Abstract

Di Indonesia ada dua marga polong-polongan yang dimanfaatkan bijinya untuk makanan manusia. Kedua marga tersebut adalah Parkia dan Pithecellebium. Dari tiga Jenis Parkia yang dilaporkan tumbuh di Jawa, P. speciosa merupakan petai yang limum diperjualbelikan.Menurut Backer & Bakhuizen van den Brink (1963), petai menyilang secara alami dengan kedawung (P. roxburghiij dan bastar alaminya adalah P. intermedia.Dari segi morfologi, petai dan kedawung mud&h dibedakan, baik dari segi perawakan pohon maupun sifat-sifat polongnya.Dengan demikian adanya bastar antara kedua jenis yang berbeda sifatnya ini akan dapat dikenali dengan mudah pula.Meskipun petai sudah lama dibudidayakan dan dimanfaatkan, keanekaragaman yang ada pada petai ini belum diungkapkan.Memang benar Backer & Bakhuizen van den Brink (1963) menyebutkan bahwa dua macam P.intermedia menyerupai petai sifat-sifatnya, tetapi secara jelas tidak disinggung sifat-sifat yang berbeda pada contoh-contoh petai sendiri.Berbicara mengenai keanekaragaman petai, pada akhir bulan Mei 1979 dari pasar besar Padang dikumpulkan contoh-contoh petai yang dijual di sana. Keanekaragaman polong dan biji dibahas.Demikian juga kadar protein bijinya.

Abstract

Anabas testudineus Bloch, 1792 is economically important fish species found in Lubuk Lampam floodplains of Musi River. Fishing activities that take place throughout the year can affect reproduction patterns and recruitment (new additions) of fish. This study aims to evaluate several parameters of betok fish populations that can be used as input for fish resource management policies in floodplains of Musi river. A total of 3271 samples of betok fish caught by fishermen from March to November 2011 were collected to obtain data on fish length and weight. Growth parameters (L∞, K, Z dan M) were calculated using FiSAT II based on the length frequency distribution of fish. The values of L∞ and K were obtained at 204.75 mm and 0.24 / year respectively while the maximum age of fish was estimated to be 4.36 years. The total mortality (Z) and natural mortality (M) of betok fish is 0.99 / year and 0.42 / year, Fishing mortality (0.56/year). The exploitation rate (0.57) was slightly lower than the predicted value (Emax= 0.69) indicating that Anabas  testudineus was near fully exploited in the Lubuk Lampam floodplain ecosystem.

Abstract

The development of seedless tomato fruits will be more attractive to consumers and industry. Artificial parthenocarpy can be induced through genetic crossing, hormone application or genetic engineering. Development of parthenocarpic tomatos has been done by inserting parthenocarpy gene, DefH9-iaaM into tomato genome via Agrobacterium tumefaciens. Sixty putative transgenic tomato lines were produced, and three events (lines) have been selected as the best event, i.e. OvR1#14-4, OvM2#10-1, OvM2#6-2. These lines contained the DefH9-iaaM based on PCR test. This research aimed was to determine the insertion patern of DefH9-iaaM gene in the progeny of transgenic tomatos lines. Parent variety Oval and line Cl 6046 were used as control plants. Results indicated that tomatos line OvR1#14-4 was still contained the inserted DefH9-iaaM gene and followed the Mendelian pattern (3:1) based on molecular analyses and Chi-square test results, while the others were not identified. Line OvR1#14-4 was required to be further evaluated for phenotypic and genotypic analyses for the expression of their parthenocarpy.

Abstract

The production of good quality seed for culture purpose begins with proper attention to the nutritional requirements of the parental broodstock. The objective of this research was to know the level of lipid in broodstock feed to reach good seed production.The experiment was conducted in concrete ponds located at Research Instalation for Aquaculture Environment and Toxicology,Cibalagung, Bogor. Broodstock with average individual body weight of 420.8 ± 72.10 g were cultured in concrete pond 3.5 x 2.53x 0.8 m with stocking density of 15 fish/pond. Pelleted fish with 35% protein content and different lipid level of 4, 6, 8, 10, and 12 % were given with daily ratio 2 % of body weight. Gonadosomatic index, ovosomatic index; the weight, the number and the diameter of egg; fertilization rate, hatching rate, percentage of larva produced and daily growth rate and survival rate of 21 days old seed were observed. The result showed that there were no significant difference (P>0.05) among treatments for all parameters except for the diameter of the egg. The result showed that all of the broodstock were matured in three months.Gonadosomatic index were ranged between 13.69-16.65%, ovosomatic index: 11.26-14.62%. The weight of the egg varied from 1.45-1.69 mg/egg with the diameter in between 1.37-1.66 mm. The number of eggs per kg broodstock varied from 74,473-88,787 with fertilization rate of : 67.15-93.29%, and hatching rate were ranged from 88.33%-96.62%. The feed with 8% lipid level showed the highest value of gonadosomatic index (16.65%), fertilization rate (93.29%), percentage of larva produced (90.14%), egg weight (1.69 mg) and egg diameter (1.66 mm). Average daily growth rate of the 21 days old offsprings was 18.12%-19.25% with survival rate of 60.25%-75.50%. The feed with 8% lipid level tends to give the best effect on the reproduction parameters and the performances of the seed.

Abstract

Wild rice species are important gene sources for the rice improvement programs.The morphological characters is the easiest way to identify the crop specificity, and it is applicable for determining the relation among species.The grouping on wild rice species are determined by using cluster analysis through the principal component analysis which involved 16 characters of quantitative traits of wild rice species. The total sample of wild rice species was 89 accessions of 18 species.The research was done at green house level during 3 seasons from 2004 to 2005.All the accessions of wild rice were planted in pots consists of 10 kg soil by 3 replications for each accession.The result of analysis of the first principal component from quantitative characters (plant height,amount of grain fill per panicle, amount of grain total per panicle, panicle length, 1000 grains weight, grain shape, days of flowering, total internodes and awning length ) could explain that variability were 82 %.The result of cluster analysis involved the four of principal component with similarity level equal to 80 %, obtained 5 groups of wild rice species. The result of the clusters was Oryza sativa included at cluster I, while O. officinalis had 3 clusters that is cluster III, IV and V. While O. meyeriana and Oryza ridleyi joint at cluster II.Quantitative character was applicable for clustering the accessions of wild rice species as according to each genome.

Abstract

Research on the diversity of snails in Enggano, Central Bengkulu was held on 16 April 2015 to 5 May 2015 by taking three sampling sites that are north-western part of Enggano (Kampung Bendung at Desa Banjarsari and Desa Meok), the centralpart of Enggano (Desa  Malakoni) and the south-easternpart of Enggano (Desa Kaana). Sampling was conducted using purposive sampling while the analysis using graphical method and statistical cluster and t-test. This study found 722 specimens of snails which consists of 24 species from 17 families. Most of the snails found are in small size. Land snails in the forest dominates the north-easternpart as much as 88.2%. compared to  freshwater snails (11.8%). Terrestrial and freshwater snails share amount 50% each in the forest of the central, while terrestrial snails still dominate in the forest of south-eastern part (land snails: snail freshwater = 71.4%: 28.6% ). The existence of land snails and freshwater can not be separated from the state forests themselves besides the condition of the soil and surface water as a result of the topography of the island
