Abstrak: Mangosteen reproduces trough apomixes mechanism, from which the seed develops without fertilization. Mangosteen is an obligate apomicts and it is believed that all of its progenies may have the same genotype as their mother plant. However it was found that genetic variations occurred among mangosteen accessions. This research is aimed to study pattern of morphology variations, genetic consistency among generations and genetic variations in single plant. The study was carried out at Center for Tropical Fruit Studies (PKBT) during February – September 2009. The plant materials used four generations (P1, P2, P3, and P4) of mangosteen were taken from Wanayasa, Purwakarta according to tree height and sector (north, east, west, and west). There are three analysis: morphology, molecular by ISSR, and data. Genetic observations were conducted by using Inter Simple Sequence Repeat (ISSR) technique. Ten primers were used to amplify the genomic DNA of mangosteen. The levels of polymorphism as revealed ISSR were 70.21%. It was found that genetic and morphology variations occurred among tree of different age. Morphology variations was bigger than genetic variations among mother plant. Genetic variation also was occurred within single plant, among progenies, and between progeni and mother plant. This information may be useful to determine of optimum age of mangosteen for becoming mother plant.

Abstrak: Mangosteen population has been reported performed apomixis reproduction, lead to assumption genetically homogen. Early studies showed that there were variation among mangosteen population. However the variation could be originated from environment variation. To elucidate genetic variability among mongosteen population in more detail seedling from Purworejo, Purwakarta, Leuwiliang and Trenggalek where grew at same environment in Bogor. The objective of this study is to analysis variability among mangosteen population from Purworejo, Purwakarta, Leuwiliang and Trenggalek. The studies was carried out in the origin of population for morphological character and at Bogor for seedling performance since February 2003 to July 2003. The plant material for this study were ten parent trees from each production centre and ten fruits from each trees, subsequently their seed used for seedling at Bogor. Obtained data analyzed by using homogenity of variance test (Bartlet test) and was continued with Tukey's Studentized Range Test. The plants in seedling were arranged in Completely Randomized Design consisted of four treatment with 10 replications. The result of this study was showed the homogenity variance in leaf weight, leaf area indeks, leaf length, leaf width, fruit weight, seed weight, number of seed. In seedling all character that observed had homogen variance. The analysis of mean morphological character showed that Trenggalek might had the best condition for mangosteen growth. Plant from Trenggalek showed the highest mean in leaf length, leaf width, plant height and number of leaf. All character that observed in seedling had high heritability. Comparison with other study in 2002 and 2001 showed that population had the same result in homogenity variance, was performed that leaf area index, leaf length, leaf width, plant height and number of leaf had homogen variance. It showed that mangosteen population probably had a stable response to enviromental influence

Judul: Infeksi Virus Parainfluenza Pada Anjing
Abstrak: Virus parainfluenza anjing termasuk famili Paramyxoviridae, berbentuk pleomorf dengan ukuran bervariasi (bergaris tengah antara 100-500 nm), berpembungkus peka ether, berisi genom RNA dan secara serologis mempunyai kesamaan dengan virus SV-5 kera; dikenak sebagai salah satu kausa penting dari sindrom "kennel cough". Infeksinya dapat mengenai anjing semua umur yang belum pernah terinfeksi atau mendapatkan vaksinasi mengakibatkan gejala klinis ringan yang terbatas pada traktus respirasi atu infeksi yang secara klinis tidak memperlihatkan gejala nyata. Gejala klinis yang nampak setelah masa inkubasi (1-5 hari) terlewati berupa batuk yang tidak berat selama beberapa hari, berbagai tingkat tonsilitis dan pharyngitis dan kadang-kadang ditemukan kenaikan temperatur rektal antara 1-2 derajat C dari temperatur normal rat-rata. Anjing terinfeksi mengandung virus pada traktus respirasi bagian atas dan bawah serta limfonoduli sampai hari ke 9 setelah infeksi. Penyebaran virus antar anjing terjadi secara aerogen.
