Abstract

Tailing from mining activity contains heavy metal that can be managed by phytoremediation. Plant selection to be used in phytoremediation plays important role that determine the success of these activities. The objective of this research is to study the growth of four forest tree species in media containing tailings from gold mining. Four fast growing tree species, i.e. Swietenia macrophylla King., Anthocephalus macrophyllus (Roxb.) Havil., Maesopsis eminii Engl., and Toona sureni (Blume) Merr., and two kinds of growing media, i.e. tailings and mixture of tailings + compost with 3:1 ratio, were used in a Completely Randomized Factorial Design. The growth parameters measured were plant height and diameter, leaf length and width, number of leaves, stomata density, total wet and dry biomass, also root-shoot ratio, and percentage of survival. The results of the research showed that plant types significantly affect all parameters observed. Media treatment had significant effect on total wet and dry biomass only. Interaction between plant types and media gave significant effect only on total wet biomass. Based on survival and growth parameter observed A. macrophyllus gave best performance.Key words: A. macrophyllus, M. eminii, phytoremediation, S. macrophylla, tailings, T. sureni

Abstract

Mutation is a process of change in genetic structure of particular organisme. Genetic changes due to mutation can produce new characteristic and increase genetic diversity, which will be utilized for improvement program. Several artificial mutation programs have proved to produce new superior individual. One common artificial mutation used is gamma radiation. This study aimed to characterize 9 years old gamma irradiated sengon trees, with doses 0, 5, 10, and 15 krad based on its morphological characters, wood density, resistant to diseases. The observed parameters were tree diameter, height, volume, clear bole height, stem straightness, permanent branch, number of branches, canopy length, wood density and resistance to gall rust disease. Average values of all parameters of mutant lines does not differ significantly from control trees, however some individuals have better morphological characters than others. Mutant lines with 5 krad dose have close association with permanent branch and stem straightness, 15 krad dose with volume, diameter, height and crown length, while 10 krad with number of branches. Average wood density of mutant lines did not differ significantly from control either, with highest value belonged to 10 krad dose. Selected superior tree candidates were individuals with number 5.07, K1, 15.27, and 15 NN.Key word: breeding, characterization, mutation, sengon.

Abstract

Deforestation and fragmentation of mangrove forests in Indonesia are widespread that resulted in losing biodiversity including genetic variation. Rhizophora mucronata Lamk. is a common mangrove species in Secanggang, Langkat, North Sumatra and have been degrading due to anthropogenic disturbance. The aim of this study is to determine the genetic variation in natural population of R. mucronata in Secanggang, North Sumatra using isozyme markers. From five enzymes systems used namely aspartate aminotransferase (AAT), alcohol dehydrogenase (ADH), esterase (EST), malate dehydrogenase (MDH), and peroksidase (PER); eleven loci was found and five polymorphic loci were detected.The estimate value of genetic variation parameters i.e. observed and expected heterozygosity, average alel per loci, and average polymorphic (95% criteria) were 0.1386, 0.1724, 1.5455, and 45.45 % respectively.The low genetic variation of R. mucronata found in this study suggested that genetic variation may be influenced by anthropogenic activities such as illegal logging, conversion into shrimp pond and agricultural farm.Keywords: Anthropogenic, genetic variation, isozyme, mangrove, Rhizophora mucronata

Abstract

The study was carried out for investigation of the adaptability of white jabon seedlings from 12 populations to drought and water logging stresses in a controlled green house. The results showed that the adaptive responses of white jabon seedling to drought and waterlogging stresses were affected by genotype (population). The drought and waterlogging stresses significantly inhibited plant growth, biomass accumulation and allocation, leaf area, also decreased chlorophyll content, increased carotenoids contents, and accumulated free proline. Relative water content and specific leaf area tended to be higher in waterlogging and declined in drought stresses.  The result clearly indicated that white jabon seedlings were more adaptive to waterlogging than to drought stresses. Moreover, there were different responses to drought and waterlogging stresses between the twelve populations. Kampar, Gowa, Kuala Kencana and OKI populations exhibited higher growth performance and stress tolerance index to be adapted to waterlogging stress, while Gowa, Pomalaa and Kampar populations had relatively better growth performance in the drought stress.

Abstract

Tracking the origin of Teak timber and its wood product is possible to be carried out using stable isotopes fingerprinting.  To enrich the available variation patterns, Teak woods samples were collected from nine Forest Management Units (FMUs) representing all provinces and Teak centres in Java.  Mills from all part of woods were mixed for analyses.  The mills were burned under vacuum in a reactor system at 1200oC for 2 h, the resulting clean CO2 was transferred to the mass spectrometer to determine its isotopic composition of δ13C and δ18O.  The generated data was then analysed using multivariate analysis.  The results showed that isotopes analysis grouped Teak populations in Java intoWest Java population and mixed Central-East Java population.  To consider wood as material for fingerprinting traded forest product, a refinement on method should be done.

Abstract

The embryogenesis (SE) has important role for genetic engineering of cassava (Manihot esculenta Crantz). However, the success of SE induction depend on plant growth regulator s (PGR)s and treatment enriched in induction media.  This experiment tried to induce callus formation of cassava from several in vitro explants: immature leaf, apical bud, and internode; and to develop somatic embryogenesis of cassava in several media enriched with tyrosine and copper sulphate (CuSO4) added into media enrich with picloram as treatment.  Different response of explants source to callus induction treatment from those three varieties in callus induction as well as friable callus formation were found in this experiment. The best medium to induce varied with variety; MS media supplemented 12 mg/L picloram + 0.5 mg/L CuSO4 was the best for “Adira 4” and  half MS and half GD media supplemented 12 mg/L picloram + 100 mg/L tyrosine for “Malang 6”.  All treatments resulted somatic embryo which developed indirectly and in morphologically normal somatic embryos

Abstract

This experimental research was performed to observe the influence of an agricultural liquid organic fertilizer called Bio Ferti on the growth and biomass of Spirulina platensis, aiming at replacing inorganic fertilizer with the liquid organic one. The cultivation of the microalgae was conducted over seven days at Nogotirto Algae Park. The liquid organic fertilizer, namely Bio Ferti, was obtained from the Faculty of Biology, Universitas Gadjah Mada, and prepared to have doses of 2, 4, 6, 8, and 10 mL. For comparison, an inorganic fertilizer with the same doses was also prepared. The variables to be observed were cell density, dry cell weight, and growth kinetics. The culture medium conditions observed were temperature, pH, and salinity (the optimum salinity was 20 ppt). The growth kinetic analysis was performed mathematically using numerical simulations using the Contois and the Haldane models. This research’s results showed that Bio Ferti affected the growth rate of Spirulina platensis. With a dose of 2 mL, it became the optimum medium which produced the highest density and dry weight of 1.78x106 cells/mL and 160 mg/mL, respectively. Meanwhile, the inorganic fertilizer with a dose of 10 mL produced the highest density and dry weight of 2,13x105 and 80 mg/mL, respectively. The temperature ranged from 28 to 31°C, while the pH ranged from 8.01 to 9.02 for each medium. The suitable model to describe the growth kinetics of Spirulina platensis was the Haldane model.

Abstract

Endophytic fungi have been reported to promote plant growth and resistance to biotic and abiotic stresses. This study aimed to determine the effect of endophytic fungi application isolated from the sengon (Falcataria moluccana) seeds on the growth of sengon. The seed-borne endophytic fungi were applied when the session was three weeks old by sprinkling each suspension of endophytic fungi (103 to 106 spores/ml) on the soil around the plant roots. The experimental parameters evaluated were height, diameter, and total wet and dry weight. This study showed that endophytic fungi treatment has no significant effect on the stem diameter, total wet weight, and water content; but significantly affected the height and total dry weight. Cladophialophora sp. and Ascotricha sp. fungi increased the height growth of sengon, while Aspergillus sp. fungi increased the total dry weight against the control. Ochroconis sp. treatment was not significantly different from the control. The shoot-root ratio values range from 1.13-1.43, indicating that the seeds already have roots supporting plant growth. The Dickson quality index range from 0.65-1.03 suggested that the seedlings have good biomass distribution. Consequently, endophytic fungi have the potential to increase the growth of sengon seedlings. Keywords: endophytic fungi, Falcataria moluccana, seedling growth, sengon
