Abstract

This study was conducted to collect information regarding carbon storage, particularly the carbon stored in the aboveground biomass as well as in the peat soil. The study site was in a conservation area of the PT National Sago Prima belonging to the PT Sampoerna Agro Tbk. Group. The work was undertaken in January-February 2012. The total aboveground biomass and carbon storage in the research site indicates  that the conservation area is a secondary peat swamp forest, with the biomass of 149.18 ton/ha and carbon stock of 70.12 ton C/ha. The aboveground biomass and carbon consisted of biomass and carbon of tree (83.97 ton/ha containing 39.47 ton C/ha, respectively), saplings (20.69 ton/ha containing 9.72 ton C/ha) and seedlings and undergrowth plants (0.03 ton/ha containing 0.01 ton C/ha), wood  necromass (24.06 ton/ha containing 11.31 ton C/ha), and litter (20.44 ton/ha containing 9.61 ton C/ha). An allometric equation was developed for Pandanus atrocarpus Griff. providing an estimated total biomass and carbon of 5.16 ton/ha containing 2.42 ton C/ha. The underground C with the mean peat depth of 5.5 m, mean bulk density of  0.18 g/cm3, and the mean organic C of 46.6 % was 464.895,94 ton C/ha. In the entire conservation forest area of 541 ha the total aboveground biomassa and carbon storage was estimated to be  80,708.64 ton and 37,934.00 ton C, while the total underground carbon was 238,96 million MT C.

Abstract

Building a new botanical garden is a valuable opportunity that should be implemented as well as possible. The new botanical garden should not simply a clone of the botanical gardens botanical gardens already established, but it should have its own uniqueness, for example in terms of collecting local plant species. There are several things to be considered that the development of new botanical gardens can have a clear direction and goals, including the founding mission of botanical gardens, involvement in conservation and interpretation, as well as the continuity of the existence of botanical gardens in the future.

Abstract

Lygodium circinnatum (Burm.f.) Sw. adalah sejenis paku merambat (Schizaeaceae) yang batangnya banyak digunakan sebagai bahan untuk industri kerajinan tangan. Belakangan ini pasokan bahan bakunya mengalami penurunan akibat menurunnya populasi di alam. Tumbuhan ini belum dibudidayakan, sehingga perlu dilakukan tindakan konservasi termasuk upaya perbanyakannya. Penelitian ini bertujuan untuk mengetahui pengaruh jenis media dan Atonik terhadap perkecambahan spora dan pembentukan sporofit L. circinnatum. Dua jenis media yang diuji adalah: a) lumpur sawah dan b) campuran akar kadaka dan bubuk batu bata. Penelitian dilakukan di dalam rumah kaca menggunakan rancangan acak lengkap. Hasil penelitian menunjukkan bahwa media lumpur sawah secara signifikan berpengaruh terhadap perkecambahan dan pembentukan sporofit, tetapi harus diikuti dengan upaya penjarangan pada sporofit. Tingginya kepadatan sporofit dapat menghambat pertumbuhan gametofit menjadi sporofit. Penggunaan media lumpur sawah yang diberi Atonik pada konsentrasi 1,5 ml l-1 dapat disarankan untuk perkecambahan dan pembentukan sporofit L. circinnatum.

Abstract

The research was conducted to understand seed germination and seedling growth of Artocarpus altissimus. The experimental design used was completely randomized with 2 factors, i.e. seed storability and media factors for the response capacity of germination, media and NPK fertilizer factors for seedling growth response (height and number of leaves). The result showed that A. altissimus seeds had long enough storability/ potential age without a period of dormancy. Storability, media and interaction both showed very significant effect on the germination capacity with the highest mean value on the storability category of 3 and 1 month and media category of compost and sand. On variable of seedlings height, NPK fertilizer showed significant effect, media and interaction of media and NPK had very significant effect with the best factor category was a media category of TSKn (soil, chaff and manure).

Abstract

The Santol fruit (Sandoricum koetjape Burm. f. Merr.) is one of the most important fruit trees in Meliaceae. It possesses seeds with sticky white aril that cannot be stored for a long term because of its characteristic as recalcitrant seeds. The aim of this research was to study the storage period of the santol seeds in the room temperature. Measurements were conducted on seed characteristics such as weight, length, seed thickness, water content, seed viability, and germination rate. The result shows that santol seed can be stored maximum for 40 days. Between 30-40 days the seed can still germinate but the seedling is in normal strong and normal weak category. Based on water content measurement and viability observation, santol seed can be grouped as recalcitrant.

Abstract

Cestrum aurantiacum Lindl. is an exotic species found in native remnant forest of GPNP which is located inside the Cibodas Botanic Garden (CBG). Risk assessment is an important tool to choose best decision for invasive plant management.  Risk assessment analysis on C. aurantiacum in Cibodas Botanic Garden was conducted using Multi Criteria Decision Analysis (MCDA) method.  Analytical Hierarchy Process (AHP) used in the valuation process. Three sub-criteria used: minimizing the ecological impact, minimizing the management cost, and maximizing the public acceptance. Five management alternatives were used: do nothing (DN), eradication (E), containment (C), bio-control (BC) and harvesting (H). Harvesting (H) recommended as the best management decision for C. aurantiacumin at CBG remnant forest. This harvesting decision is not only creating environment/ ecosystem remediation but also as sources of fund in the management activity of the area.

Abstract

Gametofit Asplenium nidus L dari Kalimantan Barat diamati dengan mengecambahkan spora pada media campuran akar paku pohon dan arang sekam (1:1). Penelitian ini bertujuan untuk mendapatkan bukti taksonomi baru untuk mendukung keberadaan jenis komplek dalam A. nidus. Spora coklat tua simetris bilateral yang berkecambah menghasilkan benang berklorofil yang terdiri atas 4-6 sel. Rizoid berkecambah pada sisi polar, sedangkan benang berklorofil pada sisi ekuator. Pembentukan piringan berawal pada sel sub terminal dari benang yang berkecambah pada hari ke-12 dengan pembelahan sel secara mencong. Rizoid terbentuk lagi pada sel-sel pangkal atau semi pangkal pada piringan. Gametofit muda berbentuk jantung panjang dan anteridium muda mulai timbul pada umur 60 hari. Gametofit dewasa menjantung dan menghasilkan anteridium dewasa mulai umur 75 hari. Gametofit hermaprodit dan betina tidak ditemukan. Sporofit muda mulai muncul pada umur 90 hari. Hasil penelitian menunjukkan bahwa ciri-ciri morfologi gametofit menambah bukti taksonomi dalam mendukung keberadaan jenis komplek atau jenis tersembunyi dalam A. nidus.

Abstract

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.
