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

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

ABSTRACTPhysiological quality of soybean seeds was easily deteriorated during storage. The objectives of the research were to determine controlled deterioration test which could be used to evaluate soybean seed viability and to find the appropriate controlled deterioration test for estimating storability of soybean seed. The research was conducted at the quality control laboratory PT. BISI International, Tbk., Kediri since October 2012 until February 2013. The completely randomized design with four replications was used in the experiment by moisture content and deterioration periods as treatment. The results showed that the controlled deterioration periods to evaluate two varieties of soybean seed were same for 16 hours at 17.5% moisture content for Wilis and 15% moisture content for Detam-1. The result also showed that there were significant correlations between controlled deterioration values with actual values from 16 weeks storage periods, indicating controlled deterioration test periods could estimate storage periods. Verification of seed vigor relation to storability model showed there were no significant differences between germination and speed of germination between controlled deterioration and actual values. Simulation of soybean seed storability model with germination percentage after controlled deterioration as input variables could predict the storage periods.Keywords: Glycine max, rapid ageing, seed modelling, seed vigour, vigour index

Abstract

ABSTRACTBasil (Ocimum basilicum L.) is cultivated in many countries as vegetable crop, and as herbal medicine or pesticide for mosquito larvae, but there is limited information on its seed viability. Three experiments were conducted at Seed Science and Technology Laboratory Departement of Agronomy and Horticulture IPB from January to June 2011. Experiment one tested viability of basil seeds with different maturation obtained from different fruit maturity and drying treatment. Experiment two stored basil seed for 12 weeks in ambient condition and tested seed viability weekly. In experiment three, two seed lots that have been stored for 2 and 14 weeks in ambient condition were invigorated with GA3 1,000 ppm and KH2PO4 1.5% and light treatment 820 lux m-2. It was revealed that basil seed was physiologically mature at 44-49 days after flowering with 12.5% moisture content and low viability of 34.0%. After-ripening period of basil seed was two week where the seed viabilty increase to 56.7%. Seed viability did not significantly change during 12 weeks stored in ambient condition. Maximum viability of basil seed (64.34-66.52%) could be achieved by invigoration treatment  with GA3 1,000 ppm and light treatment 820 lux m-2.Keywords: dormancy, germination, seed maturity, vegetable crop

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

ABSTRACTThe objectives of this study were to evaluate several chili pepper hybrids whith high yielding character and stable at six environments based on some non-parametric stability analyses, and to study the correlation among the stability of non-parametric methods. The hybrid of chili pepper (7 candidates varieties and 5 commercial hybrid cultivars) were grown in a randomized complete block design with 3 replications in 6 different environments. Ten nonparametric stability methods were used to identify the stable genotypes.  According to the SI(3), RS, NPi(1), NPi(2), NPi(3) and NPi(4) stability parameters, Imperial was the most stable hybrid. According to the SI(1), SI(2) and TOP  stability parameters and yield, IPB CH3 was the most stable hybrid.  In this study, the high TOP values were associated with the yield. Nonetheless, the results of the other non parametric (SI(6), NPi(3) and NPi(4)) were negatively correlated to the yield. The results also revealed that based on the non parametric stability test, the results could be classified into 2 groups, according to the agronomic and biological stabilities. Keywords: chili pepper, environment, non-parametric stability, yield

Abstract

ABSTRACTThe research objectives were to evaluate biological agent treatments in controlling bacterial leaf blight (BLB) and increasing plant growth and seed production of rice. The experiment was conducted in the greenhouse and field using the same experimental design (randomized block design with two factors) and three replications. The first factor was seed treatments, i.e. negative control, positive control, streptomycin sulphate 0.2%, Pseudomonas diminuta + Bacillus subtilis, matriconditioning + streptomycin sulphate 0.2%, and matriconditioning + P. diminuta + B. subtilis. Spraying plants (second factor): untreated control, streptomycin sulphate 0.2%, biological agent F112, biological agent F198, and biological agent F57. In the greenhouse, matriconditioning + P. diminuta + B. subtilis  improved seed germination, plant height, and plant dry weight. Spraying plants with biological agent F112 increased plant dry weight. Meanwhile, matriconditioning + P. diminuta + B. subtilis followed by spraying plants with biological agent F112 reduced the BLB severity. In the field, matriconditioning + P. diminuta + B. subtilis improved seedling dry weight. Matriconditioning + P. diminuta + B. subtilis and spraying plants with biological agents F112 controlled BLB and increased plant growth. However, all treatments were not able to increase healthy seed production.Keywords: matriconditioning, seed treatment, phyllosphere biological agents, Xanthomonas oryzae pv. oryzae
