Abstract

Influence of Gamma Rays Irradiation on First Generation (M1) to Obtain New Promising Drought-Tolerance Soybean Genotype. Breeding to produce drought tolerant varieties is one of main strategies in the soybean production improvement. Some limitations in soybean conventional breeding are that it takes long time and that drought tolerant characters are rarely found. Therefore, the improvement of genetic variability is very important to assist drought tolerant. Mutation through gamma irradiation is one of techniques to improve genetic variability. The aims of this research were to obtain LD50, study the influence of irradiation, and genetic of mutation. To determine the LD50, seeds of soybean cv. Anjasmoro were irradiated with 0-800 Gy (100 interval) gamma rays. LD50 was calculated to be 202.5 Gy base on germination rate. Therefore, in further experiment 200-400 Gy (50 interval) dosage were used to irradiate seeds of soybean cv. Anjasmoro and Burangrang. All irradiation dosages (200-400 Gy) damage protoplast, decrease plant survival, prolong flowering dan harvest time, decrease plant height, number of total and filled pod, number of seeds, and improve the number of empty pod.

Abstract

The Effects of Variety and Weeding Times on Growth and Yield of Mungbean (PhaseolusRadiatus L.)The mungbean have a great potential as a food ingredient mixture of refined productsand has certain competitive advantages over other types of beans. Mungbean production in East Timoris still low and has not been able to meet the needs of the market. Therefore, weed control and selectionof good varieties of mung beans is one of the determining factors in the increased production of mungbean.The objective of the study was to determine the effect of time of weeding on the growth and yield ofseveral varieties of mungbean. The study was conducted at the Pilot Suco Hera Sub-distrito Cristo Rei,Dili-Timor Leste. It used a randomized block design with two factors. The first factor was type ofvarieties of mungbean and the second factor was the weeding time. Factor of types of varieties consistedof three, namely: VL = Local Variety, VM = Merak variety, VG = Gelatik variety, while factor ofweeding times consists of PO = No weeding, P1 = weeding at 2 and 4 weeks after planting, P2 =weeding at 3 and 5 weeks after planting, with three replications. The results showed that weeding timeaffected the outcome of drying seed dry weight per hectare. Weeding time at 2 and 4 weeks afterplanting had a better dry weight of seed i.e 1.09 g, compared to those of weeding at 3 and 5 weeksafter planting. The use of different varieties showed that Merak variety had drying seed dry weight of1.16 tons ha-1, Gelatik variety was 1.09 tons ha-1, and the local variety was 0.97 tons ha-1.

Abstract

Potential of Pseudomonas aeruginosa as Biological Control Agents against Sclerotium rolfsii Sacc. and Biological Stimulants on Soybean Plant. The objectives of this experiment were conducted to evaluate the effectiveness ofP. aeruginosa as an agent of biological control and biological stimulants. P. aeruginosawere tested for antagonistic activity against Sclerotium rolfsii Sacc. The test for antagonistic activity by bacteria was done through side by side culture. Soybean seeds that will be used in the rhizobacteria treatment were soaked in rhizobacteria suspension for 15 minutes. For wihout the treatment, seeds soaked with sterile water instead of rhizobacteria suspension. Results of this experiment,P. aeruginosa showed strong inhibitory activity againstS. rolfsii Sacc. on PDA medium. Percentage of inhibitory activity was 94,4%. Application of P. aeruginosa significantly increased the plant growth. The maximum plant hight, the maximum number of leaves, fresh and dry weights of root, fresh and dry weights of shoot, and chlorophyll content on treated plants significantly higher than those of un-treated control plants according to the Duncan’s multiple range test (P<0.05%). These results suggested that application of rhizobacteria could promote the plant growth and increase the yield.

Abstract

In Planta Transformation of SoSPS1 Gene Through Agrobacterium tumefaciens in Balinese Grapevine (Vitis Vinifera L. var. Alphonso Lavalle). Vitis vinifera L. var. Alphonso Lavalle is one of the cultivar of grapevine cultivated in Bali. The sour taste of fruit is one of the problem of these cultivar that make it is less prefer by consumer. Research regarding improvement of fruit quality through genetic engineering has been investigated. The aims of the research were to find out the most proper methods of in planta transformation mediated with Agrobacterium tumefaciens applied on V. vinifera. The T-DNA harbored the SoSPS1 gene under the control of promoter of the CaMV from Cauliflower Mosaic Virus and contained the NPTII gene, a kanamycin resistant gene as a selectable marker for transformant selection. V. vinifera seedlings from stem cutting aged 40-50 days were ripped and then dipped with the bacterial suspension for 1 hour, 2 hours, 1 day, and 2 days. Visualization of V. vinifera samples after PCR showed that ripping and dipping for 2 hours method was positively integrated with NPTII gene. The dipping of plants wound for 2 hours treatment was effective for inserting gene of interest in ripping and dipping methods.
