Abstract

Jali (Coix lacryma-jobi L.; Poaceae) is a potential cereal for food diversification especially as carbohydrate source. The aim of this current research was to study the productivity of jali cultivated under various doses of fertilizer. Jali were planted on polybag (30x40 cm) with mix-ture of soil:compost=2:1 as planting media. Fertilizer treatments were A) 0-0-0; B) 2-1-1; C) 2,5-1,5-1,5; D) 3-2-2-; E) 3,5-2,5-2,5 and F) 4-3-3 gram urea:SP36:KCl (gr/polybag). The experiment used randomized block design with 9 replications. Result indicated that on 13 WAP (Week After Planting) the highest plant height achieved on 2,5-1,5-1,5 treatment (198,44 cm), leaf number on 4-3-3 treatment (65,44), tiller number on 4-3-3- treatment (4,22), and branch number on 2,5-1,5-1,5 treatment (5,89). These measurements were significantly different from control but not with the other fertilization treatments. On harvesting time of 6 MAP ( Months After Planting) the highest number of seed/plant was from treatment 4-3-3 (792,6) followed by treatment 2-1-1 treatment (672,5). The result of this study suggested that 2-1-1 gram Urea:SP36:KCl (gr/polybag) treatment was the best in increasing hanjeli productivity.

Abstract

The research were carried out to study the potency of Salvinia molesta D.S. Mitchell (Kiambang), Limnocharis flava (L.) Buchenau (Genjer) and Monochoria vaginalis (Burm.f.) Presl (Eceng) for Hg phytoextraction on paddy field contaminated with Hg from illegal mining. The plants were grown on contaminated media from paddy field in Pongkor (68.269 ppm Hg) added by NPK fertilizer (0, 3 and 6 g/pot) and ammonium thiosulphate chelating agent (0, 20 ppm). The result showed that the growth of kiambang,eceng, genjer and padi are significantly different. Chelating agent did not significantly affect the plant growth, meanwhile fertilizer significantly affected the plant growth. Thetreatments resulted in different Hg concentration in the plants. Fertilizer increased plant biomass and so plant Hg content since Hg contents is a function of total biomass and Hg concentration. It can be concluded that based on the criteria of accumulator plant,kiambang is the most potentially Hg accumulator followed by genjer and eceng.Key words: Phytoextraction, Hg, Salvinia molesta, Limnocharis flava, Monochoriavaginalis

Abstract

Mercury is one of important contaminants in mine lands. One approach to remediaterisks from this metal pollutant is phytoextraction using hyperaccumulator plants. Theseremarkable plant species accumulate appreciable high concentrations of metals thando normal plants when the normal plants suffer yield reduction from metal phytotoxicity.Some plant species growing in gold mine contaminated areas indicated high toleranceand potentially effective in accumulating mercury in their roots and above groundportions. Salvinia molesta is one of them. This plant could be utilized as hyperaccumulatorfor cleaning up mercury contaminated sites. This research aim to study phytoextractionof mercury by Salvinia molesta and the effectiveness of mercury degradator bacteria onplant tolerance and mercury phytoextraction. In this study Salvinia molesta was grown inmercury contaminated liquid gold mine waste, added with Mercury (II) Chloride (HgCl2)0 ppm Hg, 10 ppm Hg, 30 ppm Hg and 50 ppm Hg. Mercury degradator bacteria wasapplied in the media. The results showed that Salvinia molesta was able to survive evenin media with high level of mercury concentration (50 ppm), although the number ofplant survival tend to decrease with the increase of mercury concentration. Variables ofsurface coverage and live plants decreased with the increase of mercury concentrationin the media. There was a close correlation between plant growth variables and mercuryconcentration in the media. The effects of mercury toxicity on plants seems to decreasein bacteria treated plants. It was indicated by the higher percentage of surface coverageand plant survival in bacteria treated plants than that of untreated plants up to 30 ppm Hg.Recovery from toxicity was shown in bacteria treated plants up to 30 ppm Hg. Mercuryaccumulation in plants tent to increase with the increase of mercury concentration inmedia. It can be concluded that plant performance was better and mercury concentrationdecreased in bacteria treated plants.

Abstract

Contamination of mined soil and water affects not only to agriculture system but alsofood chains and epidemiological problems. As soil metal can not be biodegraded,remediation of soil heavy metal risks has been a difficult and expensive goal. Presentlythere are several different strategies available for the clean up and restoration ofcontaminated soils. One approach to minimize risks from some toxic pollutants isphytoextraction using hyperaccumulator plants, known as phytoremediation. In thisresearch Centrosema pubescens was studied to examine its potency ashyperaccumulator against cyanide. Although cyanide is not categorized as heavymetal, its presence is considered as one of important toxic pollutants in theenvironments. Detoxification of cyanide (CN) contaminated soils and waters withplants seems to be a feasible option. Centrosema pubescens which proven tolerant anddominant in the CN contaminated environment was used in this research. The plantswere grown in tailing waste media added by 0, 10, 20 and 30 ppm CN. Different pHlevels were applied, i.e.+ 6 and +5. The results showed that the plants were capable ofgrowing under high level of CN. The results indicated that Centrosema pubescens canbe considered as high tolerance and potentially effective in accumulating CN, i.e up to3.564 ppm in roots and up to 3.564 ppm in shoot with concentration ratio (shoot/root)up to 1.13. The plants also indicated high tolerance by producing high biomass underhigh level of CN, i.e up to 36.517 g (under 20 ppm CN).

Abstract

Drought Tolerance Assay on Resulted Mutation of Arrowroot Plant (Maranta arundinacea L.) with Gamma Irradiation. Selection of garut (Maranta arundinacea L.) toward drought stress was conducted in induced mutant by using provenance plants from some semi aridregions of East Jawa. In this research three provenance were used 1) Garut from Dusun Pogal, Desa Lebakrejo, Kec. Purwodadi, Kab. Pasuruan (N1); 2) Garut from Dusun Sembung, Desa Parerejo, Kec. Purwodadi, Kab. Pasuruan (N5); 3) Garut from Dusun Genitri, Desa Gunting, Kec. Sukorejo, Kab. Pasuruan (N8). Provenance plants were treated with mutation induction using several levels of gamma radiation i.e. 0, 10, 20 and 40 Gy. The inducted plants were thenplanted in optimum environmental condition for acclimatization. After 5 months the plants were placed in a greenhouse for water stress treatments. Three levels of water regimes 1) optimum water (field capacity Ø = -0,3 to -1,5 Mpa); 2) 7 days watering interval (Ø =-1,0 to -11,0 Mpa); 3) 14 days interval (Ø = -4,0 to -15,0 Mpa). Plant drought tolerance was examined by analyzing morphological and physiological characteristics related to drought tolerant characteristics, including stomatal conductance (stomatal opening), transpiration, rate of CO2 assimilation, biomass production and yield, Harvest Index and drought Tolerance Index. The resultsshowed that radiation treated plants were more capable of maintaining their water potential (Ø). This indicated by significantly higher values of Ø in treated plants i.e. -2.95 Mpa(10 Gy),-2.86 Mpa (20 Gy) and -2.84 Mpa (40 Gy), compared to -3.74 (Untreated plants). Drought stressed plants produced total biomass 79,55 g/plant, much lower compared to unstressed plants (308,20 g/plant). The highest yield was N8 (219,53 g biomass and 139,83 g tuber), followed by N1 (183,32 g biomass and 126,20 g tuber) and N5 (178,8 g biomass and 136,64 g tuber). Drought Tolerance Index of untreated N1 was the highest (1,27), followed by N5 treatedwith 40 Gy (1.22), N1 with 10 Gy (1.17) and N8 with 40 Gy (1.00). Among radiation treatments, untreated plant produced the highest yield followed by the plants treated with 10 Gy, and the lowest was treated with 40 Gy.Keywords: Drought, tolerance, Maranta arundinacea, mutation, gamma, radiation

Abstract

Ease of access, affordability and continuity of katuk production is important to support a variety of supplements industry-katuk based being developed at this time. The problem is the existing clones and its cultivation technique has not been able to fulfil the market needs. Therefore clone assembling was done to produce triploid katuk with larger leaves size. In this paper we put forward the research on the fertilization and pruning time that appropriate to support the leaf production of triploid katuk. The study was carried out at the experimental plot in Botany Division of Research Center for Biology-LIPI. The experimental designs was Nested RCBD Design, the main plot were 2 level of pruning time (P1: 3 Weeks After First Pruning (MSPP) and P2: 5 MSPP). The subplots were fertilization (K: Control, B: Beyonic, B ¼: Beyonic + NPK¼, B ½:  Beyonic+ ½ dose NPK and NPK: NPK without Beyonic). The growth parameters observed were plant height, number of leaves, the leaf size, were done every week until 8 weeks after planting (WAP). The first pruning to harvest shoots were done at 8 WAP, and the next pruning were done according pruning time treatment i.e. P1 and P2. The pruning was done 3 times. The variables observed at pruning time were shoot length, number of leaves, leaf size, the pruned fresh weight and the fresh weight of edible parts. The result indicated that the triploid katuk clones showed a good response to fertilization both growth and leaf production. The biofertilizers can be combined with the use of inorganic fertilizers to increase edible part of pruning harvest production. Keywords: pruning time, bioorganic fertilizer, triploid katuk, pruning harvest production

Abstract

ABSTRACTEffectivity of EDTA (EthylenediaminetetraceticAcid) in Increasing Lead Accumulationof Saccharum spontaneum Grown Under Gold Mine Waste. Lead (Pb) isknown as one of a major metal contaminant in mine tailing. This metal has low solubility,and in many cases, is not readily available. In most soils capable of supporting plantgrow, the soluble Pb2+ levels are relatively low and will not promote substantial uptake bythe plant. In addition, many plants retain Pb2+ in their roots with only minimal trabsportto the aboveground plant portions. Therefore, it is important to find ways to enhance thebioavailability of Pb2+ or to find specific plants that can better translocate the Pb2+ intoharvestable portions for phytoremediation. The success of Pb phytoremediation is tohave significant Pb availability as well as a large quantity of plant biomass with high rateof growth. This experiment was conducted to obtain both purposes. Saccharumspontaneum which proven tolerant and dominant in contaminated area as well as potentialin producing high biomass was used in this research.The plants were grown in wastemedia added by 100 ppm, 200 ppm and 300 ppm of Pb. Ethylenediaminetetracetine Acid(EDTA) was applied to increase Pb availability and plant uptake as well as translocationto the aboveground portions. The results showed that the plant still capable of growingunder the highest level of Pb. EDTA increase Pb availability and plant uptake. Pb accumulationin the aboveground biomass of EDTA treated plants were relatively higher thanuntreated plants.Key words: Timbal, EDTA, phytoremediation
