdiri atas 51 marga dan 29 suku. Macaranga triloba tercatat sebagai jenis dominan hanya pada 9 petak, sedangkan 4 jenis lainnya kurang dari 5 petak. lni menunjukkan adanya variasi komposisi jenis antar petak yang tinggi, yang berkaitan dengan kondisi habitatnya. Adanya penyebaran jenis tertentu pada habitat tertentu pula, menunjukkan adanya keterkaitan antara keberadaan suatu jenis dengan habitat tertentu. Ketinggian tempat dan penutupan kanopi diduga sangat berpengaruh terhadap terbentuknya tipe komunitas.

Abstract

Growing medium is one of the most important factor for ex situ conservation of Rhododendron. Study on different growing media available locally were conducted for germinating and developing the seedlings of Rhododendron javanicum and R. sessilifolium. Tree fern roots medium was suitable for germination and developing Rhododendron javanicum and R. sessilifolium seedlings. Growing medium for bigger seedlings using "Cibodas compost" was better than "Cibodas compost and rice husk" for the development of Rhododendron seedlings. Fertilizer application did not showed significant effect on R. sessilifolium seedlings. However, low concentration of fertilizer was recommended rather than high concentration of fertilizer. Some fertilizers at different applications were tested on the development of R. sessilifolium seedlings.

Abstract

A study on flower biology of Cassine koordersii Kostermans was carried out in the Bogor Botanic Garden on April — 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.

Abstract

Indonesia has high variety of pummelo [Citrus maxima (Burm.) Merr.], but only several cultivar are cultivated extensively. Others became vurnerable and the  germplasm has to be conserved to prevent their extinction. One of the conservation method is in vitro conservation  using a slow growth technique. Factorial experiment was used in designing the experiment, the first factor was MS medium concentration, i.e. 1/2MS and MS. The second factor was sucrose concentration, i.e. 0; 1; 2; and 3%. The results showed that low concentration of MS medium and sucrose reducing the leaf number and shoot length but increasing the root number and length.  Based on inhibition of growth,  the most reducing growth was planlet on MS without sucrose.

Abstract

The last twenty to thirty years can be said to constitute a new renaissance botanical gardens around the world. One of the main causes is the growing concern of the world community associated with the issue of loss of biodiversity. In addition, because a greater need to be institutions that take part actively in the field of conservation of plant resources. Community botanical garden world is experiencing rapid development, not only in terms of the number of new botanical garden that is built up but also of the purpose and function. There are currently no less than 2,500 botanical gardens worldwide. To prepare for a global framework for policies, programs and priorities of the botanical garden world in the field of conservation of biodiversity, in 2000 BGCI has published the International Agenda for Botanic Gardens in Conservation, which contained the botanical gardens global mission.
