Cendana (Santalum Album ) dan Keanekaragaman Inang Sekundernya di Daerah Pesisir Kolbano, Nusa Tenggara Timur

Sandalwood (Santalum album ) and diversity of their host secondary in Kolbano Village, Lesser Sunda Island. The population of sandalwood (Santalum album ) declined every year because is not cultivated yet by the local people. Inhibiting factors are not possess the knowledge and skills on sandalwood cultivation especially in host plant of sandalwood comprehension. Forest fire and illegal logging lead to lose of flora diversity and deteriorate of sandalwood growth. Result of this research shows that population of sandalwood in Kolbano Village is very low are four plants in Kampong Fatu Un and seven plants in kampong Spaha. In kampong Fatu Un was found eight species plant that compose to unity formation with sandalwood and seven species of them are secondary host of sandalwood. In kampong Spaha was obtained nine species plant that compose to sandalwood formation and seven species of them are secondary host of sandalwood. The highest distribution frequency of plant in two mentioned kampong was got by leucaena (Leucaena glauca) plant with respectively value 51.28% (Fatu Un) and 53.57 % (Spaha), whereas diversity value belong to Simpson Index were 0.71 (Fatu Un) and 0.64 (Spaha)

Keragaman Fenotipe Rapd Santalum Album L. Dipulau Timor Bagian Timur [Rapd Phenotypic Variation of Santalum Album L. in Eastern Part of Timor]

Santalum album L. (sandalwood/cendana) is known as one of medicinal and aromatic tree species in Indonesia. The species is valued for its quality light wood timber and for its medicinal properties.The species has been overexploited and is considered as vulnerable plant species.The present study aimed to assess genetic diversity and to estimate genetic relationship among 58 accessions of plant germplasm collection using Random Amplified Polymorphic DNA (RAPD).Two RAPD primers generated 34 scorable bands with 97.06% of them were polymorphic. Clustering analysis was performed based on RAPD profiles using the UPGMA method.The range of genetic dissimilarity value among species was from 6% to 91%, while the range of genetic distance between populations was from 1.89% and 26.88%.These values showed that 5.album from Eastern part of Timor was genetically diverse populations.Within the 12 populations, there were 9 banding patterns recorded from primer OPA 16 and 12 banding patterns from primer OPB 12, suggesting that OPB 12 was more sensitive than that of OPA 16 to show variation within the sample used

Variasi Karakteristik Pertumbuhan Tacca Leontopetaloides (L) Kuntze (Taccaceae) Di Pulau Jawa Dan Pulau-pulau Kecil Sekitarnya [Growth Characteristics Variation of Tacca Leontopetaloides (L.) Kuntze (Taccaceae) in Java and Surrounding Islands]

An increasing of population, land conversion, and the behaviour changes in many crops due to global warming could produce a significant negative effect to food security in many countries, including Indonesia. In order to maintain the availability of food, we should find out alternative foods based on corp comodities that can adapt to future agricultural land conditions. One species to be promoted for that purpose is Tacca leontopetaloides (taka). This study was aimed to determine growth characteristics variations of taka in Java and its surrounding small islands through exploration and interview methods. Results indicated that there were two morphological variations of taka based on the canopy colour, namely green and purple. Taka found growing in coastal areas up to100 m above sea level. The light intensity and soil type greatly affected their growth. These plants lived either solitary or in a groups, grow well on sandy soil to clay, under the shade and open areas. Species around taka allegedly contributed in determining taka growth and production. Taka tuber can be an alternative carbohydrate source for supporting food self-sufficiency in coastal communities

Sandalwood as a Component of Agroforestry: Exploration of Parasitism and Competition with the Wanulcas Model

Sandalwood is an important component of agroforestry systems in the drier Eastern parts of Indonesia, although its value to farmers is still limited by existing policies and regulation of marketing. As a relatively slow growing root parasite, sandalwood will interact with other components in a complex pattern of competition and host-parasite relationships, depending on root distribution and rooting depth of potential hosts. We describe a number of modifications to the generic tree-soil-crop simulation model WaNuLCAS, that allow exploration of the transition between parasitism and competition. The key variable in this transition is the effectiveness of formation of the parasitic link for all situations where roots of the host and parasite occur in the same volume of soil. At low values of this effectiveness competition dominates, at higher values sandalwood will weaken the host, until it effectively kills it, leading to an optimum response of sandalwood to the effectiveness parameter. Unresolved questions in the formulation of the model are the lifespan of parasitized roots and the question whether or not sandalwood will allocate energy resources for maintenance respiration of host roots after the formation of haustoria. The'desk study' reported here was intended to focus subsequent field studies on these unresolved issues

Flora Gunung Kelimutu Dan Gunung Kelibara Taman Nasional Kelimutu, Pulau Flores, Nusa Tenggara Timur [Flora of Mt. Kelimutu and Mt. Kelibara Kelimutu National Park, Flores Island, Lesser Sunda Islands]

Flora of Mt Kelimutu and Mt Kelibara, Kelimutu National Park, Flores, Lesser Sunda Islands had been studied in July-August 2007.About 70 species belongs to 67 families of plants were collected. Vegetation is dominated by Casuarina junghuhniana Eucalyptus urophylla forest and mixed mountain forest composed of e.q. Ficus variegata, Prunus arborea, Actinodaphne glomerata, Litsea resinosa, Celtis tetrandra and Engelhardtia spicata. It is very interesting due it has many endemic species such as Agalmyla elongata, Calamus heteracanthus, Saurauia schmutzii and S. verheijernii those are endemic to Flores island and Rhododendron renschianum which is endemic in the Kelimutu National Park. During the exploration a new species of Begonia kelimutuensis (in preparation) was recorded
