Abstract

This study was conducted to evaluate root exudates from sub-Saharan indigenous weed species to induce germination of Strigahermonthica(Del.) Beth., a root parasitic weed.Significant variation in Striga seed germination was observed, ranging from an absence to the induction of 74.1% Striga seeds. Direct comparison of Striga germination was obscured by differences in weed root biomass as within most of the species, a direct proportional relation between Striga seed germination and weed root dry weight was observed. Expression of Striga seed germination in % g-1root dry weight (GIC) was found a suitable solution, as stable values for GIC were obtained, despite considerable variation in root dry weight. GIC was significant for 25 species and highest with Commelinaforskalaeiand Sesamumalatum(9.91; 9.78 % g-1 dry root, respectively). Striga seeds did not germinate following application of exudates from Mitracarpusscaberand Phyllanthuspentrandus. These results show that a substantial number of indigenous weed species may serve as alternative trap crops to control the parasites seed bank. Furthermore, the timing of weeds in the cropping system may provide a (partial) explanation for the erratic infestation levels found across fields and years that has dazedresearchers for many years. Keywords: Strigahermonthica, seed germination, indigenous weeds, root exudates, seed bank

Abstract

A field experiment was conducted at the Research Station of Brawijaya University from April to August 2009.  An augmented, randomized complete block design with seven blocks was utilized with seven parental clones as standard treatments and seven half-sib families as augmented treatments. Each block consisted of seven parental clones plus one randomly assigned family of half-sibs. In addition, the first block contained 29 accessions, the 2nd block had 120, the 3rd block had 194, the 4th block had 45, the 5th block had 28, the 6th block had 186, and the 7th block had 108. Ten cuttings of each parental clone was planted in each block, along with a single plant of each accession at a spacing of 75 cm in the row and 100 cm between the rows. There were five improved clones identified with high protein content and high yield. Broad-sense heritability and genetic advance of storage root weight, storage root number, percentage dry matter and protein content were high, whereas vegetative biomass and harvest index were low. The results showed that storage root weight, storage root number, percentage dry matter and protein content could be used as the basis for a crop improvement program in sweet potato.   Keywords: broad sense heritability, expected genetic advance, improved clones, high yied, protein content, sweet potato

Abstract

In 2011, we found a new bacterial disease characterized by wilt, dwarf and blight symptoms on sweet corn in Batu, East Java, Indonesia. The objective of this study is to characterize the causal agent of the disease. In this study, several assays were conducted, including hypersensitive response, pathogenicity, physiological and biochemical characteristics, PCR detection  using two specific species primer pairs for Pantoea stewartii pv. stewartii, and homology analysis of 16S rRNA gene sequence. Four Gram-negative, non-motile, facultative anaerobic bacteria were isolated from the diseased tissue. Only two strains, BD1 and BB2, gave positive result in hypersensitive reaction, pathogenicity, and Koch’s postulate assays. BB2 and BD1 strains also showed positive results in the PCR amplification using specific primers derived from the P. stewartii subsp. stewartii 16-23S gene region of but showed negative result when using primers derived from P. stewartii subsp. stewartii hrpS gene region. Sequence of partial 16S rRNA gene of BD1 and BB2 showed highest homology at 96%  to P. stewartii subsp. stewartii strain ATCC 8199 (NR. 044800.1). This results suggest that bacterial pathogens isolated from sweet corn in Batu were strains of  Pantoea spp. Keywords : Zea mays, Pantoea spp, wilt, leaf blight, PCR

Abstract

Superior hybrid and CMV tolerant cultivar development requires a pair of high heterobeltiosis parents and both of which are CMV tolerant.  Gene introgression has to be accomplished if the tolerance does not exist in the parents. This research was objected to employ DNA markers and morphological traits on identifying the most resemble BC3 CMV tolerant individuals to their recurrent parents to shortcut the backcrossing cycle. This research used fifteen BC3 populations generated from crosses of hybrid parents PBC1354 and PBC378 with tolerant parents of C1024, C1042 and C1043.  The BC3 populations were previously selected for their CMV tolerance and were characterized by RAPD technique and morphological traits. Selection by means of both RAPD marker and morphological traits identified BC3 individuals 99.9% resemble to their recurrent parent. Genotypes B3A24-20, B3A29-13, B3A29-22, B3B12-13, B3B37-9, B3B12-25, B3C16-5, B3C16-16, B3C34-18 99.9% were similar to PBC378, and  B3D11-8, B3D11-17, B3D38-5, B3E12-17, B3E20-22, B3E31-19  were 99.9% similar to PBC1354.   Those genotypes were both similar to their recurrent parent and tolerance to CMV. The employed strategy shortcut CMV tolerance genes introgression through a backcross breeding.

Abstract

This paper investigates the use of multi spectral satellite data for cropping pattern monitoring in paddy field. The southern coastal of Citarum watershed, West Java Province was selected as study sites. The analysis used in this study is identifying crop pattern based on growth stages of wetland paddy and other crops by investigating the characteristic of Normalized Difference Vegetation Indices (NDVI) and Wetness of Tasseled Cap Transformation (TCT) derived from 14 scenes of Landsat TM date 1988 to 2001. In general, the phenological of growth stages of wetland paddy can be used to distinguish with other seasonal crops. The research results indicate that multi spectral satellite data has a great potential for identification and monitoring cropping pattern in paddy field. Specific character of NDVI and Wetness also can produce a map of cropping pattern in paddy field that is useful to monitor agricultural land condition. The cropping pattern can also be used to estimate irrigation water needed of paddy field in the area. Expected implication of the information obtained from this analysis is useful for guidance more appropriate planning and better management of agricultural.

Abstract

Virulence of fungus Beauveria bassiana as pathogen on insect can be predicted according to phenotypic character in colony morphology. First of all, isolates of three different habitats were taken. Furthermore, their phenotypic characters was further characterised in B. bassiana colony and the colony growth rate was also monitored. The three natural habitats comprised insects, soil in tomato plantation and the surface of tomato leaves. The result showed that B bassiana isolate managed to be isolated from the three natural habitats involving larva Spodoptera litura and Helicoverpa armigera, the soil, and surface of tomato leaves. B bassiana isolate of insect habitat represented phenotype in colony morphology with curved character, while isolate of the leaves’ surface and soil indicated phenotype in colony morphology with raised and bowl-shaped character. In addition to the colony characters, varied growth rate was also indicated by isolate from each habitat. Isolate of insect with curved colony character represented higher growth rate than that of the leaves’ surface or the soil with raised and bowl-shaped colony character. The colony with curved character represented phenotypic character of isolate B bassiana with high growth rate. Thus, B. bassiana isolate with the curved colony of insect served as an isolate which was expected to be virulent as controlling agent to biological elements.       Keywords: B. bassiana isolate, phenotypic characters in colony morphology, colony growth rate, habitat of fungus

Abstract

Beetle activity deep inside wood was studied in field (Mt. Yoshida, Kyoto) and laboratory conditions by monitoring the type and amount of frass ejected from beetle galleries of Platypus quercivorus. Twenty-one galleries were selected from five infested Quercus serrata trees for field studies. In the laboratory, frass production was monitored for three galleries using a computer-aided electrical balance (A&D Co. Ltd.). Long-term patterns of frass production from field observation revealed that there are three distinguishable stages; a fibrous frass stage, an intermediate stage, and a powdery frass stage. The duration of the fibrous frass production was clearly different between galleries, ranging from five to twenty one days. The intermediate stage was also different from gallery to gallery, ranging from two to twenty days. Accordingly, the starting time of the third stage, powdery frass production, ranged from the 19th to the 27th day. Under laboratory conditions, the long-term patterns of frass production revealed that in galleries of logs no. 1 and 2 the fibrous frass period was stopped on the 23rd and 22nd day, respectively. Field monitoring revealed there was a negative relationship between the length of fibrous frass stage and the length of the intermediate stage.   Keywords:  fibrous frass stage,  intermediate stage, Platypus quercivorus, powdery frass stage

Abstract

This research focuses on investigating West Kalimantan’s traditional landscapes, shifting cultivation pattern, and comparing the forest dependency of several ethnic groups.  After conducting remote sensing and geographical information system techniques based on the satellite images LANDSAT-TM in West Kalimantan from 1996 to 2006, the decrease of primary dry tropical forest from 36.4% to 15.9% and a little increase of agriculture land from 44.8% to 45.1% were detected. West Kalimantan’s traditional landscape is a combination of primary forest, shifting dry rice-field, rubber plantation, fruits garden and home garden, meanwhile new landscape managed by migrants mainly consist of permanent wet land rice-field, dry land rice, and crop fields. The decreasing forest area forces the native people to shorten the shifting cultivation cycle or to turn to permanent agriculture with the low yield. This situation is the result in the more primary forest clearing for agriculture usage by native people and migrants. It is clear that the traditional landscape of West Kalimantan is particularly dependent upon its most vital element, the forest. Yet, traditional landscape representing the regeneration cycle of forest in West Kalimantan was constrained by changes in managed and modern landscape.

Abstract

The inheritance pattern of resistant tomato to root-knot nematode was studied. GM2 accession and Gondol Putih (GP) cultivars were used as resistant and susceptible parent, respectively. Parental plants, F1 generation, and the F2 generation were grown individually in the sterile soil. One thousand of larvae stage 2 (L2) nematode of M. incognita was infested in each plant. Data of root gall intensity, the number of egg mass, population of L2 nematodes in root and soil were analyzed with the Kormogorov-Smirnov’s test, Chi-square test, and potence ratio. The F2 selected resistant plants then were grown and self fertilized to identify of homozygote plants (F2) related to nematode resistant and good fruit characters. The result showed that the resistant to root-knot nematode was controlled by a dominant gene. Positive correlation between damage levels of roots, eggs mass number and L2 larvae population in the root was significant. Eleven selected plants, conferred the homozygous resistant gene, was prospective lines to be used pedigree or single seed descent selection in producing variety with resistant to nematode, high yield and quality of fruit.   Keywords: tomato, root-knot nematode, resistant gene, dominant, homozygous, correlation
