Abstract

ABSTRACTThis research was aimed to evaluate the rates of NPK and calcium fertilizers for the growth of oil palm seedling at main nursery. It was conducted in IPB Experimental Station, Cikabayan, Darmaga, Bogor from December 2011 to November 2012. The two factors, NPK and calcium, were arranged in a randomized block design with three replications. The rates of NPK fertilizer (15-15-15) were 0, 115, 230 and 460 g seedling-1. The rates of calcium fertilizer were 0, 5, 10 and 20 g seedling-1. There was no interaction effect observed between NPK and calcium fertilizer. NPK fertilizer, however had the significant quadratic effect on plant height, leaf number, stem diameter and chlorophyll content. Based on morphology variables, recommended optimum rate of NPK 15-15-15 fertilizer was 333 g seedling-1 for eight months. Thus, NPK rates were 7.00, 7.00, 19.45, 59.25, 66.3, 61.55, 58.97 and 54.16 g seedling-1 from first to eight month respectively. The optimum rate of calcium fertilizer was not determined in this experiment.Keywords: NPK 15-15-15, nutrient, optimum rates, recommendation

Abstract

ABSTRACTDevelopment of Jatropha, an important tropical biofuel crop, to coastal sandy soil is an urgent situation due to more limited of fossil fuel in one side, and high potency of coastal sandy land that has not been utilized yet. Tolerant and sensitive genotypes of Jatropha were treated with drought stress using watering interval, and their responds on the vegetative growth and yield were studied in this reasearch. Drought stress significantly decreased all vegetative growth parameters observed, except the number of branch. Different jatropha genotypes had different number of branch, number of leaf, root surface area, total of root length, root diameter, plant dry weight, shoot root ratio and light absorption. IP-1A genotype had the highest yield, i.e 33.54 g of dry seed plant-1 (equal to 0.15 ton ha-1), in the first year.Keywords: biofuel, sand, watering

Abstract

ABSTRACT      Yield variety of physic nut is one of the factor that cause the gap between the potential and actual yields. In a homogeneous environment, plant yield is controlled by multigenes. To obtain a homogeneous yield, it is necessary to determine the plant characters affecting physic nut yield. A research was carried out in Asembagus and Muktiharjo Research Stations in January-December 2010 to observe plant growth and yield of IP-3A and IP-3M genotypes. Data were analyzed backward stepwise to determine the plant characters that affect plant yield. The results showed that IP-3A plant characters affecting yield from the greatest were the number of branches, the ratio C / N in petiol, the number of non-productive branches, the amount of glucose needed to form per gram petiol tissue, C-organic content in petiol, the ratio C / N in stem, C-organic content in stem, and the amount of glucose needed to form per gram stem tissue. Of the eight characters, only the number of non-productive branches negatively affected on yield, while other characters showed positive influence. The IP-3M plant characters affecting yield from the greatest were the ratio C / N in shoot, N content in shoot, the amount of glucose needed to form per gram shoot and stem tissues, C-organic content in shoot and stem, the amount of glucose needed to form per gram leaf tissue, C-organic content in leaf and water content in stem. Of the nine characters, only the N content in shoot that negatively affected on plant yield, while other characters showed positive influence.Keywords: character, growth, Jatropha curcas, productive branches, yield

Abstract

ABSTRACTThe aims of this research on Reutealis trisperma seed were to know 1) seed harvest maturity level based on physiological and biochemical changes; and 2) seed recalcitrancy based on critical moisture content and storability in two storage temperatures. The research was conducted at Leuwikopo Seed Science and Technology Laboratory, from February 2012 to January 2013. There were three experiments, i.e. I. Effect of seed maturity level on seed viability and vigor (randomized completely block design, 3 seed maturity level, 3 replications); II. Determination of seed critical moisture content, used two methods, i.e. 1) fan drying and 2) air drying (completely randomized design in each drying methods, 3 replications); III. Effect of temperature and period of storage on seed viability and vigor (nested design, first factor was 2 storage temperature and the second factor was 7 storage periods, 3 replications). The result showed that seed physiological maturity achieved in 28 weeks after flowering with morphological criteria were brownish fruit, soft fruit exocarp, brown seed testa; physiological criteria was germination percentage 76-80% and biochemical criteria was carotenoid content 0.62 µmol(g FW)-1. Carotenoid content can be used as biochemical indicator to determine fruit maturity and significantly correlated with moisture content, seed dry weight and germination percentage. Critical moisture content were 8.2-10.9%. These data suggested that seeds could be classified as intermediate. R. trisperma  seeds could be stored for three weeks in temperature 19-28 oC and RH 50-70%, with 12% moisture content used polypropilen plastic bag Keywords: carotenoid, critical moisture content, desiccation, Reutealis trisperma

Abstract

ABSTRACT Melastoma malabathricum L. is an Al-accumulating plant that grows well in acidic soils with high level of soluble aluminum in the tropics. One of the important proteins in the detoxifying Al stress is a plasma membrane H+-ATPase, a most abundant protein on the plasma membrane, encoded by PMA gene. The objective of this research was to isolate and characterize the gene encoding plasma membrane H+-ATPase from M. malabathricum L. Full length cDNA of MmPMA had been successfully isolated through a gradual isolation of the gene. The 5’ end and middle part of the MmPMA gene had been successfully isolated by PCR by using total cDNA as template and pma primers designed from some plants, while the 3’ end of Mmpma had been isolated by 3’ RACE. The parts of the gene had been successfully joined by PCR. The joining product was successfully inserted into pGEM-T Easy and the recombinant plasmid was successfully introduced into E. coli DH5α. Nucleotide sequence analysis showed that the length of MmPMA coding sequence was 2,871 bp encoding 956 amino acids with molecular weight of 105.29 kDa and a predicted pI value of 6.84. Local alignment analysis based on nucleotide of mRNA showed that MmPMA is 82% identical to pma Vitis vinifera; 81% to pma Juglans regia, pma Populus trichocarpa, pma Sesbania rostrata, and pma Prunus persica and 80% to pma Lycopersicon esculentum. Based on deduced amino acid sequence, MmPMA is 94% identical to PMA Vitis vinifera and PMA Juglans regia; 93% to PMA Populus trichocarpa; 92% to PMA Vicia faba, Lycopersicon esculentum, and Arabidopsis thaliana, AHA4. MmPMA has 10 transmembrane domains, 4 cytoplasm loops, 6 functional domains and 3 autoregulatory domains.Keywords: aluminum, cDNA, MmPMA, PCR, RACE

Abstract

ABSTRACTThe major constraint of rice cultivation in the flood-prone area is the lack of tolerant varieties. A rapid screening method have to be developed under controlled environments, such as a green house, to improve the effectiveness and efficiency of the selection under submergence condition. The aim of this research was to study the correlation beetween selection methods in greenhouse and in the field. This experiment was conducted at a green house of Muara Experimental Station, Bogor in 2011/2012. The experimental designs used were randomized complete design for greenhouse experiment and randomized complete block design for field experiment, with three replicates respectively. There were four sub-experiments in the greenhouse experiment, grouped based on seedling age (10 days and 35 days after seeding) and duration of submergence (10 days and 14 days). Those sub-experiments in the green house were compared with the experiment in the field. The results showed that there was strong correlation between recovery percentage in the green house and percentage recovery in the field. The same correlation indeed happen between recovery percentage in the green house to grain yield. Complete submergence at 10-day-old seedlings in green house could be developed as rapid selection method for submergence tolerant rice.Keywords: aciotic stress, correlation, flooding, Oryza sativa

Abstract

ABSTRACTThe availability of nitrogen in soil is one of the limiting factors to support growth and rice productivity. Nitrogen-fixing bacteria have ability to utilize air nitrogen so it becomes available in the soil. The use of nitrogen-fixing bacteria could potentially reduce application of nitrogen fertilizer. The aim of the experiment was to determine the role of nitrogen-fixing bacteria in reducing inorganic N fertilizer on lowland rice. The research was conducted in April-August 2012 at the plastic house of Babakan Sawah Baru Experimental Station, IPB. The experiment was arranged in randomized block design with two factors, namely nitrogen fertilizer and type of bacteria. The dosage of N fertilizer (urea), i.e. 0, 50, 75 and 100 kg N ha-1. The types of bacteria, i.e. without bacteria, Azotobacter-like, Azospirillum-like, and consortium. The result of the experiment showed that N fertilization significantly affected to all variables except the percentage of empty grains per panicle, 1,000 grain weight, and N content of plant. The types of bacteria significantly affected to root dry weight, number of filled grain per panicle, greenness of leaf, uptake and content of nitrogen (shoot and grain), grain weight per plot. Consortium of bacteria were capable to reduce 25% the use of inorganic N fertilizer from recommendation doses (100 kg N ha-1) that based on the value of agronomic effectiveness.Keywords: Azospirillum-like, Azotobacter-like, consortium of bacteria

Abstract

ABSTRACT The objective of this study was to evaluate the effect of seed coating with arbuscular mychorrhizal fungi (AMF) on viability and vigor of soybean seeds during 6 month storage. This study consisted of two experiments conducted at ambient room and air-conditioned room from May through December 2011. The experiments were arranged in  randomized complete block design with two factors. The first factor was seed coating i.e. untreated control and seed coating using AMF while the second factor was storage period i.e. 0, 1, 2, 3, 4, 5, and 6 months. Results of experiments showed that soybean seeds maintained the viability > 88% after 2 months stored in ambient room and >85% after 4 months stored in air-conditioned room. The viability of untreated and coated seeds did not show significant differences in both experiments. Untreated seeds indicated higher vigor either stored in ambient room (index vigor) or in air-conditoned  room (speed of germination). Seeds coated with AMF showed the rate of increase in moisture content slower than the untreated ones during 6 month storage in ambient room. After 6 month storage in air-conditioned room, the coated seeds had lower moisture content than the untreated. The viability of AMF spores coated on seeds was maintained during 6 month storage in both experiments.Keyword: seed storage, storage room, storage period, viability, vigor

Abstract

ABSTRACTMutualism symbiosis between B. japonicum and soybean root is a complex case and managed by molecular signal exchange. Genistein is one of the main isoflavones in soybean root exudates which is responsive to nod gen induction in B. japonicum. Drought stress could give negative effect on the symbiosis. The aim of the research was to study the role of B. japonicum induced by genistein on production and physiological characters of soybean under drought stress. The experiment was conducted in a green house, Faculty of Agriculture, University of Sumatera Utara, using a randomized complete block design with three factors. The first factor was genistein induction, consisted of  with and without genistein. The second factor  was B. japonicum inoculation consisted of  without B. japonicum,  isolate 1, isolate 2 and isolate 3. The third factor  was soil water content condition, consisted of 40%, 60% and 80% of field capacity. The parameters observed were shoot dry weight, root dry weight,  net assimilation rate, dry weight per plant, 50 seeds weight and proline content. The result showed that increasing drought stress conditions decreased shoot dry weight, root dry weight, net assimilation rate, effective nodules number, seeds dry weight per plant and 50 seeds weight. The result showed that as an inducer of B. japonicum in drought stress condition, genistein reduced the effects of water stress on root nodulation of soybean. Proline acts as osmoregulator for increasing tolerance to drought stress in plants.Keywords: drought, genistein, soybean, root nodulation

Abstract

ABSTRACT Iles-iles (Amorphophallus muelleri Blume) produces apomictic seeds lead to low genetic variation. In order to induce genetic variation, germinated seeds were exposed to Gamma irradiation (Co-60) at doses of 10 to 100 Gy. Seed irradiation was conducted at Center for the Application of Isotope and Irradiation Technology -National Nuclear Energy Agency (CAIRT), Indonesia. Morphology and yield of M1 generation were observed. Results showed that irradiation at a dose of 10 Gy close to LD50 with survival rate 56%. Gamma irradiation at a dose of 10 Gy delayed seeds germination.  Germination rates gradually increased and reached maximum at 4 weeks after planting (WAP) for control plants, and 14 WAP of irradiated plants. At 16 WAP, germination rate of 10 Gy irradiated plants was 56% and 84% for those of control plants. Irradiation induced chimera as indicated by short petiole, variegated and abnornal shape of leaflets. Some irradiated plants entered dormancy at 8-10 weeks later than control ones. Prolong vegetative periode lead the plants to produce heavier corms. This study revealed the possibility to induce variation of A. muelleri by using gamma irradition. Keywords: Amorphophallus muelleri, gamma irradiation (Co-60), morphological variation, mutation breeding
