New wheat genotypes tolerant to aluminum toxicity obtained by mutation induction

Seed from the sensitive wheat (Triticum aestivumL.) cultivar Anahuac was treated to gamma-ray irradiation and eleven Al3+ tolerant mutants selected. The objective was to compare these mutants to the original Anahuac and to the tolerant wheat cultivars IAC-24 and IAC-60 from 1994 to 1996 in acid (Capão Bonito) and limed (Monte Alegre do Sul) soil field trials, in the State of São Paulo, Brazil. Grain yield and agronomic characteristics were analyzed. All the mutant lines yielded higher than the sensitive Anahuac cultivar in the acid soils of Capão Bonito. Under limed soil conditions, 10 mutants had a similar yield to the original sensitive cultivar and one a lower yield. The majority of the mutants were similar in yield to the tolerant cultivars IAC-24 and IAC-60 under both conditions. Some of the mutants showed altered agronomic characteristics, but these alterations did not generally influence the grain yield. The results indicated that tolerant lines with good characteristics may be obtained from a susceptible cultivar by mutation induction, thus allowing cropping under conditions where Al3 + is a limiting factor.

A new aggregation method for strategic decision making and its application in assignment theory

A new aggregation method for decision making is presented by using induced aggregation operators and the index of maximum and minimum level. Its main advantage is that it can assess complex reordering processes in the aggregation that represent complex attitudinal characters of the decision maker such as psychological or personal factors. A wide range of properties and particular cases of this new approach are studied. A further generalization by using hybrid averages and immediate weights is also presented. The key issue in this approach against the previous model is that we can use the weighted average and the ordered weighted average in the same formulation. Thus, we are able to consider the subjective attitude and the degree of optimism of the decision maker in the decision process. The paper ends with an application in a decision making problem based on the use of the assignment theory.

Rosalía de Castro, sombra que se fai teoría

A figura auroral de Rosalía de Castro autorizou a aparición de novas poetas a finais do século XX mais, paradoxalmente, a partir da publicación dos seus libros fundacionais non xurdiu unha lexión de autoras que desde Cantares gallegos (1863) e Follas novas (1880) escribisen incesantemente a nación, ou simplemente, escribisen incesantemente en galego e tivesen por iso un recoñecemento canónico. Sen dúbida a intervención do patriarcadogaleguista provocou esa interrupción, que se entende mellor cando se teñenen conta os condicionantes socioliterarios que coutaban as mulleres escritoras (González Fernández, 2005: 15-19). Porque a finais do século XIX, e malia excepcións rechamantes, o pensamento hexemónicoconsideraba que as literatas eran unhas sabias ridículas, tal como sesancionara desde o coñecido capítulo V do Émile, ou l’Education (1762) deJean Jacques Rousseau en diante, aínda que houbese, por suposto, vocesdisidentes entre os seus contemporáneos, como Benito Jerónimo Feijoo noseu moi lido discurso XVI, Defensa de las mujeres, do seu Teatro crítico universal(1726). Nese sentido depreciativo do termo debe lerse o coñecido artigo deRosalía de Castro, Las literatas. Carta a Eduarda (1865). Por outra banda, noemerxente discurso nacionalista que vai do XIX ao primeiro terzo do XXopérase unha corrección misóxina que afecta á concepción sexuada danación.

Systematic and biogeographic relationships of the Japanese white-toothed shrew (Crocidura dsinezumi)

To assess the zoogeographic and phylogenetic relationships of C. dsinezumi, its systematic position has been investigated through electrophoretic comparisons. These comparisons comprise typical Indomalayan and Palaearctic species, including C. russula, the supposed sister taxon of the Japanese white-toothed shrew. The range of measured genetic distances that separate dsinezumi from the other shrews (Nei's D = 0.232-0.406) is typical for interspecific comparisons among Crocidura taxa. Our results reinforce morphologic considerations that suggest C. dsinezumi be treated as a valid species. Phylogenetic relationships deduced from a cladistic treatment of allozyme data refute the possibility that the western Palaearctic C. russula is the sister taxon of C. dsinezumi. Zoogeographic interpretation of the genetic results indicates that the Southeast Asian representatives constitute a clade distinct from one that includes the Palaearctic species. However, C. dsinezumi is difficult to assign to either clade due to many intermediate or plesiomorphic electrophoretic characters. Unlike the major karyologic and biochemical separation that divides Afrotropical and Palaearctic species, the subdivision between Palaearctic and Indomalayan Crocidura is not correlated with any trend in karyotypic evolution. It also is shown that the Eurasiatic species of Crocidura possessing 2n = 40 chromosomes (including C. dsinezumi) do not represent a particular clade, but probably share a plesiomorphic character. Further analysis of other Indian or Asiatic species is needed to test whether the Palaearctic versus Indomalayan separation is due to real zoogeographic barriers or whether it is the result of limited samples.

La passió segons Renée Vivien i el miratge-miracle del mirall

In this article, Rosa Cabré discusses Marçal¿s novel and illustrates how, according to the author, the desire of love, which is a source of pleasure often accompanied by guilt and distress, can lead to the creation or the illusion of an absolute beauty, like poetry. She explains in what way the mirror and the mask, recurring motifs in Marçal¿s work, symbolise identity and ¿otherness¿ and how these unite the real and the symbolic level. The novel contains an infinite number of mirrors, both external and internal ones, which enable the characters to see themselves reflected. This reflection is linked to feminity and to the possibilities of discovering one¿s own identity.

La mujer que no es sólo metáfora de la nación

En este artículo se ofrece una lectura de las viudas de vivos de Rosalía de Castro como una metáfora compleja de la nación y nada complaciente con los relatos nacionales estereotipados del XIX. Frente a lecturas que han confinado a la viuda en el estereotipo de nación sufriente por la emigración, siguiendo la lectura del libro completo la viuda de vivo se muestra una representación femenina no prevista ni en los discursos de la nación ni de la vindicación del XIX.

Differential vegetative and reproductive performances among fifteen guinea grass hybrids

The main scope of this work was to detect (Panicum maximum Jacq.) genotype differences as to morphoagronomic and seed quality indices, and to establish character correlations useful for determining vegetative and reproductive trends. Besides the flowering cycle, eight phenological and two seed quality traits were scored in a greenhouse randomized complete block experiment, as follows: plant height (PH), reproductive tiller number/overall tiller number (RTN/OTN), panicle number/reproductive tillers (PN/RT), leaf length (LL), leaf width (LW), panicle length (PL), fresh weight (FW), dry weight (DW), number of seeds/g (NS/G) and seed sample physical purity (SPP). Very-early and early-flowering hybrids consistently showed the highest correlation values among flowering cycle and RTN/OTN (r = -0.59**), PN/RT (r = -0.48**), NS/G (r = -0.88**) and SPP (r = -0.80**) (reproductive parameters) while intermediate and late-flowering hybrids presented the highest values for LL (r = 0.53**), LW (r = 0.60**), PL (r = 0.77**), FW (r = 0.78**) and DW (r = 0.85**) (vegetative traits). The implications of these results for plant breeding and forage management purposes are discussed.

Description of a pure seed fraction of oat through usual evaluations and radiographic images

The objective of this work was to evaluate the width and length incidence in a single seed fraction of oat [Avena sativa (L.)] cv. Cristal. The seeds were selected by a mechanical divider and by hand, and their correspondence to radiographic images in seeds with glumes and their caryopses. The width and length of the seeds with glumes and their caryopses were measured with electronic calliper, and their weight, with precision balance. Radiographic images of seeds with glumes were taken with an X-ray experimental equipment. The analyst selected seeds with glumes by the width and by the length previously determined and so with more weight, than that obtained by hand selection was slightly narrower, larger and lighter. The presence of the glumes masked the caryopses real dimensions (width and length), and conduced the analyst to select seeds that differed more by the width than by the length. The radiographic images showed the presence, or not, of caryopses inside the seed and its real dimensions. The mechanical partition method for seeds showed to be more efficient because the analyst subjectivity was not considered when the selection upon its dimensions was done. The X-ray analysis was a useful tool that complements the pure seed fraction selection as another factor of seed quality.

Diallel analysis for frogeye leaf spot resistance in soybean

Seven soybean cultivars (Bossier, Cristalina, Davis, Kent, Lincoln, Paraná and Uberaba), with different levels of resistance to Cercospora sojina, were crossed in a diallel design to determine the general (GCA) and specific (SCA) combining abilities relative to the inheritance of the resistance. Race 04 of the fungus was inoculated in the parents and in the 21 F1 hybrids in a greenhouse in a completely randomized design, with 12 replications. The reactions to the disease were evaluated 20 days after the inoculation, always on the most infected leaflet. Both GCA and SCA were significant for all the evaluated characters, being inferred that, for the expression of the characters, the additive, dominant and, possibly, epistatic genic actions were important. The largest values of estimated SCA effect (ij) were observed in the hybrid combinations where at least one parent presented high GCA. Cristalina, Davis and Uberaba cultivars showed the largest estimates for GCA effect (i), and from the analysis of ii, the contribution of these parents to heterosis of their hybrids will be towards the reduction of the disease symptoms. Therefore, these cultivars are indicated as parents in breeding programs that seek the development of soybean cultivars with resistance to frogeye leaf spot.

Agronomic performance of quinoa selected in the Brazilian Savannah

Twenty six breeding lines, selected from individual plant progenies of hybrids among varieties Amarilla de Marangani, Blanca de Junín, Chewecca, Faro 4, Improved Baer, Kancolla, Real, and Salares-Roja, had their agronomic characters evaluated, in Planaltina, DF, Brazil (15º36'S and 47º12'W), 1,000 masl, in randomized complete blocks, on a Ferralsol, previously limed and fertilized. Grain yield was positively associated with plant height, inflorescence length and diameter, and plant cycle. Genetic gain can be attained by selection based in these characters for commercial production of quinoa in tropical regions.

Maria-Mercè Marçal en el mirall : sobre l'imaginari femení i el llenguatge poètic

Per Maria-Mercè Marçal, la poeta no es pot trobar, no es pot veure, en el «mirall del bell», que sempre han fomentat els discursos dominants. El seu és una altra mena de mirall trencat que reflecteix un ésser complex, híbrid i contaminat que lluita «entre un jo que es vol fer i els múltiples personatges que, des del mirall, li retornen una imatge múltiple». En aquest article, per explorar el tema de l’imaginari femení i el llenguatge poètic, hem escollit dialogar amb Maria- Mercè Marçal i examinar tres dels múltiples bocins que conformen la seva imatge en el mirall. Conversem amb dues mares i un pare simbòlics de l’altre cantó del seu espill, tots tres proveïdors de material ideològic i eixos vertebradors dels assaigs marçalians. Es tracta d’intel·lectuals ben diversos: l’escriptora anglesa Virginia Woolf, el filòsof francès Jacques Derrida i la poeta catalana Maria-Antònia Salvà. En definitiva, dividim la investigació en tres apartats, que volen coincidir amb el diàleg que Marçal suposem que hi mantingué. De primer, amb Virginia Woolf, explorem la necessitat de la poeta de descobrir el sentiment de «fúria» que porta a dins per tal d’assumir la irracionalitat del seu llenguatge. Després, ens endinsem en les teories derridianes sobre la dona i l’escriptura, en un intent de demostrar que ambdues són espècies híbrides que viuen en el llindar, en un espai d’entremig. A l’últim, amb Maria-Antònia Salvà, revisem la imatge de la dona-monstre amb la certesa que «el salvatge» i «l’incert » són el motor del llenguatge poètic femení.

Le bon vin d’Orleans, le punays lac de Sorbone et la mode de Bretaigne: sociocentrisme lúdic i ambivalència als blasons populars del Pantagruel de Rabelais, amb mostres de versions en diferents llengües

En aquest article es presenta una selecció d’un corpus extret del Pantagruel, en el qual els personatges de Rabelais ataquen o afalaguen, grotescament i hiperbòlica, en el més pur estil pantagruèlic, les altres nacions o viles. Per a aquests epítets ètnics, Rabelais reutilitza el blasó popular (blason populaire), en una fusió total de la lloança i la injúria. En el nostre treball comprovarem si la visió sociocèntrica que el blasonador aplica al blasonat, així com el propòsit lúdic, han aconseguit ser traslladats a les versions catalana (Miquel-Àngel Sánchez Férriz, 1985), espanyola (Alicia Yllera, 2003), italiana (Mario Bonfantini, 1953) i anglesa (Burton Raffel, 1991).

Patriarchal Hauntings: Re-reading Villainy and Gender in Daphne du Maurier's Rebecca

Criticism of Daphne du Maurier’s popular classic Rebecca (1938) can be divided into two mainstream interpretations. On the one hand, it was traditionally marketed as a gothic romance where the hero and the heroine conquered the evil women that separated them. On the other, certain feminist critics have recently provided a very diff erent view of the story, aligning it with gothic narratives that deal with the dangers women suff er under the patriarchal control of their husbands. Th is would imply that du Maurier’s novel should not be read as a traditional romance that promotes patriarchy, as the former interpretation suggested. In this article, I propose, through a Gothic Studies and a Gender Studies reading, that villainy in this novel is not exclusively linked to gender and, therefore, the victim and abuser statuses cannot be equated to femininity and masculinity, respectively. Instead, I argue that villainy in the novel is inextricably connected to being in a powerful position within patriarchy, and that it is the desire to maintain this position and perpetuate the patriarchal system that leads the main characters (men and women) to commit acts of villainy.
