Abstract

An experiment to test the growth and development of selected legumes, i.e. Peltophorum pterocarpus DC Heyne (soga), Cassia multijuga Rich. (kasia), Cassia surattensi Burm. f. (galenggang) and Caesalpinia pulcherrima Swartz (kembang merak),  on tin tailings was conducted at Tambang Terentang 25, Pangkal Pinang Production Site, Bangka Tin Miningfrom mid March 1989 to January 1990. The four legumes were selected for the facility in obtaining seed, their ability to improve soil fertility, and their ornamental value. The experiment on four legumes on tin tailing, compared to those grown on yellowish brown Podzol association and Bangka podzol, consisted of four parallel trial units based on the randomized block design with three replications. The tests results of 14 weeks of growth indicate the legumes tested, with the exception of Cassia surattensi Burm.f possess an adequate potential to be grown and developed on tin tailing for the improvement of visual quality, vertical and horizontal structure, and ecological function of the lanscape tailing on Bangka Island.

Abstract

This pot experiment was to evaluate the influences of cotyledons detachment at seedling stage on the efficiency of labelled N-urea uptake and proportion of N-fixation by soybean cv. Wilis grown under saturated soil culture. Based on the result of preliminary experiment, cotyledons detachment was held at 7 days after sowing (das). The cotyledons detachment significantly reduced N-urea uptake efficiency and N-fixed proportion. The N-urea uptake efficiency at 21 days, R4, R5, R6, and R8 stages by cotyledons-detached plant were 30.5 %, 24.6 %, 23.7 %, 24.0 %, and 22.45 of the total N assimilated. Those of the cotyledons undetached-plant (control plant), the value were 31.6 %, 24.05, 24.7 %, 2.7 %, and 23.6 % respectively. At R8 stage, the cotyledons-detached plant has the amount of N-fixed proportion of 54.2 and N-soil of 23.4 %, whereas those of the control one had the amount of 49.7 and 26.7 % respectively. N-urea uptake, N-fixed, and N-soil uptake by the cotyledons- detached plant were lower than that of the control one (i.e. 69, 80, and 645 of the control respectively). The cotyledons detachment also result in inferior vegetative and productive growth of the plant in terms of decreased root dry weight (21.1 %), leave dry weight (18.8 %), plant dry weight (26.7 %), pot dry weight (23.8 %), grain number/pot (32.8 %), and grain dry weight (26.9 %). It seems that the lower growth and yield of the cotyledons-detached soybean paint were caused by the lower total N-uptake due to cotyledons detachment.

Abstract

Eleven genotypes of insertional mutant Nipponbare rice carrying randomly inserted activation tag were tested to investigate the growth and biochemical responses to salt stress. Pokkali, IR 29, and non-transgenic Nipponbare were used as tolerant, susceptible, and isogenic control, respectively. Plants were grown in plastic trays filled with 0  g L-1 NaCl  Yoshida nutrient solution as control and grown in 6 g L-1 NaCl as treatment. Salt injury was scored on 10, 16, and 21 days after salinization. Observation at 21 days after salinization showed that there was significant  difference  among genotypes in growth and biochemical characters. Classification  using hierarchical cluster analysis based on growth and biochemical responses showed that there were three clusters. Cluster I consisted of wild-type Nipponbare, T2.pMO.V.3.13.c.22, T2.pMO. V.1.7.a.15, T2.pMO.III.98.b.7, T2.pMO.II.231.c15, T2.pMO.III.98.b.8, T2.pMO.III.98.b.17, T2.pMO.III.98.b.3, and T2.pMO.VI.81.3.a.4. Cluster II consisted of IR 29, T2.pMO.V.3.13.c.14, T2.pMO.VI.30.1a.125, and T2.pMO.VI.30.1.a.65. However no mutant genotype was clustered with Pokkali in cluster III, which may indicate that there was no salt tolerant mutant genotype found in this research.   Keywords: salt tolerance mutant rice, growth characters, biochemical characters

Abstract

Objectives of experiments were to evaluate (1) in vitro inhibitory effects of plant extracts on Clavibacter michiganensis subsp. michiganensis (Cmm), (2) inhibitory effects of plant extracts on Cmm infected tomato seeds, and (3) effectiveness of seed treatment plus plant extracts to eliminate Cmm. After evaluating 20 plant extracts, curcuma rhizome and betel vine leaf extract, cinnamon and clove oil were selected for further test. Tomato seeds were artificially inoculated with Cmm to obtain high level of infection. Part of the seeds were dipped in either suspension of selected extracts for 20 minutes and the others were matriconditioned using a mixture of burned rice hull (at 22 °C and RH 60-70%) plus either of plant extracts oils, respectively. Elimination of Cmm level from infected seeds was observed at 10 days after treatments. Results of the experiment indicated curcuma extract, betel vine extract, cinnamon oil or clove oil showed in vitro inhibitory effects on Cmm. Moreover, dipping infected seeds in either 5% of curcuma, betel vine extract, or 0.5% of clove oil or matriconditioning plus these extracts oils were effective to eliminate Cmm from infected seeds. These treatments may potentially be used and developed commercially for eliminating seedborne Cmm on infected tomato seeds.   Keywords: Bacterial cancer, seedborne-pathogen, seed-treatments

Abstract

Genotype by environment (GE) interaction and stability of a trait in any crop plant such as soybean (Glycine max L. Merr.) are very important for plant breeders to develop and evaluate the new cultivars as well as for farmers to plant suitable cultivars for commercial purpose. Crop performances including harvesting date, yield components and grain yield of nine genotypes of soybean were evaluated at three locations with distinct environments in Riau. The data were used to determine GE interaction variance components of the traits and yield stability.  There was significant effect of location on all characters except on grain yield per plot.  The genotypes differed significantly in all yield components and grain yield.  Genotype x environment interaction significantly affected several crop performances such as harvesting date, all yield components and grain yield.  The magnitude of GE interaction variance component was greater than that of location for all traits except the number of seed per plant indicating that most genotypes performed differently across the locations and were not stable with respect to the locations.  Among the nine genotypes, line 19BE and Malabar are classified as stable genotypes and could be grown in wide area of Riau Province, while line 13ED and Kipas Putih produced high grain yield in specific area and could be only grown in Pekanbaru.   Keywords: genotype x environment interaction, yield components, stability, soybean

Abstract

water deficiency. Genetic engineering at the level of transcription factors (TF) is particulary a promising strategy in developing drought tolerant rice cultivar. HD-Zip genes are TF that function in plant adaptation to some environmental stresses including water deficit. The recombinant plasmid pC1301H Oshox6 which contained HD-Zip Oshox6 gene was placed under a drought inducible promoter called LEA promoter, gusA and hpt genes were driven with CaMV promoter. The aim of research was to obtain indica rice transgenic plants of Batutegi and Kasalath cultivars using pC1301H Oshox6 plasmid. Recombinant plasmid was transformed into immature rice embryos using Agrobacterium tumefaciens. Kasalath cultivar showed a better capacity to form embryogenic calli compared to Batutegi. Transformation efficiency of Batutegi is lower (1.5 - 0.3%) than Kasalath (2.2-28.3%). Regeneration efficiency is 25-83.3% and 7.7-100% for Batutegi and Kasalath, respectively. Number of putative transformant plantlets of Batutegi and Kasalath are 63 and 48 plantlets, respectively. Southern blot analysis (using hpt probe) on 12 independent lines of each Batutegi and Kasalath cultivars showed different gene copy number, ranging from one to four copies of gene.   Keywords: agrobacterium tumefaciens, LEA promoter, HD-Zip Oshox6, rice

Abstract

The objective of this research was to evaluate the response of somaclonal peanut plants regenerated from repeated cycles of in vitro selection on medium containing 15% polyethylene glycol (PEG; w /v, corresponding to - 0.41 Mpa osmotic potential) against drought stress. The R2 generation of peanut plants were used in this experiment with cv "Kelinci" and "Singa" as control cultivars. Drought treatment was the plants irrigated with water to fi eld capacity (optimum condition) while other plants were grown under water deficit. Drought treatment was given at 16 to 85 days old peanut plants; after 85 days old, the plants were treated under optimum condition until plants were ready to harvest. Drought stress was measured using drought sensitivity index value (S) on scored parameters. Results of the experiment showed that peanut lines produced from repeated cycles of in vitro selection in medium containing 15% PEG were more tolerant to water deficit, had a better vegetative growth, a higher dry pod yield, and a lower dry pod yield reduction. This research demonstrated that repeated cycles of in vitro selection method was effective to produce drought tolerant peanut genotypes with a higher proline content than genotypes without in vitro selection.   Keywords : somaclonal variation, polyethylene glycol, drought tolerance

Abstract

The objective of the experiment was to investigate the physical and chemical characteristics of three stadia of maturity based on a range of peel color from green to yellow or based on percentage of the yellow area of fruit peel (stadium 1 = 25-49 % yellow, stadium 2 = 50-74 % yellow, and stadium 3 = above 75 % yellow) on six genotypes of papaya. Each genotype exhibited different days to maturity for each stadium. The fruits of stadium 1, 2 and 3 for IPB 1 were picked at 130, 135, and 140 days after anthesis (DAA); IPB 10A at 160, 165, and 170 DAA;  IPB 1 x PB 174 at 135, 140 and 145 DAA; while PB 174,  IPB 1 x IPB 10A and IPB 10A x PB 174 were picked at 140, 145 and 150 DAA, respectively. The results indicated that peel firmness was affected by maturity stage on female fruit of IPB 10A. Maturity stage affected chemical characteristics of papaya included total soluble solids (TSS) content (IPB 10A, female fruit of  PB 174, female fruit of IPB 1 x IPB 10A, and female fruit of IPB 1 x PB 174), vitamin C content (hermaphrodite fruit of 10 A, female fruit of IPB 1 x IPB 10A) and juice pH (hermaphrodite fruit of  IPB 1).  IPB 1 genotype can be harvested at all stadia of maturity stage. Hermaphrodite and female fruit of IPB 10 A, female fruit of  PB 174, female fruit of  IPB 1 x IPB 10A and female fruit of IPB 1 x  PB 174 genotype would be better harvested at stadium 3 of maturity stage.   Keywords: Carica papaya, papaya genotype, hermaphrodite fruit, female fruit, fruit quality, fruit maturity stage
