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.

What Do Cattle Prefer in a Tropical Climate： Water Immersion or Artificial Shade？

引用

Journal of Life Sciences 2012年第12期6卷 1356-1362页

作者： Ana Carina Alves Pereira de Mira geraldo Alfredo Manuel Franco Pereira Cristiane Gonqalves Titto Evaldo antonio Lencioni Titto Animal Science and Food Engineering Faculty University of Sao Paulo Pirassununga 13635-900 Brazil Institute of Mediterranean Agricultural and Environmental Sciences University of Evora Evora 7000 Portugal

Animal performance is affected by high air temperature and it is known that shade reduces the absorption of radiant temperature, and water for immersion facilitates heat loss. This study intends to find preferences of resources that contribute for the well-being of cattle and how they alterdaily behaviour. During summer, six Caracu and six Red Angus bulls were submitted to two different treatments： availability of artificial shade and water for immersion and availability of water for immersion. The categories observed were： positions （in the sun, under the shade, in the water）, posture （standing, lying down） and activities （grazing, ruminating leisure）. The behavioural patterns were recorded using the focal sampling method every 15 minutes （from 6：00 a.m. to 6：00 p.m.）. When shade and water for immersion coexists, cattle in this study prefer shade to avoid solar radiation. Both breeds had remained more time grazing, followed by ruminating in the Caracu breed, and by resting in the Red Angus breed. The Caracu breed had presented clear preference for the shade resource, but that fact was not always observed in the Red Angus breed. In hot climates, resources for defence against heat load, as shade and water for immersion improve the well-being of cattle.

Background: With population aging occurring worldwide, promoting climacteric women’s health has become the object of important studies. Purpose: Observing the prevalence of depression in climacteric women and their self-evaluation of the depression factors is the main goal of this study. Design: This cross-sectional research is enquiry descriptive. Methods: The sample was composed of 48 climacteric women (between 45 and 65 years old) non-selected volunteers, served by the Centers for Psycho and Social Attention (CAPS) of Specialized Mental Medicine, in Sorocaba, via the Beck Depression Inventory (BDI) questionnaire. Results: Checking the mean and frequency distribution, the climacteric women presented a prevalence of 37.5% of moderate depression (BDIindex = 24.39 ± 3.13), and 47.92% of severe depression (BDIindex = 38.13 ± 6.78). Concerning the symptoms, Spearman rank order correlation was found as the highest concerns, hierarchically: indecision (r = 0.72, p Conclusions: The prevalence of depression in these CAPS climacteric women was considered very high (86% ranking from moderate to severe) caused mostly by indecision, anhedonia, guilt, crying and self-esteem, followed by inutility, self-criticism and loss of concentration.

The objective of this paper relies on the establishment of the sampling moment and the nutritional state of the species Conilon coffee （Coffea canephora） cultivated in Cambisoils. The effect of different rates of nitrogen fertilization was also studied in the leaves concentrations of N, at randomized complete block designs （N0= 0; N1 = 50; N2 = 100; N3 = 150 and N4 = 200 ***^-1 of N） in presence of P （40 ***^-1 of P2O5） and K （160 ***^-1 of K2O）, with four replicates. The samples were carried out in the months of March （flower blossoming stage）, June （fruits growing stage）, September （grain development） and December （maturation） in all treatments. Foliar analysis carried out in the month of June （fruits growing stage） for the purpose of establishing critical nutrient range values for N, settling down approaches of interpretation of the same one for the Conilon coffee plantations on Cambisoils. The biggest percentages in the yields are obtained with leaves containing N between 2.80% and 3.10%, a value below 2.80% N which they associated with indicative percentages of stable maximum yield that did not surpass the limits of the adequate nutrients supply.

The Schinus terebinthifolius Raddi is a native plant of South America popularly known in Brazil as aroeira. It is a medium-sized plant, which demonstrates a high adaptive potential in various environments, besides having various medicinal properties such as anti-inflammatory and antidiarrheal. Bacterial susceptibility tests were carried out and the minimal inhibitory concentration (MIC) was obtained. The results were interpreted based on the conventionally microbiological protocols and data from the CLSI. For the microbiological tests, microorganisms obtained from the American Type Culture Collection (ATCC), specifically, (Pseudomonas aeruginosa, Staphylococcus aureus and Encherichia coli) were used. Of the tested bacterial strains, only the Staphylococcus aureus 6538 presented susceptibility to the aroeira’s hydroalcoholic extract, forming zones of inhibition of 8.0 mm of diameter up to the MIC of 35.3 mg/mL, while the other tested strains showed to be resistant in all the concentrations of hydroalcoholic extract of the Schinus terebinthifolius Raddi bark. Our aim is to analyze the “in vitro” antibacterial potential of the 70% hydroalcoholic extract of the Schinus terebinthifolius Raddi.

Elephant grass is a tropical forage plant widely spread in Brazil, used mainly in the livestock sector and in cattle feeding. Because of its high productivity and photosynthetic capacity, this culture has also been considered an alternative source of renewable energy. Six clones of elephant grass (Pennisetum purpureum Schum.) were evaluated under five levels of nitrogen fertilization (100, 200, 400, 800, and 1600 kg·N·ha-1), in a randomized-block design with a split-plot arrangement with three replicates, from April 2010 to December 2012, in the city of Campos dos Goytacazes— RJ, Brazil. The objective was to obtain estimates of variation in morpho-agronomic traits and biomass quality. We observed that genotypes Cameroon-Piracicaba and Gua?u I/Z2 have great potential to be used, with maximum dry matter yields of 60.97 and 44.10 t·ha-1 per cut for energy purposes among the studied genotypes.

This study estimates the environmental and socioeconomic impacts of coffee production in the agroforestry system in the settlements of farmers located in the West of the state of Silo Paulo, Brazil, in the region known as Pontal of Paranapanema, aiming at the development of programs to support the growth of production sustainable coffee and programs to protect the coffee activity before the possible global climate change. The settlements are located in areas with sandy soils and highly degraded by human action Moreover, the region is considered marginal for the production of coffee, because it is subject to periods of high temperatures, prolonged drought and frost risk, which hinders the sustainability of farms. The environmental and socioeconomic impacts of agroforestry are analyzed through Ambitec-agro system, consisting of a set of indicators aimed at ex-post evaluation of the contribution of technological innovation to environmental, social and economic development of an agricultural activity. The system Ambitec involves：（1） general data collection about the technology; （2） application of questionnaires with adopters selected and insertion of data on impact indicators spreadsheets via platform MS-Excel and to obtain quantitative results and impacts partial indexes and aggregates the impact of technology selected; （3） analysis and interpretation of indices obtained, which vary between -15 and 15. The results indicate that agroforestry management can contribute to：（1） maintaining or increasing the sustainability of traditional coffee-growing regions in the case of sudden climate change; （2） the expansion of the coffee regions now considered unsuitable for the cultivation of coffee; （3） for sustainable regional development.
