Abstract

Cytological observations have been carried out by several researchers in South China, Japan, Ceylon, Hongkong, Himalaya and Java. The results from various regions showed that P. multifida had a fairly high genetic variation, namely diploid, triploid and tetraploid types. Therefore cytological and reproductive study on P. multifida from its geographical distribution areas need to be done. The objectives of this research were to observe the somatic chromosome number and reproductive type of P. multifida, and to recognize the relationship between morphological variation and its ploidy level as well as stomatal index. Plants were collected from several localities in Bogor. Ploidy level was determined by observing somatic chromosome number by using squash methods. Reproductive type was determined by counting spore number in each sporangium. Morphological characters examined were the stipe, lamina, pinnae, veins, and indusium. Observations of stomata and epidermis of leaves were done by making an incision paradermal leaf. Pteris multifida has two ploidy level and reproduction type, namely apogamous triploid (2n = 87) and sexual tetraploid (2n = 116). The two ploidy levels could not be distinguished based on morphological characteristics, but they can be differentiated by their epidermal cells number. Apogamous triploid has fewer number of epidermal cells, the sexual tetraploid has a greater number of epidermis.

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

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

There are two species of Jatropha in East Nusa Tenggara (NTT), i.e. physic nut (Jatropha curcas L.) and red jatropha or cotton leaved physic nut (1. gossypilfolia L). Both species possess potency as traditional medicine. Propagating jatropha by seeds could not be conducted throughout the year because the seeds were produced on certain time only. On dry season in 2005, a research had conducted in Teun Village, Belu Regency, NTT for studying the effect of shading and cutting storage on the growth of the two jatropha species. This research had 12 treatments with two replications and employed Factorial Experimental Design. The data were processed by SAS (Statistic Analysis System) program. The result of this research showed that the growth of physic nut better than that of red jatropha. Light shading stimulated the growth of buds, leaves and roots of cutting of jatropha on 60 days after planting. No significant was found in the growth of buds, leaves and roots of cutting of jatropha that were directly planted and stored for four days. Cutting of both species that stored for four days and placed under light shading (with 70% of light intensity) produced higher bud growth and root length than those placed under dense shading (with 30% of light intensity).

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

Target 8 of the Global Strategy for Plant Conservation (GSPC) has a very close link to the works of botanic gardens. It highlights the importance of ex situ collections of threatened plants and their recovery programme. The aim of this paper was to present the Indonesian Botanic Gardens achievements in implementing Target 8 of the GSPC. It is shown that to date 21.5% of Indonesian threatened plants have already been collected ex situ in Indonesian Botanic Gardens. The reintroduction programme was also initiated. In its 14th meeting this year, SBSTTA recommended proposal for an updated GSPC (for 2011-2020), in which the Target 8 was changed to "At least 75 per cent of threatened plant species in ex situ collections" (from formerly 60 per cent). Thus, further work is still needed to increase these achievements.

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

Morfologi kotiledon dari sebelas jenis tumbuhan suku Bignoniaceae diamati sebagai upaya untuk identifikasi lapangan. Kotiledon pada suku Bignoniaceae memiliki karakter unik dan jarang ditemukan pada suku tumbuhan lain. Ujungnya berbelah dua dan berbentuk hati. Karakter unik ini dapat digunakan untuk identifikasi tumbuhan di lapangan, terutama pada fase semai. Sudut kedua parakotiledon, sudut belahan pada ujung para-kotiledon, dan panjang parakotiledon dapat digunakan untuk membedakan tribus dalam suku Bignoniaceae. Namun demikian, penelitian lanjutan yang menggunakan lebih banyak jenis diperlukan untuk menguatkan hasil awal ini.
