Abstract

Study on exploration of mycorrhizal association of terrestrial orchid of Cycloops Nature Reserve, Jayapura was done. Theaims of this study were to collect terrestrial orchid and to isolate orchid mycorrhiza associated with it. Survey method was used in this study. Isolation of orchid mycorrhiza was based on modified methods of Masuhara and Katsuya (1989). The result showed that there were 10 species of terrestrial orchid in this area. Eleven orchid mycorrhizal fungi were isolated from five terrestrial orchids. Among them, 6 isolates were associated with Geodorum sp. From the seventeen mycorrhizal fungi, 3 isolates were identified, namely Rhizoctonia sp., Tulasnella sp., and Ceratorhiza sp, while the last fourteen isolates have not been identified yet. Mostly, each isolate has a specific orchid host, except species G (sp. G) which associated with Phaius sp. and Plocoglottis sp.Key words: terrestrial orchid, orchid mycorrhiza, Mt.

Abstract

Coral reefs play an important physiological and ecological role in coastal ecosystems such as providing natural breakwatersthat protect shorelines and human settlements from waves and storm. Corals killed by tsunami, waves and storms are often degraded into rubble. This rubble is dynamic, easily shifted by currents and storms, which effectively forms ‘‘killing fields’’ forcoral juveniles, hindering coral recovery. In order to rehabilitate coral reefs, artificial substrates are used both for coral transplantation and recruitment. Unfortunately, most artificial substrates are expensive and use land-based material such asconcrete/cement-bases. In order to develop a new low-cost artificial substrate that can replace concrete/cement-base as amedia for coral transplantation, modified coral rubble was tested in a pilot study in Seribu Island, Jakarta. Two different nets (nylon and polyethylene) were used to form rubble into a compact shape, stable and strong substrate. The stability of therubble and the complexity of the surface which is created by the net make this substrate suitable for coral transplantation.Additionally, from an economic perspective the nets are very cheap and locally available. In a number of experiments,modified coral rubble successfully replaced the concrete /cement-base as a media for coral transplantation. The coral transplants were growing over time. With this method, we can try to rehabilitate the degraded coral reef destroyed by tsunami or other factors with material that already is available at the site and with less money. However, this approach requires testing at additional sites and for longer periods, to determine the replicability of the results.Key words: cement base, coral, rubble, transplantation

Abstract

plots. The plots were set up in natural peat swamp forest in the upper catchments of Sebangau, Central Kalimantan. Aim of the study is to understand the dynamics and vegetation changes of forest studied during period of study. The peat swamp forest in the study site might be categorized as moderately forest dynamic in term of rate of growth, mortality and recruitment. Annual relative growth rate and mortality rate was comparable to previous study but recruitment rate relatively higher. There was significant effect of diameter class on annual growth rate, but not to mortality rate. Even not too strong two environment factors (peat depth and distance to river) were significant correlated with rate of mortality and recruitment. During two-year period study there was no significant changes in vegetation structure.Key words: Central Kalimantan, dynamic, growth, mortality, peat swamp forest, recruitment, Sebangau.

Abstract

Indonesia, and in order evaluate genetics diversity of mangosteen and their close relatives, we employed isoenzyme and AFLP marker on 13 accessions of mangosteen and their close relatives. Isoenzyme marker using four enzyme systemsproduced 25 bands and 88% out of them were polymorphic and elucidate genetic variability at similarity level ranged between 0.38-0.89. AFLP markers with three primer system produced 220 polymorphic bands and revealed genetic variability at similarity level ranged between 0.38-0.89 successfully produced high polymorphism bands and elucidates genetic variability at similarity coefficient ranged between 0.21-0.77. Both markers exhibited similar clustering pattern, and group successfully G. mangostana accessions in one clustering group. Furthermore G. malaccensis and G. porrecta consistently showed closer genetic relationship to G. mangostana clustering group in both markers, in comparison to G. hombroniana, which implies the assumption they may be the progenitor of G. mangostana, and should be reviewed with more accurate data.© 2009 Biodiversitas, Journal of Biological DiversityKey words: genetic diversity, mangosteen, isozymes, AFLP.

Abstract

The areas of sago palm (Metroxylon sagu Rottb.) forest and cultivation in the world were estimated two million hectares andpredicted 50% of that areas located in Indonesia. Distribution of sago palm areas in Indonesia is not evenly distributed as well as their diversities. Information of plant genetic diversities and genetic relationship is very important to be used for germplasm collection and conservation. The objectives of research were revealed the genetic relationships of sago palm in Indonesia based on RAPD molecular markers. Fragments amplification PCR products were separated on 1.7% agarose gel, fixation in Ethidium Bromide, and visualized by using Densitograph. Genetic relationships of sago palm in Indonesia showed that sample in individual level were inclined mixed among the other and just formed three groups. Genetic relationship of sago palm population showed that samples populations from Jayapura, Serui, Sorong, Pontianak, and Selat Panjang were closely related each others based on phylogenetic analysis and formed clustered in one group, event though inclined to be formed two subgroups. Populations from Manokwari, Bogor, Ambon and Palopo were closed related each others, they were in one group. Genetic relationships in the level of island were showed sago palm from Papua, Kalimantan, and Sumatra closely related. Sago palms from Maluku were closed related with sago palm from Sulawesi whereas sago palm from Java separated from the others. Based on this observation we proposed that Papua as centre of sago palm diversities and the origin of sago palm in Indonesia. This research informed us the best way to decide sago palm places for germplasm of sago palm conservation activity.Key words: genetic relationships, population, sago palm, RAPD, Indonesia

Abstract

The population and habitat characteristics of Homalomena bellula Schott in Java have received little attention. In this present study, the authors estimated the population density and habitat characteristic of H. bellula in Mount Slamet, Central Java, by means of random samplings of 2 x 2 m2 plots. Two distinct populations were studied at two different altitude levels, i.e. below and above 1000 m asl. We used to suspect that there was a difference in both populations. But our result revealed that these two populations were actually similar in abundance, population density, and dispersion pattern and even in microhabitat characteristics.

Abstract

Degradation of tropical rain forest might exert impacts on biodiversity loss and affect the function and stability of the related ecosystems. The objective of this study was to study the impact of land use systems (LUS) on the diversity and abundance of beetle functional groups in Jambi area, Sumatra. This research was carried out during the rainy season (May-June) of 2004. Inventory and collection of beetles have been conducted using winkler method across six land use systems, i.e. primary forest, secondary forest, Imperata grassland, rubber plantation, oilpalm plantation, and cassava garden. The result showed that a total of 47 families and subfamilies of beetles was found in the study area, and they were classified into four major functional groups, i.e. herbivore, predator, scavenger, and fungivore. There were apparent changes in proportion, diversity, and abundance of beetle functional groups from forests to other land use systems. The bulk of beetle diversity and abundance appeared to converge in primary forest and secondary forest and predatory beetles were the most diverse and the most abundant of the four major functional groups.Key words: beetle, land use system, diversity, abundance, Sumatra.

Abstract

A lot of traditional medicinal plant has antibacterial activities. Most of these plants are freshly chewed or grounded and useddirectly to treat infectious bacterial diseases. However, some practices employ a traditionally spontaneous fermentation onboiled extracted leaf, root or other parts of the plant. This work reports a laboratory stimulated spontaneous fermentation of leaf extracts from selected medicinal plants collected from the Karo Higland. The spontaneous fermentation was stimulated to be carried out by the Acetobacter xylinum and Saccharomyces cerevisiae. The anti-infectious agent activity was assayed on the Escherichia coli growth inhibition. A complementary non fermented leaf extract was also made and assayed as a comparative measure. Indeed, the fermented leaf extract of bitter bush (Eupatorium pallescens), cacao (Theobroma cacao),avocado (Persea gratissima), passion fruit (Passiflora edulis), cassava (Cassava utilissima), diamond flower (Hedyotis corymbosa), periwinkle (Catharanthus roseus), and gandarussa (Justicia gendarussa) have relatively higher anti-E. coli activity than those of non fermented ones. However, there were no anti-E. coli activity was detected in both fermented and non fermented leaf extract of the guava (Psidium guajava) and common betel (Piper nigrum).

Abstract

Gloriosa superba L. is an important medicinal plant of Asia and Africa. It is used in diseases, like cancer, gout, scrofula and act as antipyretic, antihelmintic, purgative and antiabortive. It is a source of colchicines and colchicocides, which are very costly, being highly demanded by pharma industries. Due to excessive use of the plant for diverse medicinal purposes the species is on the verge of extinction and included in Red Data Book. The strenuous efforts of botanists, biotechnologists, policy makers and conservationists are required. It is a matter of great concern to conserve this plant otherwise we will be loosing it by 2020.The present review is focused on current status of the genus, source of alkaloids, poisonous nature, the strategies for its conservation and future perspectives of G. superba.
