Abstract:

Many development projects in Vietnam today, including tourism, are partially focused on ecology. However, the mentality of cultivating for later gains is still popular. In addition to the goal of creating opportunities to benefit local communities, this development discourse conveys a sense of ‘ecoambiguity’. This study mainly applies the concept of "ecoambiguity" of Thornber (2012) to discuss the current situation and impact of tourism activities in the Khmer community around Bà Om Pond in Trà Vinh, Vietnam. Unlike previous works that discussed the beauty and value of Khmer religion, temples, rural life, festivals, and art, this research argues that people-centered policies have never enabled people to achieve their goals.

Abstract:

With help of the nonequilibrium Green’s function technique and the Feynman path integral theory, we present a self-consistent approach to the Thornber-Feynman model of a polaron under high electric field. The applied field and the electron-phonon interaction both are treated non-perturbatively so that the high-field effect as well as the quantum interference effect have been taken into account. A set of coupled equations are derived to consistently describe the drift motion and the fluctuation of the electron. By solving these equations numerically we obtain (1) the nonlinear relation between the drift velocity and the applied electric field; (2) the effective electron temperature, the nonequilibrium noise, and the distribution functions.

Abstract:

AbstractA theoretical model for electrons in the conduction band intend to investigate the optical breakdown threshold in femtosecond laser pulse-fused silica interaction is presented. The model is derived from a rate equation that includes the avalanche and multi-photon ionization processes of Thornber and Keldysh, respectively, and also the three-body and exciton recombination mechanisms. In addition, the time evolution of electron mean energy is also considered through the energy balance equation. The mean energy acts as a trigger for the avalanche mechanism. The evolution of electron density profiles is calculated and discussed with respect to the ionization and recombination mechanisms. The results for the fluence threshold as a function of the pulse duration fall in good agreement with the experimental data reported in the literature.

Abstract:

In this paper, we present a mesoscopic-macroscopic model of self-consistent charge transport. It is based upon an asymptotic expansion of solutions of the Boltzmann Transport Equation (BTE). We identify three dimensionless parameters from the BTE. These parameters are, respectively, the quotient of reference scales for drift and thermal velocities, the scaled mean free path, and the scaled Debye length. Such parameters induce domain dependent macroscopic approximations. Particular focus is placed upon the so-called high field model, defined by the regime where drift velocity dominates thermal velocity. This model incorporates kinetic transition layers, linking mesoscopic to macroscopic states. Reference scalings are defined by the background doping levels and distinct, experimentally measured mobility expressions, as well as locally determined ranges for the electric fields. The mobilities reflect a coarse substitute for reference scales of scattering mechanisms. See [9] for elaboration.The high field approximation is a formally derived modification of the augmented drift-diffusion model originally introduced by Thornber some fifteen years ago [25]. We are able to compare our approach with the earlier kinetic approach of Baranger and Wilkins [5] and the macroscopic approach of Kan, Ravaioli and Kerkhoven [20].

Abstract:

Uno de los principales problemas que enfrentan los productores forestales es la incógnita de saber cómo estimar el volumen de madera que tienen en su área boscosa, a partir de datos obtenidos de un inventario forestal. Las ecuaciones de volumen y sus expresiones tabuladas son una de las principales herramientas para conocer, de manera confiable, las existencias reales y realizar un manejo sostenible, así como para la gestión forestal. En este contexto, se realizó un estudio para elaborar ecuaciones y tablas de volúmenes para Pinus lawsonii y P. oocarpa en la zona sur de la Sierra Purhépecha. La toma de datos de campo se llevó a cabo mediante el derribo y cubicación de 152 árboles de P. lawsonii y 83 para P. oocarpa. Se ajustaron y compararon los modelos de Schumacher-Hall , Thornber , Spurr con variable combinada aritmética, Spurr con variable combinada logarítmica y Korsun, los cuales presentaron valores de R2 ajustada entre 0.97 a 0.99 estadísticos de Durbin Watson cercanos a 2; la prueba de Shapiro-Wilk muestra una buena distribución de los residuales. Un análisis ponderado concluyó que para la estimación del volumen de árboles en pie, el modelo de Schumacher-Hall fue el de mejor ajuste. La prueba de homogeneidad de varianzas indica que se puede emplear de manera indistinta este modelo para ambas especies.

Abstract:

Purpose of the study: This research explores Somaly Mam's The Road of Lost Innocence through the perspective of gender subaltern in which she calls for collective activism to empower sexual slave girls' position and status in society. She raises her voice against the dominant social force to establish her own space and other sexed women's space in society Methodology: This research is qualitative in nature. To analyze the selected text, few critics and writers have observed the text from different perspectives. Theories of Spivak, Guha, Suzette R Grillot, Heidi Hoefinger, Nicholas Kristof, Abigali Pesta, and Karen Thornber support this research to find the answers to the research questions. Main Findings: Mam depicts unspeakable acts of brutality with sexual slave girls in brothels. Through writing, she appeals to all people in the world to take the issue of sexuality and girl trafficking seriously which is horrible these days. Applications of this study: This paper will emphasize Mam's subaltern consciousness which is ambivalent consciousness. Mam requests for collective activism to eradicate women's exploitation from the world. Her activism looks contributory but paradoxical. Novelty/Originality of this study: The study is novel in its approach and methods of research in autobiographical literature. Despite being an orphan, domestic and sexual slave girl, Mam succeeds to be an activist and reformist through her struggle. Her activism plays important role in the field of sexual slavery and girl trafficking.

Abstract:

Filenchus cylindricus (Thorne & Malek, 1968) Niblack & Bernard, 1985 was reported from the sandy rhizospheric soils of Poa pratensis and for the first time in Korea. Females and males are molecularly characterized and morphological and morphometric data supplied. Identification was made using an integrative approach considering morphological characteristics and inferences drawn from the analyses of the D2-D3 expansion segment of 28S rRNA and ITS1-5.8S-ITS2 of rRNA partial sequences. Females and males from Korea conform to the type descriptions and also to subsequent species descriptions from Iowa and Colorado USA, Sudan and Pakistan. Despite the close morphological and morphometric similarities with F. thornei (Andrássy, 1954) Andrássy, 1963, the two species can be adequately differentiated based on molecular data inference.

Full text

Abstract:

The root-lesion nematode, Pratylenchus thornei, can reduce wheat yields by >50%. Although this nematode has a broad host range, crop rotation can be an effective tool for its management if the host status of crops and cultivars is known. The summer crops grown in the northern grain region of Australia are poorly characterised for their resistance to P. thornei and their role in crop sequencing to improve wheat yields. In a 4-year field experiment, we prepared plots with high or low populations of P. thornei by growing susceptible wheat or partially resistant canaryseed (Phalaris canariensis); after an 11-month, weed-free fallow, several cultivars of eight summer crops were grown. Following another 15-month, weed-free fallow, P. thornei-intolerant wheat cv. Strzelecki was grown. Populations of P. thornei were determined to 150 cm soil depth throughout the experiment. When two partially resistant crops were grown in succession, e.g. canaryseed followed by panicum (Setaria italica), P. thornei populations were <739/kg soil and subsequent wheat yields were 3245 kg/ha. In contrast, after two susceptible crops, e.g. wheat followed by soybean, P. thornei populations were 10 850/kg soil and subsequent wheat yields were just 1383 kg/ha. Regression analysis showed a linear, negative response of wheat biomass and grain yield with increasing P. thornei populations and a predicted loss of 77% for biomass and 62% for grain yield. The best predictor of wheat yield loss was P. thornei populations at 0–90 cm soil depth. Crop rotation can be used to reduce P. thornei populations and increase wheat yield, with greatest gains being made following two partially resistant crops grown sequentially.

Abstract:

In the subtropical grain region of eastern Australia, two experiments were conducted, one initially with 2490 P. thornei/kg soil, the other with 8150 P. thornei/kg soil at 0–0.9 m soil depth. We determined the effect of P. thornei, residual from a weed-free fallow and pre-cropping with several cultivars each of barley (Hordeum vulgare), faba bean (Vicia faba), chickpea (Cicer arietinum), and wheat (Triticum aestivum) (Phase 1), on the growth of wheat cultivars with intolerance or tolerance to P. thornei (Phase 2). Pratylenchus thornei substantially increased after growing all cultivars of the Phase 1 faba bean, barley, and most cultivars of chickpea and wheat, and decreased after two moderately resistant wheat cultivars and the fallow treatment. The biomass of the Phase 2 tolerant cultivar ranged from 5070 to 6780 kg/ha and the intolerant cultivar 1020 to 4740 kg/ha. There was a negative linear relationship between P. thornei population densities and biomass of the Phase 2 intolerant cultivar but not of the tolerant cultivar. Growers are at risk of financial loss because they are restricted in their choice of crops to reduce damaging population densities of P. thornei. The development of resistant and tolerant crop genotypes can maximize production in P. thornei-affected farming systems.

Abstract:

Summary The root-lesion nematode, Pratylenchus thornei, attacks a wide range of crops and causes significant reductions in global grain production. Breeding programmes are currently restricted to using parents with moderate resistance to P. thornei as cereal cultivars with complete resistance are yet to be identified. This study evaluated 484 of CIMMYT’s spring wheat accessions for resistance to P. thornei of which 56 lines were pre-identified as resistant under controlled growth room conditions. These lines were further evaluated for their resistance and tolerance reactions under field conditions, where 14 accessions maintained their resistance and 16 were moderately resistant against P. thornei. Four lines gave excellent resistant and tolerance reactions to P. thornei. The relationship between the nematode reproduction factor (Pf/Pi) and wheat grain yield in field experiments fits a linear regression model. These findings could be useful for improving P. thornei resistance in wheat.

Abstract:

Plant-derived phenolic compounds contribute to the defense against various pathogens, including root-lesion nematodes (Pratylenchus spp.). However, there are no reports on the role of phenolic compounds in wheat (Triticum aestivum) against Pratylenchus thornei. In this study, wheat genotypes ranging from resistant to very susceptible to P. thornei were used to investigate the level of total phenols and phenol oxidases, polyphenol oxidase (PPO), and peroxidase (POD) expressed in root tissues when grown in the presence and absence of P. thornei over time (2–8 weeks). Higher constitutive levels of total phenols were found in resistant synthetic hexaploid wheats CPI133872 (576 µg gallic acid equivalent (GAE)/g root) and CPI133859 (518 µg GAE/g root) at 8 weeks after sowing, compared with moderately resistant and susceptible genotypes (192 to 390 µg GAE/g root). The activity of PPO was induced in resistant (CPI133872) and moderately resistant (GS50a and its derivate QT8343) genotypes, becoming maximal at 4 weeks after P. thornei inoculation. The activity of POD was induced in CPI133872 at 6 weeks after P. thornei inoculation. Different genetic sources of resistance to P. thornei showed diverse defense mechanisms and differences in timing responses. The combined effects of total phenols and oxidative enzymes could be important for defense against P. thornei in some resistant wheat genotypes.

Abstract:

Factors responsible for a decline in wheat yields in some paddocks in the Gunnedah (northern New South Wales) area were investigated in a series of field experiments. Yield decline is not apparent on soils cultivated for less than 10 years, and barley and sorghum crops are not affected. Plant nutrition apparently is not a major factor in the decline, because, although there was a small response to zinc application in 1 experiment, wheat yields were not significantly increased by the application of N, P, K, Cu, Mg, B, Mn, Mo or S in a paddock where the yield of wheat was half that of the surrounding barley crop. Fumigation of the soil with methyl bromide increased wheat cv. Timgalen yield by 78% to equal that of barley cv. Clipper in a second experiment. Large numbers of root lesion nematodes (Pratylenchus thornei) were associated with unfumigated wheat plots, with smaller numbers present on barley plots. In a third experiment, the grain yields of all of the 9 cereal genotypes tested were increased when sown with 4 kg/ha of aldicarb. The relative yield increase associated with aldicarb showed good correlation with the reputed tolerance of the genotypes to P. thornei. Pratylenchus thornei occurred to a depth of 120 cm. Aldicarb did not affect P. thornei numbers below 15 cm, while methyl bromide controlled P. thornei to depths of 30-90 cm. Aldicarb virtually eliminated P. thornei from the surface 10 cm of soil, but had no effect on the incidence of the fungal diseases common root rot (Bipolaris sorokiniana) or crown rot (Fusarium graminearum). Soil fumigation with methyl bromide controlled B. sorokiniana and F. graminearum as well as P. thornei and gave yields 9% higher than did treatment with aldicarb. In another experiment, ethylene dibromide (2.7-10.8 L/ha) had no consistent effect on the yield of wheat or numbers of P. thornei while terbufos (0.6 and 1.2 kg/ha) gave a small reduction in P. thornei numbers and a small increase in yield. These data indicate that P. thornei is at least partially responsible for wheat yield decline in parts of northern New South Wales.

Abstract:

Resistance to the root-lesion nematode Pratylenchus thornei was sought in wheat from the West Asia and North Africa (WANA) region in the Watkins Collection (148 bread and 139 durum wheat accessions) and the McIntosh Collection (59 bread and 43 durum wheat accessions). It was considered that landraces from this region, encompassing the centres of origin of wheat and where P. thornei also occurs, could be valuable sources of resistance for use in wheat breeding. Resistance was determined by number of P. thornei/kg soil after the growth of the plants in replicated glasshouse experiments. On average, durum accessions produced significantly lower numbers of P. thornei than bread wheat accessions in both the Watkins and McIntosh Collections. Selected accessions with low P. thornei numbers were re-tested and 13 bread wheat and 10 durum accessions were identified with nematode numbers not significantly different from GS50a, a partially resistant bread wheat line used as a reference standard. These resistant accessions, which originated in Iran, Iraq, Syria, Egypt, Sudan, Morocco, and Tunisia, represent a resource of resistance genes in the primary wheat gene pool, which could be used in Australian wheat breeding programs to reduce the economic loss from P. thornei.

Abstract The introgression wheat line H93-8 (bearer of the gene Cre2 for resistance to Heterodera avenae) was evaluated for response to Pratylenchus thornei and H. avenae in a 5-month field experiment in comparison with its progenitors and other wheat cultivars. Previously, the response of H93-8 to P. thornei was compared to other T. aestivum cultivars under controlled conditions in a 2 month laboratory assay. Line H93-8 was resistant to P. thornei under controlled conditions: after two months the nematode populations were less than half that in cv. Anza and H93-8 plants while they clearly increased in cvs Loros and Rinconada. Under field conditions, fewer H. avenae females were found in H93-8 and its wild donor Aegilops ventricosa than in the H10-15 wheat parent and the bridge species T. turgidum. No significant differences in the number of H. avenae indicated similarity between the resistance conferred by Cre2 in line H93-8 and that regulated by Cre1 in cv. Loros. The parental line H10-15 hosted nearly half as many females as the susceptible control Capa, but as many as Rinconada. The variability observed in host responses to P. thornei when analysed under controlled conditions or in the field, makes it advisable to carry out both kinds of studies for the assessment of resistant cultivars. Results in the field trial suggest that approximately 5 months is the most secure time period to detect real differences in response to P. thornei due to penetration rates and reproduction of these nematodes depending on the line or variety. During the first 2.5 months, the population of P. thornei increased quickly in H93-8 but, at ear emergence, this line hosted similar numbers to its parents, Ae. ventricosa and H10-15. T. turgidum was clearly the most susceptible host in the field to P. thornei. The controls Rinconada and Loros were the least susceptible among the plants tested in the field but, at the end of the experiment, they were significantly different only from T. turgidum. So, it was possible to detect a differential host response or different levels of susceptibility, but none of the tested cultivars or wheat lines was clearly resistant to P. thornei under field conditions. Finally, a negative correlation between H. avenae and P. thornei populations was detected in the field after 5 months only on cv. Loros.

Vorher war die Reaktion von H93-8 auf P. thornei in einem zweimonatigen Laborversuch unter kontrollierten Bedingungen mit anderen Sorten von Triticum aestivum verglichen worden. Die Linie H93-8 war unter kontrollierten Bedingungen resistent gegen P. thornei: nach zwei Monaten waren die Nematodenpopulationen an H93-8 und der Sorte Anza um mehr als die Halfte geringer als die inokulierte Nematodenanzahl, wahrend sie an den Sorten Loros und Rinconada deutlich zugenommen hatten. Unter Feldbedingungen wurden an H93-8 und dem wilden Spender Aegilops ventricosa weniger Weibchen von H. avenae gefunden als an dem H10-15 Weizenelter und der Bruckenart T. turgidum. Das Fehlen deutlicher Unterschiede in der Anzahl der Weibchen von H. avenae wies auf eine Ahnlichkeit zwischen der durch Cre2 in die Linie H93-8 ubertragenen und der durch Cre1 regulierten Resistenz in der Sorte Loros hin. Die elterliche Linie H10-15 beherbergte nur etwa halb soviele Weibchen wie die anfallige Capa, doch genau soviele wie Rinconada. Die unter kontrollierten Bedingungen sowie im Feldversuch beobachtete Variabilitat der Wirtsreaktionen gegenuber P. thornei lasst es ratsam erscheinen, bei der Bewertung der Resistenz beide Arten von Versuchen durchzufuhren. Die Ergebnisse des Feldversuches zeigen, dass etwa funf Monate der sichersten Zeitraum ist, um wirkliche Unterschiede in der Wirtsreaktion auf P. thornei zu finden, da die Einwanderungs- und Vermehrungstraten je nach Linie und Sorte unterschiedlich sein konnen. Wahrend der ersten 2,5 Monate stieg die Population von P. thornei in H93-8 schnell an, aber beim Ahrenschieben beherbergte diese Linie ahnliche Anzahlen wie ihre Eltern Ae. ventricosa und H10-15. T. turgidum war im Feld deutlich der anfalligste Wirt fur P. thornei. Die Kontrollen Rinconada und Loros waren die am wenigsten anfalligen der im Feldversuch gepruften Pflanzen, doch bestanden bei Versuchsende nur zu T. turgidum signifikante Unterschiede. Es war also moglich, eine Differentialwirtreaktion oder unterschiedliche Grade der Anfalligkeit zu entdecken, jedoch war keine der gepruften Sorten oder Weizenlinen unter Feldbedingungen deutlich resistent gegen P. thornei . Eine negative Korrelation zwischen den Populationen von H. avenae und P. thornei wurde im Feld nach funf Monaten nur an der Sorte Loros gefunden.

Abstract:

The root lesion nematode Pratylenchus thornei causes economic losses in wheat and barley internationally through both reduced grain yield and grain quality. This study investigated the relationships between the presowing P. thornei density and grain yield and the postharvest nematode densities. Four field experiments were conducted at the same site between 2010 and 2014. A range of presowing P. thornei densities was established in the first year by growing three cereal cultivars that ranged from resistant to susceptible. In the following year, plots were sown with the five same cereal cultivars. A linear relationship was observed between the natural log of the presowing P. thornei density and grain yield across all seasons. The results showed that grain yield losses varied between cultivars and seasons. The importance of season was significant, with this study conducted over several seasons, and it highlighted the variability in yield losses between seasons, which will need further investigation. The greatest yield losses observed were 25 to 28% when the maximum presowing P. thornei densities ranged between 150 and 250 P. thornei g of soil−1. An analysis of the relationship between the presowing and postharvest nematode densities revealed that increased presowing nematode densities resulted in decreased multiplication rates in all seasons and in all cultivars. Nematode multiplication rates also varied between seasons. These results explain why it is difficult to predict nematode levels based on cropping history, and additionally, they highlight the importance of growing resistant cultivars to maintain low levels of P. thornei to minimize risk of yield losses.

Abstract:

In two experiments on a farm practicing conservation agriculture, the grain yield of a range of wheat cultivars was significantly (p < 0.001) negatively related to the post-harvest population densities of Pratylenchus thornei in the soil profile to 45 cm depth. In a third and fourth experiment with different rotations, methyl bromide fumigation significantly (p < 0.05) decreased (a) a low initial population density of P. thornei in the soil profile to 90 cm depth and (b) a high initial population of P. thornei to 45 cm depth, and a medium level of the crown rot fungus, Fusarium pseudograminearum, at 0–15 cm depth to a low level. For a range of wheat and durum cultivars, grain yield and response to fumigation were highly significantly (p < 0.001) related to (a) the P. thornei tolerance index of the cultivars in the third experiment, and (b) to both the P. thornei tolerance index and the crown rot resistance index in the fourth experiment. In the latter, grain yield was significantly (p < 0.001) positively related to biomass at anthesis and negatively related to percentage whiteheads at grain fill growth stage. One barley cultivar was more tolerant to both diseases than the wheat and durum cultivars. Crop rotation, utilizing crop cultivars resistant and tolerant to both P. thornei and F. pseudograminearum, is key to success for conservation farming in this region.

PROPRIETARY ESTOPPEL: A NEW CHAPTER DAWNS?The decision of the Court of Appeal in Thorner v Major1 briefly constructed an almost impossible strait-jacket around potential claimants under proprietary estoppel, reminiscent of the way the strict requirements under the Willmot v Barber2 probanda had earlier limited such claims3. The Court of Appeal held in Thorner v Major4 that an assurance of rights had to be clear and unequivocal in order to give rise to property rights and on the facts of this case the assurances had been too vague to give rise to such rights. In an area of law based on informality and often vague promises it appeared that the law was now in retrenchment and was reasserting the need for very strict limitations on the circumstances in which property claims under proprietary estoppel could arise.

Abstract:

Pratylenchus thornei, a nematode species that feeds and reproduces in chickpea (Cicer arietinum) roots, is widespread throughout the Mediterranean basin and Indian subcontinent. In Australia, it can cause yield losses up to approximately 25% of intolerant chickpea cultivars. Potential for improvement has been hindered by the narrow genetic diversity of cultivated chickpea and a limited world collection of original wild Cicer spp. in the primary gene pool, consisting of 18 C. reticulatum and 10 C. echinospermum accessions. Recently, collections of C. reticulatum and C. echinospermum from Turkey have substantially increased the number of accessions. This study evaluated 133 C. reticulatum and 41 C. echinospermum accessions from the new collection for resistance to P. thornei under controlled conditions in repeated glasshouse pot experiments. The aim of the study was to identify accessions with resistance superior to that currently available in Australian germplasm. Both wild Cicer spp. were found, on average, to be more resistant to P. thornei (P < 0.001) than C. arietinum. Combined analyses across experiments to determine genetic rankings showed that 13 (7%) wild accessions were significantly more resistant than the most resistant C. echinospermum reference ILWC 246, while another 40 (23%) accessions were significantly more resistant than the least susceptible Australian chickpea cultivar PBA Seamer. Mean P. thornei population densities differed significantly between collection sites in Turkey and within each of the genetic population groups. The sites Kayatepe and Baristepe1, and genetic population groups Ret_A and Ret_F associated with sites Oyali and Baristepe1, produced the lowest P. thornei population densities. This is the first report assessing the resistance to P. thornei of this new collection which offers novel sources of P. thornei resistance and untapped genetic diversity valuable for international chickpea breeding programs to exploit.

Abstract:

Root-lesion nematode (Pratylenchus thornei Sher and Allen) causes substantial loss in yield of wheat in eastern Australia. Central Asian accessions of Aegilops tauschii Coss. were tested to find new sources of resistance to P. thornei for use in wheat-breeding programs. Ae. tauschii (2n = 14, DD genome) is one of the wild progenitors of wheat, Triticum aestivum L. (2n = 42, AABBDD genomes). Resistance was determined by nematode reproduction in the plant roots during 16 weeks of growth in pots in a glasshouse. Thirty-nine of 244 accessions of Ae. tauschii tested in 2 replicated experiments had lower numbers of nematodes than GS50a, a partially resistant line of wheat used as a resistance standard. Resistance to P. thornei was present in accessions of most taxonomic groups within Ae. tauschii, i.e. Ae. tauschii subsp. strangulata (Eig) Tzvel., and Ae. tauschii subsp. tauschii var. typica L. and var. meyeri (Griseb.) Tzvel. Resistance was most common in subsp. strangulata with 20 out of 40 strangulata accessions in the resistant group and none in a highly susceptible group of 43 accessions. Accessions of var. meyeri with the Cre3 gene for effective resistance to cereal cyst nematode (Heterodera avenae Woll.) were also resistant to P. thornei. The results indicate that several resistances to P. thornei are present in Ae. tauschii subspecies and varieties, which could be introgressed into cultivated wheat to help control P. thornei and increase farm profits.

Abstract:

Root-lesion nematode (Pratylenchus thornei) significantly reduces wheat yields in the northern Australian grain region. Canola is thought to have a ‘biofumigation’ potential to control nematodes; therefore, a field experiment was designed to compare canola with other winter crops or clean-fallow for reducing P. thornei population densities and improving growth of P. thornei-intolerant wheat (cv. Batavia) in the following year. Immediately after harvest of the first-year crops, populations of P. thornei were lowest following various canola cultivars or clean-fallow (1957–5200 P. thornei/kg dry soil) and were highest following susceptible wheat cultivars (31 033–41 294/kg dry soil). Unexpectedly, at planting of the second-year wheat crop, nematode populations were at more uniform lower levels (<5000/kg dry soil), irrespective of the previous season’s treatment, and remained that way during the growing season, which was quite dry. Growth and grain yield of the second-year wheat crop were poorest on plots previously planted with canola or left fallow due to poor colonisation with arbuscular mycorrhizal (AM) fungi, with the exception of canola cv. Karoo, which had high AM fungal colonisation and low wheat yields. There were significant regressions between growth and yield parameters of the second-year wheat and levels of AMF following the pre-crop treatments. Thus, canola appears to be a good crop for reducing P. thornei populations, but AM fungal-dependence of subsequent crops should be considered, particularly in the northern Australian grain region.

Abstract:

Summary The goal of this study was to evaluate the efficiency of Pasteuria thornei as a biological seed treatment for Pratylenchus brachyurus control in soybean (Glycine max). Seeds of soybean ‘SYN1080’ were treated with three concentrations of P. thornei endospores per seed (5 × 106, 107, 1.5 × 107), together with two other treatments for comparison: a commercial control containing abamectin (0.58 mg seed−1) and a mixed treatment containing abamectin (0.58 mg seed−1) and 107 endospores of P. thornei. These seeds were sown in plastic cups containing soil inoculated with 1000 nematodes (Trial 1) and 600 nematodes (Trial 2). The trials were evaluated at 60 and 90 days after inoculation (dai). The total of nematodes extracted from the roots of each plant was used as the assessment criterion. Only the highest concentration of P. thornei endospores (1.5 × 107) consistently reduced the final populations of P. brachyurus by 25-50% compared to the non-treated seeds. The treatments containing abamectin were superior in reducing the nematode population in all trials and evaluations. There was no visible synergistic effect of the combined use of abamectin and P. thornei in the same treatment at 90 dai.

Abstract:

Root-lesion nematode (Pratylenchus thornei) is a serious pathogen of wheat in many countries. The International Triticeae Mapping Initiative (ITMI) population of recombinant inbred lines (RILs) was assessed for resistance to P. thornei to determine the chromosome locations of the resistance genes. The ITMI population is derived from a cross between the resistant synthetic hexaploid wheat W-7984 and a susceptible bread wheat cultivar Opata 85. Two years of phenotypic data for resistance to P. thornei were obtained in replicated glasshouse trials. Quantitative trait locus (QTL) analysis was performed using available segregation and map data for 114 RILs. A QTL on chromosome 6DS showed consistent effects for reduced nematode numbers (partial resistance) across years and accounted for 11% and 23% of the phenotypic variation. A second QTL for P. thornei resistance on chromosome 2BS accounted for an additional 19% and 5%. Restriction fragment length polymorphism (RFLP) and simple sequence repeat (SSR) markers associated with the QTLs are physically located in regions rich in major genes at the distal ends of the short chromosome arms of 6D and 2B. SSR markers with potential for marker-assisted selection of P. thornei resistance effective in different genetic backgrounds have been identified.

Abstract:

The root-lesion nematode Pratylenchus thornei is a major pathogen of wheat (Triticum aestivum) in many regions globally. Resistance of wheat genotypes to P. thornei can be determined from final nematode population densities in glasshouse experiments but combining results across multiple experiments presents challenges. Here, we use a factor analytic method for multiexperiment analysis of final population densities of P. thornei for 1,096 unique wheat genotypes in 22 glasshouse experiments. The resistance to P. thornei of the genotypes was effectively represented by a two-factor model with rotation of the axes to a principal components solution. Principal axes 1 and 2 (PA1 and PA2) accounted for 79 and 11% of the genetic variance, respectively, over all experiments. Final population densities of P. thornei as empirical best linear unbiased predictors (PA[1+2]-eBLUPs) from the combined glasshouse experiments were highly predictive (P < 0.001) of final nematode population densities in the soil profile, crop canopy greenness (normalized difference vegetation index), and grain yield of wheat genotypes in P. thornei-infested fields in the Australian subtropical grain region. Nine categories of resistance ratings for wheat genotypes from resistant to very susceptible were based on subdivision of the range of PA(1+2)-eBLUPs for use in growers’ sowing guides. Nine genotypes were nominated as references for future resistance experiments. Most (62%) Australian wheat genotypes were in the most susceptible three categories (susceptible, susceptible to very susceptible, and very susceptible). However, resistant germplasm characterized in this study could be used in plant breeding to considerably improve the overall resistance of Australian wheat crops.

Abstract:

Field experiments testing rates of various nematicides, with and without NPZn fertiliser, were analysed to investigate how root-lesion nematode (Pratylenchus thornei) affects growth and yield components of susceptible/intolerant wheat cultivars in a subtropical environment. Plant response to nematode attack was assessed by regression and principal components analyses of various plant parameters at different crop development stages, in relation to different nematode population densities in the roots and root-zone soil. Reduction in P. thornei population densities by nematicides resulted in increased numbers of tillers, plant biomass, N and P concentrations and uptakes, numbers of spikes and kernels, and grain yield. Grain yield was strongly correlated with number of kernels, biomass and number of spikes, and negatively correlated with number of P. thornei in the root-zone soil at stem elongation. This study showed that P. thornei damage to roots decreased wheat yield through limiting N and P concentrations and uptakes in plant tops causing poor growth that commenced early and continued through the life of the crop. Genetic, environmental and management factors that reduce population densities of P. thornei, and decrease the impact of the nematodes starting in early crop growth, will greatly increase spike and kernel numbers and grain yield.
