BERITA BIOLOGI Vol 6, No 3 (2002)
Publisher : Research Center for Biology-Indonesian Institute of Sciences

A study on the mycorrhizal status of plants growing in an urban forest reserve which has still patches of remnant native vegetation was conducted in the Gresswell Nature Reserve at Bundoora, Victoria, Australia.The results showed that there were 24 families comprising 53 species.Of the 53 species,32 had AM alone, 15 had AM and ectomycorrhiza,one had ectomycorrhiza alone and five were non-mycorrhizal. There were 26 taxa AM fungi associated with plant roots i.e.,four taxa of Acaulospora, one of Entrophospora, 19 of Glomus and two of Scutellospora.

This study was conducted to know of potential of natural resources of Mt.Halimun used by surrounding communities and the development of bufferzone.The potential of natural resources are composed of wildlife, plant biodiversity,land and hydrology.Then, The utilization of natural resources will be correlated with the condition of socio economic and culture of communities.According to the study, it is known that the major occupation of the village communities are as farmers, who have private land or as laborers (>50%). As laborers, they worked for landlord with salary Rp. 5,000 to Rp 10,000 per day for six days per week. This condition made village communities to depend their livelihood to potential of natural resources of Mt. Halimun NP. Based on dynamic hypothesis,the bufferzone could be developed through data and information of the natural resources that utilized or disturbed by communities. The plant biodiversity are used as energy, traditional medicines, food, handicrafts and forages.Illegal hunting done by surrounding communities was hunting wild pigs, birds and monkeys.To limit the exploitation, illegal cutting, illegal hunting and deforestation The Mt Halimun NP have program social forestry and agroforestry to decrease dependency of communities to the forest. For example the sheep breeding with forage plants in bufferzone.Other programs such as goats breeding and fish or plants development could be done in border land of national park or private land of communities.

Study on rattans density in 11 locations in the Gunung Halimun National Park (GHNP)had been conducted. Observation had been made in rectangular plot transects of 20 m wide, namely of 500 m long near Cisungsang Village (alt.700 m), 500 m long near Cikidang Village both were in Lebak District, 3650 m long in Gunung (= G) Botol and surroundings (950 - 1750 m asl) including Cikaniki (950 - 1300 m asl) in Bogor District.The plots were located in 6 places. The results had been compiled with previous data from G. Kencana, G.Pameungpeuk, and G. Pangkulahan all from the same park. It was concluded that GHNP had 13 species of rattans.Two dominant species were Calamus heteroideus which had average density (=D) 208 individual stem (= st)/ha and C.javensis D = 84 st/ha. Species distribution was so diverse. Java had 25 species, among them 9 species were endemic, three species among the endemic ones were in GHNP. People in Cisungsang Village were keen to establish local rattan gardens to support their sustainable rattans home industry. Five species have been in their concern.Prospect of rattan cultivation were discussed, as well as regarding an application of their vernacular names.

KAJIAN EVALUASI LAHAN UNTUK PENGEMBANGAN CENDANA DINUSA TENGGARA TIMUR Hendrisman, Marwan; Sosiawan, Hendri; Irianto, Gatot

Komoditas kayu cendana menyumbangkan Pendapatan Asli Daerah (PAD) sampai 40% untuk Propinsi Nusa Tenggara Timur (NTT),sehingga dapat dijadikan komoditas andalan bagi Propinsi ini. Pulau Sumba dan Pulau Timor diduga merupakan tempat asal tumbuh cendana, sehingga untuk pengembangan budidaya cendana dapat dicari daerah yang mempunyai ekosistem yang mirip dengan daerah asalnya.Teknologi budidaya tepatguna bagi cendana perlu dikembangkan untuk memperluas areal tanam komoditas tersebut.Untuk itu perlu dibentuk suatu dewan riset cendana secara lintas sektoral dari berbagai disiplin ilmu.

STRATEGI KONSERVASI IN-SITU EBONI BERGARIS/ KAYU HITAM MAKASSAR {Diospyros celebica Bakh.) DI SULAWESI Achmad, Amran

Gap analisis digunakan untuk mengevaluasi tipe habitat, status hutan, tutupan hutan dan sebaran Diospyros celebica di Sulawesi.Hasil analisis menunjukkan bahwa 18 tipe land system (habitat) yang ditumbuhi Diospyros celebica dengan status hutan produksi terbatas, hutan produksi biasa dan hutan produksi konversi, serta delapan di antaranya berada dalam areal HPH.Oleh karena itu perlu diusulkan untuk ditetapkan statusnya sebagai kawasan perlindungan sumberdaya genetika D.celebica.Hasil analisis ini juga menunjukkan bahwa beberapa kawasan/ hutan lindung yang diketahui ditumbuhi oleh jenis D.celebica tidak lagi memenuhi syarat untuk fungsi konservasi in-situ, sehingga perlu dievaluasi ulang, baik dari segi luasan maupun dari segi kualitas tutupan dan potensi hutannya, sehingga fungsi konservasi terhadap jenis D. celebica lebih optimum

PERBANYAKAN TANAMAN WIEP {Grevillea papuana) SECARA KULTUR JARINGAN Sukamto, L Agus
BERITA BIOLOGI Vol 6, No 5 (2003)
Publisher : Research Center for Biology-Indonesian Institute of Sciences

The population of wiep (Grevillea papuana) originated from Papua, decreased because of over cutting or over exploitation for timber, ornamental or medicine. Experiment was carried out to propagate wiep by using tissue culture method. Hypocotyls, cotyledons and nodes from seedlings grown in vitro, were used as explants. These explants were grown on Murashige & Skoog medium which macro and micronutrients were half strength, with or without hormones (BA 1 mg/1, BA 1 mg/1 + NAA 0,5 mg/1, BA 2 mg/1 + NAA 0,5 mg/1, BA 1 mg/1 + 2,4-D 0,5 mg/1, and BA 2 mg/1 + 2,4-D 0,5 mg/1).All explants did not produce callus on medium without hormones, but produced callus with hormones except BA treatment on cotyledon explants. Bigger callus were produced by explants that were treated by combination BA with NAA or 2,4-D compare to those treated by BA only. Nodes and hypocotyls could produce shoots, but cotyledons did not. Three kinds of explants did not produce any roots. Node is the best explants for producing shoots.Combination of BA 1 mg/1 and 2,4-D 0,5 mg/1 caused synergistic effect to stimulate shoot production of wiep hypocotyls explants.

A study on the distribution and abundance of high mountain rat was carried out at Gunung Botol, Gunung Halimun National Park.Observation was conducted at three stations located at the mountain top, middle and foot of the mountain.The results indicated that four species of rat were recorded from Gunung Botol, namely Maxomys bartelsii,Niviventer lepturus, Niviventer fulvescens and Niviventer cremoriventer.Our data showed a relationship between number of individuals observed of each species with altitudinal gradients.While estimation of murid rodent population between altitudinal changes indicated there was no differences between the stations observed. An analysis was conducted to investigate any possible association between rat abundance against environment factors that could associate with altitude.The results indicated that ground covering and tree circumference, as well as interspecific competition seemed to be important factors in influencing the differences in distribution of each rat species.

The accuracy of the parentage reference is the early step of information needed for genotyping study.Inaccurate data of recording sheep numbers is often occurred. Sometimes, we found sheep or lambs with uncertain original parents. This study was designed to identify the parentages of sheep and to find the putative parents of lambs. Using an advance DNA technology in molecular genetics particularly in genotyping study, those purposes can be clarified. DNA of sheep were isolated from fresh blood samples in EDTA using a high salt method. A concentration of 50ng/(il DNA was used for amplification. Several microsatellite markers were applied in the amplification. Using a DNA analyser and sequencer, PCR products were analysed to look at the figures of alleles (bands). Results showed that using microsatellite markers could inform that parents of several experimental lambs were incorrect. It was found that putative parents of some lambs were generated from incorrect parents. This study suggests that microsatellite marker can be used to clarify unknown original parents.
