Good Practices in Strategic Environmental Assessment Processes under the Brazilian Practitioners’ Vision  [PDF]
Antonio W. L. da Silva, Marinilse Netto, Paulo Selig, Alexandre Lerípio
Journal of Environmental Protection (JEP) , 2018, DOI: 10.4236/jep.2018.96045
Abstract: The use of good practices (GP) can improve the technical quality and, as a consequence, the outcome of the Strategic Environmental Assessment (SEA) process, increasing its effectiveness. This study aimed to present GP pointed out by Brazilian practitioners (members of the SEA development teams) from the perspective afforded by their participation in processes of this tool. The data were collected through personal interviews with 11 professionals responsible for preparing a total of 17 SEAs, who were asked about what measures adopted in the SEA could be considered BP. The responses were audio-recorded, transcribed, and had their content assessed by Content Analysis technique. Nine GP were highlighted by practitioners. The GP indicated represent a valuable contribution to the improvement of future use of SEA, either in Brazil or in other countries, because they are the result of consolidated experience in real cases of application of the tool.

The coffee seeds are problematic for the physiologycal quality, featuring low speed of seedling emergence. In this sense, this work was developed with the objective of evaluating the effect of sodium hypochlorite in the removal of the parchment and in the emergence and seedlings development of conilon coffee in nursery conditions. Coffee seeds of the variety Victoria were used, which were harvested in the cherry stage and pulped by hand. Seeds were dried in an oven with forced ventilation until reaching moisture contents of 35%, 30% and 25% wet basis. Then, the seeds with parchment were soaked in a sodium hypochlorite solution with concentrations of 4%, 5%, 6% and 7% active chlorine for 3 and 6 hours. For each moisture content, two additional treatments were added consisting of seeds with parchment and seeds in which the structure was removed manually. The characteristics evaluated were: emergence speed index, total emergence, dry mass of the shoots and root system. Utilization of sodium hypochlorite promoted an acceleration in seedling emergence speed similar to the method for manual removal of the parchment when using concentrations of 4%, 5%, 6% and 7% for 3 hours, at all moisture contents.

American Journal of Plant Sciences (AJPS) , 2014, DOI: 10.4236/ajps.2014.520314
Abstract: The selection of superior genotypes based on the simultaneous response to several characteristics of agronomic importance is a key strategy to overcome the scarcity of available varieties of papaya. This study aimed to apply the combined selection by using distinct selection indexes based on both the genetic values obtained by the REML/BLUP methodology and the real measured values to select agronomically superior genotypes of papaya within backcross progenies. The combined selection was carried out based on genetic and phenotypic values, original and standardized, multiplied by the agronomic weights. The results of the analysis of genetic parameters indicate that the evaluated progenies have expressive genetic variability for the considered traits, and that there are real possibilities of genetic progress with the selection. Among the analyzed indexes, the one based on standardized genetic value presented greater consistency in the ranking of genetic material, demonstrating the advantage of data standardization. Five progenies belonging to the BC1 generation, and five to the BC3 generation were selected using this index. A total of 27 plants ag-ronomically superior were selected within the top five progenies and recommended for generation advance, 23 being selected by combined selection and 4 using the direct selection for the four mainly characters in papaya breeding program: production, pulp and fruit firmness and soluble solids. Beyond the selection of superior genotypes for the development of future inbred lines, this study also allowed defining the best strategy to apply the combined selection in papaya using pre-dicted breeding values obtained by BLUP. This strategy may allow higher accuracy in the selection process, thus increasing the chances of success of the breeding programs.

Tavares, Rulfe;Viana, Alexandre Pio;Barroso, Deborah Guerra;Amaral Júnior, Antonio Teixeira do;
Ciência e Agrotecnologia , 2012, DOI: 10.1590/S1413-70542012000200005
Abstract: the increasing demand for raw material for multiple uses of forest products and by-products has attracted the interest for fast growing species, such as the australian cedar (toona ciliata), which presents high productive and economic potential. the present work aimed at estimating genetic diversity by dna markers and morphological traits supported for the mixed models. the following traits were measured and genotypes were sampled randomly in different areas: diameter at breast height, height, cylindrical volume, diameter, distance between nodes and crown diameter. twelve rapd primers were used and generated a total of 91 marks, 82 of which were polymorphic. the high percentage of polymorphic markers, 90.10%, demonstrated that discrimination in this species is efficient, but it yet little studied, for this case we can find the extent of the genetic basis for the application of technical improvement. the assessment of genetic diversity by the upgma method using the binary and morphological data provided the expression of genetic dissimilarities among the accessions evaluated, optimizing the perception of this divergence. the use of mixed models was efficient to assess combined genetic diversity to optimize the selection of genotypes with divergent genetic values for diameter at breast height.
