Abstract

H. IMAMUDDIN. 1987.The failure of pods and seeds development of Bauhinia tomentosa L. Suppl. Berita Biologi 3 : 35 - 37.Microscopic,observation to study the failure of pods and seeds development of Bauhinia tomentosa L. was conducted.Several buds,6 - 21 mm long, were diserved with paraffin method.The results showed that the failure of pods and seeds development of B. tomentosa were not caused by either flower morphology, pollen fertility or nticrospore development,but by abnormal development of saccus embrionalis,followed by incomplete development of egg cell,which made the flowers aborted before receptive.

Abstract

The experiment was conducted to evaluate the growth of Pangasius djambal which were fed with different dietary protein levels.Fifteen fingerlings averaging 6.13 g individual body weight were stocked in each of 9 fibreglass tanks filled with 30 liters of water.They were fed daily for 42 days with diets containing 30%, 35% and 40 % protein. The feed was given in crumbled form at 7% of total biomass,4 times a day and contains 2600 k.cal.DE/kg feed.The result showed that feeds with different protein content gave qudratic respon curve. Maximum values for protein retention (36.65%) were obtained with feed containing 34.14 % protein.The feed with 35% protein content gave the lowest (78.12%) lipid retention. Feed conversion ratio (1.31-1.36), daily growth rate(3.64-3.82%) and protein efficiency ratio (2.05 - 2.29) were not different among treatments.The survival rates 100% were the same for all treatments.It is suggested that feed with protein content 35% and 2600 K. cal DE/ kg feed can be used in intensive culture of Pangasius djambal fingerlings to attain the best growth and suvival rate.

Abstract

A baby boy was born in Rashult, Smoland, Sweden, on 23 May 1707, who later became the world famous Swedish botanist and deservedly be called The World's Father of Taxonomy. The baby was baptized as Carl Linnaeus. According to Swedish customs at that time, the baby should had been named Carl Nilsson (Carl, son of Nils), since his father's name was Nils Ingemarsson (Nils,son of Ingemar Bengtson).When Nils Ingemarsson was enrolling the University of Lund, he had - based on the university rules- to have a family name. He choosed Linnaeus as his family name, and since then Nils Ingermarsson was known as Nils Linnaeus.Carl Linnaeus (hereafter Linnaeus) finished his primary school and Gymansium at Vaxyo. After graduation from the Gymnasium,Linnaeus was trained as dress- and shoemaker before pursuing medical studies at the University of Lund in 1727.A year later he moved to the University of Uppsala. Linnaeus got his medical doctorate from the University of Harderwijk (Holland) on 23 June 1735. Before returning to Sweden, Linnaeus was working and visiting several places. He had the opportunity to meet many outstanding botanists during his visits. When he was working (1735-1737) at "Hartekamp", Leiden, and Amsterdam he published many more new findings compared to those other scientists during that time. Linnaeus returned to Sweden and married Sara Lisa Morea on 26 June 1737. They have seven children (two sons and five daughters). Linnaeus was appointed as Professor at the University of Uppsala in 1739 and in 1757 he was ennobled by the King of Sweden. In 1763, Linnaeus' health was declining. In the same year Carl Linnaeus, Jr. became Professor at the University of Uppsala replacing his father. Linnaeus died on 10 January 1778 and five years later, Carl Linnaeus, Jr. died on 1 November 1783. Carl Linnaeus, Jr. was buried in his father's grave in the Katedral of Uppsala. Sara Lisa Morea, Linnaeus' wife, sold the valuable Linnaeus' collection to Sir Edward Smith for 1,000 guinea in 1784. Sir Edward Smith, the First President of The Linnaean Society of London, died on 17 March 1828. There after, The Linnaean Society of London, bought the entire Smith's collection for 3,150. The Linnaeus' collection is now housed safely in Burlington House, Picadilly, London.

Abstract

Kecondang or Taka (Tacca leontopetaloides), a member of Taccaceae, is one the carbohydrate alternatives to rice which can be developed in coastal area. With the global warming, the sea level has increased and small islands are more isolated. The people who lives in these islands should depend on their bioresources.As Taka inhabits coastal area, the development of this plant becomes critical.A total of 65 accessions of Taka from 9 provenances in Indonesia (Sukabumi, Madura, Kp.Siung (Yogyakarta), Gn. Kidung (Yogyakarta), and the small islands in Karimun Jawa namely Nyamuk, Katang, Cendekia, Kumbang, Seruni islands) were characterized using six ISSR markers [GSGG (TG5)T; CCAG(TGG)3TG; GGAG(TGG)3TG; BDBT(TCC4); (AC)8C; (AG)8G]. The scoring of the fragments resulted in 55 (69.6%) polymorphic bands. The size of the bands varied from 150bp to 1,6kb. The 65 accessions of Taka made several clusters according to their provenances. The range of individual genetic dissimilarity was from 0.012 to 0.186. The results showed that amongst nine population studied, Gn. Kidul, Yogyakarta population has the highest level of genetic variation with mean values of Na = 1.3544±0.4814, Ne =1.1784±0.3025, PLP = 35.44% and He = 0.1094±0.1681. Whereas, P. Nyamuk, Kep. Karimun Jawa population has the lowest level of genetic variation with mean values of Na = 1.0759±0.2666, Ne = 1.0523±0.2163, PLP = 7.59% and He = 0.0275±0.1097.

Abstract

Research was aimed at knowing the effect of increasing ammonium concentrations on Meloidogyne javanica development in tomato roots growing in axenic culture.Egg masses of M. javanica were exposed to deficient ammonium concentration (1.5 ppm NH/) in a nutrient agar medium upon which tomato roots were growing. One week after inoculation, stages of nematode development were recorded and infected tomato roots were aseptically transferred into nutrient agar media with four different ammonium concentrations (1.5. 9.0. 54 and 324 ppm NH/). Stages of nematode development inside roots were then observed at weekly interval for three weeks. Results of the research showed that increasing ammonium concentration after root infection suppressed nematode development. In roots transferred to high ammonium concentrations, fewer nematodes matured and most of those that did were males. In addition, there were also fewer galls and lower root dry weights in increased ammonium than those with constant low ammonium concentration.

Abstract

The feeding rate and the feeding frequency influencing the growth and survival rate of fish. The objective of this research was to know the proper level of feeding frequency for supporting the growth of patin pasupati (hybride between Pangasius hyphophthalmus and P. djambal).The experiment was conducted in fibre glass tanks located at Research Instalation for Genetic and Freshwater Aquaculture Technology, Sukamandi. Patin pasupati fingerling with average body weight of 2.23 ± 0.48 g were stocked in 9 fibre glass tanks, each filled with 30 litres of water.The experimental design was Completely Randomized Design with 3 treatments and 3 replications. The treatments were feeding frequency as follows 1, 3 and 5 times per day. The feeding rate was 8% of total body weight per day.The parameters were specific growth rate, average body weight gain, feed conversion ratio, protein retention,lipid retention, protein efficiency ratio and survival rate. The results of experiment indicated that there were significant different(P<0.05) among treatments for specific growth rate, individual body weight gain, feed convertion ratio,protein retention, lipid retention and protein efficiency ratio.The highest value for specific growth rate (7.03%) and protein retention (54.59%) were found for feeding frequency 5 times per day.The values of feed conversion ratio and survival rate for feeding frequency 5 times per day were 0.83 and 100%, respectively.

Abstract

Wild species of begonia existed in remnant forest of Cibodas Botanic Gardens, but their diversity, distribution and ecological preference were not much known. Data of condition and habitat characteristic of wild begonia are important in their cultivation. The aims of this study are to inventory the diversity of wild begonias and their distribution habitat preference in remnant forest of Cibodas Botanic Gardens. Sample were collected from four remnant forest using exploration method. Analysis of vegetation where wild Begonia existed was conducted using 1x1 m plot in around every individu of Begonia found. The principle component analysis (PCA) was carried out using R program version 2.11.0. The result showed that 50% of the mountain Begonia in West Java can be found in remnat forest area. The light intencity, soil humidity and air humidity were highly correlated to distribution of wild Begonia. The microclimate conditions in remnant forest area are appropriate with habitat of Begonia.
