Diversidade genética em coleções amazônicas de germoplasma de cupuaçuzeiro [Theobroma grandiflorum (Willd. ex Spreng.) Schum.]

This study aimed to evaluate the genetic diversity and relatedness of 24 accessions of Theobroma grandiflorum, originating from three units of Embrapa, aiming their use as parents in hybridization specie programs. The genetic markers used were heterologous microsatellite loci developed for cocoa. In the population studied 45 alleles were found. The effective average number of alleles per locus (2.33) was less than the average number of alleles per locus (3.21), indicating that many alleles have low frequency. The observed heterozygosity at polymorphic loci ranged from 0.33 to 1.00 with a mean of 0.54 and expected heterozygosity ranged from 0.48 to 0.76 with a mean of 0.54. The fixation index medium between loci (0.003) was not significantly different from zero. The estimate of relatedness between pairs of individuals indicates that some may be relatives, including half-brothers and clones. The results suggest that the accesses of T. grandiflorum analyzed contain a moderate level of genetic diversity and absence of inbreeding and therefore great potential for use in breeding programs.

Seleção de progênies de nabo-forrageiro para germinação sob altas temperaturas

Due to the expansion of the wild crop to regions with higher temperatures is important to develop cultivars adapted to high heat. The aim was to select tests for evaluating seed physiological quality of wild radish to estimating genetic characters in order to select cultivars adapted to high temperature conditions. Hundred of half-brothers of wild radish were subjected to germination test and vigor (first count of germination, classification of seedling vigor, accelerated aging test, germination and testing of the first count at high temperature as well as seedling emergence in field. The germination test, first count test, accelerated aging and high germination test (20-35°C) can be used for the selection of wild radish crop populations adapted to germination and field emergence under high temperatures.

Testes para a seleção de populações de cenoura visando ao vigor e à longevidade das sementes

Populations of carrot seeds with superior physiological quality and storage potential are of interest to seed companies and growers. Thus, we verified the efficiency of some tests for the selection of carrot populations with greater vigor and longevity of seeds. Seeds of 50 carrots progenies of different half-brothers from Brasilia cultivar were evaluated for the mass of one hundred seeds, the first count, germination, dormancy, accelerated aging with water and saturated NaCl solution. The seeds were stored at moisture contents of 6.1±0.3% in hermetic packaging at temperatures of 15 and 25°C for 12 months and germination was evaluated quarterly. The experimental data were evaluated for variance and phenotypic, genotypic and environmental heritability, coefficient of variation and genetic gain from selection. Selection based on the mass should not be used because it would increase the occurrence of dormancy in seeds of the next generation. The test of the first count, germination and accelerated aging in water or saline solution saturated may be used to select populations of carrot seeds of higher vigor and longevity. The estimated gain genetic selection for germination after 12 months storage at 25°C was 14%.

Contos de fadas: recurso educativo para crianças com deficiência intelectual

Studies show the psychological contribution of fairy tales regarding the child's development as one of the best plumbers of existential problems, appeasing it by acting as an outlet for their anguish, anxieties, and fears, engendering greater emotional balance. Thus, through researches in the literature, it was established as objective to seek information about the functionality of the fairy tales in the educational process of students with intellectual disabilities who presents challenging behaviors. Among the tales, the Brothers Grimm are suggested to be used as an educational resource. It was possible to say that, through the symbolic mediation in the imaginary of children with intellectual disabilities, educational work with fairy tales evokes significant benefits.

Gestão ambiental na produção avícola: estudo de caso

The present study addresses the application of the Environmental Management System in chicken production on a farm owned by the Nardo brothers, located in the city of Guapiaçu/SP (Brazil). The objectives were to analyze the process of solid waste generation, destination and forms of treatment in this activity; propose measures to reduce the use of potable water for non-potable ends; determine other measures identified through a questionnaire drafted by Embrapa (Brazilian Agriculture Research Cooperative) and administered to employees who have direct involvement in the productive process; pay visits to chicken production enterprises; and employ the guidelines proposed by the National Fowl-Breeding Sanitation Program that guide the application of the Environmental Management System. Adequate management of waste was put into effect through the construction of a compost shed capable of meeting current production demands, in which all procedures were accompanied – from civil construction to the commercialization process of the organic fertilizer generated. The rain-gathering system for the roofs of the pens proposed to reduce the consumption of potable ground water destined for washing the floors of the pens was completely dimensioned and budgeted, allowing the motivated owners to place the project into effect in a timely fashion. Other simpler but no less important proposals were also made in order to bring the production up to the required quality standards.

A importância dos contos de fadas originais no desenvolvimento infantil: um incentivo ao raciocínio lógico

Fairy tales are popular stories that has been narrated for centuries, whether through oral tradition or printed manuscripts, over generations. It is known that fairy tales can, through symbolism, to penetrate the human unconscious, rescuing emotions, feelings and influencing their actions and ways of thinking, and are means of transmitting moral values propagated by particular historical and social contexts for variations that appear in the same story, because it can be modified by the intention of the person who transmits me story and the interpretation of those who read it, at a particular time and situation. Although, these changes, compared to the classic fairy tales of Perrault, the Grimm Brothers and Andersen, are marked clearly different, which shows the habits and customs of the time in which they are conveyed, whether in written or oral form. The present work aimed to study the differences between current and classic tales, as well as their influences on implications for the child's mind, from a work by the teacher, which consider the role of context in the situation, the characters and the plot. Thus it is intended that students be induced to question, to understand the values dealtturn in the story and to make inferences, and that logical reasoning be stimulated not only for reading, but for any act of communication to occur

Memória e identidade nos romances de Milton Hatoum

This article deals with how Milton Hatoum explores aspects of the memory, through the convergence of voices in his four Lusophone novels Tale of a Certain Orient, The Brothers, Ashes of the Amazon and Orphans of Eldorado. A profile of complex characters is constructed through a synthesis of accounts, letters and depositions, as different faces of individuals and society at large are interspersed through memory.

Photomorphogenic modulation of water stress in tomato (Solanum lycopersicum L.): the role of phytochromes A, B1, and B2

Phytochromes are red/far-red light photoreceptors that mediate a variety of photomorphogenic processes in plants, from germination to flowering. In addition, there is evidence that phytochromes are also part of the stress signalling response, especially in response to water deficit stress, which is the major abiotic factor limiting plant growth and crop productivity worldwide. In this study, we used the phyA (far red-insensitive; fri), phyB1 (temporary red-insensitive; tri) and phyB2 mutants of tomato (Solanum lycopersicum L.) to study the roles of these three phytochromes in drought stress responses. Compared to wild type (WT) plants grown under water-deficit stress conditions, the fri, tri, and phyB2 mutants did not exhibit altered dry weights, leaf areas, stomatal densities, or stomatal opening. The stomatal conductance of all three mutants was severely reduced under both fully-hydrated and water-deficit conditions. Although relative water contents did change after drought stress in each mutant, the most significant reduction in water potential during water stress was observed in the fri mutant. However, this mutant returned its water status to WT levels during rehydration. Although the phyB2 mutant lost more water from detached leaves during abscisic acid (ABA) treatment, phyB2 behaved like WT plants, indicating that this mutant was not insensitive to ABA. Overall, these results indicate that the phytochromes phyA, phyB1, and phyB2 modulate drought stress responses in tomato.

As crianças protagonistas dos contos de fadas dos Irmãos Grimm

The origins of the fairy tales are lost in the past but these tales are, even today, great teaching instruments because they relate to language development, creativity, social relations, and especially with the internalization of values and behavior patterns. According to Bettelheim (1980), fairy tales assure the children that the difficulties can be overcome, no matter how insignificant they feel. In this sense, these tales are power tools. We understand that fairy tales - and their characters - have the power to influence their readers/listeners. Therefore, this study considered four fairy tales in which the protagonists are children and remain as children all though the narratives: Little Red Riding Hood, Hansel and Gretel Snow White and Rose Red and Thumbling, from Grimm Tales, translated into Portuguese by David Jardim Junior and published in 2008 by Itatiaia. We sought investigate how the children characters of these stories act, leveraging a reflection grounded on the image of children that emerge from the selected tales - images that have been registered in the first decades of the nineteenth century by the Brothers Grimm in their Children's and Household Tales - enabling the identification of the kinds of behavior that they perform and the values they embody, thus contributing to a better understanding of the models that these characters offer to the twenty-first century's children. Our research has a qualitative approach of bibliographic nature, mainly grounded in the ideas of Bettelheim (1980) and Ariès (1981). We found that there is a shortage of studies on the tales collected/maintained by the Brothers Grimm, although these stories have become classics of universal children's literature and continue, cradling the imagination of Western children in the twenty-first century. We also verified that there are very few studies exploring the representation of children in fairy tales and children's literature...
