Potencial genético da população de milho UFV 7 para o melhoramento em Minas Gerais

Neste trabalho, objetivou-se avaliar o potencial genético da população de milho UFV 7 para o melhoramento em Minas Gerais. Foram instalados três experimentos com a população de milho UFV 7, em três regiões de Minas Gerais, na safra 2006/2007. Houve interação genótipos x ambientes para todos os caracteres. Foi verificada variabilidade genética para produtividade de grãos, altura de plantas e altura de espigas na população de milho UFV 7, nas três regiões. Na região Sudeste, a população de milho UFV 7 apresentou as maiores estimativas de parâmetros genéticos. A população UFV 7 apresentou alta produtividade de grãos, 9 112kg ha-1, no Sudeste, média produtividade, 6 510kg ha-1, no Oeste, e baixa, 4 572kg ha-1, na região Central. As estimativas de herdabilidade e CVg/CVe, para produtividade, foram superiores a 60% e 1,00, respectivamente. A produtividade de grãos teve correlação genética significativa e positiva com a altura de planta e altura de espiga, na região Oeste e na Central, e com a prolificidade na região Central e região Sudeste. Conclui-se que a população de milho UFV 7 apresenta potencial para extração de linhagens na região Central; potencial para uso imediato na região Sudeste e para novos ciclos de seleção na região Oeste de Minas Gerais, e a seleção para PG aumenta indiretamente a altura de planta e altura de espiga, nas regiões Oeste e Central.The objective was to assess the genetic potential of maize population UFV 7 for breeding in Minas Gerais, Brazil. Three experiments were installed with the maize population UFV 7 in the three regions of Minas Gerais, in the harvest of 2006/2007. There was genotype x environment interaction for all characters. It was observed genetic variability for grain yield, plant height and ear height in maize population UFV 7, in the three regions. The Southeast region was where the maize population UFV 7 had the highest parameters. The population UFV 7 presented high grain yield, 9 112kg ha-1 in the Southeast, average grain yield, 6 510kg ha-1 in the West and low, 4 572kg ha-1 in the Central Region. Heritability estimate and CVg / CVe for grain yield were higher than 60% and 1.00, respectively. Grain yield had significant and positive genetic correlation with plant height and ear height, in Western and Central, and the prolificacy in Central and Southeast. For maize population UFV 7 it was conclude that it has potential for extraction of lines in the Central Region; it has the potential for immediate use in the Southeast and for new cycles selection in the Western Region of Minas Gerais. The selection for PG provides an indirect increase in plant height and ear height, in the West and Central

A Multicountry Perspective on Cultural Competence Among Baccalaureate Nursing Students

Purpose: To assess cultural competence among nursing students from nine countries to provide an international perspective on cultural competence. Design: A descriptive, cross-sectional design. Methods: A convenience sample of 2,163 nursing students from nine countries was surveyed using the Cultural Capacity Scale from April to November 2016. Results: The study found a moderate range of cultural competence among the students. The ability to teach and guide other nursing colleagues to display culturally appropriate behavior received the highest competence rating, while the ability to discuss differences between the client's health beliefs or behaviors and nursing knowledge with each client received the lowest competence rating. Differences in cultural competence were observed between students from different countries. Country of residence, gender, age, year of study, attendance at cultural-related training, the experience of taking care of patients from culturally diverse backgrounds and patients belonging to special population groups, and living in a multicultural environment were identified as factors affecting cultural competence. Conclusions: The international perspective of cultural competence among nursing students provided by this study serves as a vital preview of where nursing education currently stands in terms of providing the necessary preparatory competence in the cultural aspect of care. The variation of cultural competence among nursing students from different nations should serve as a cue for designing a focused yet multimodal nursing education program in guiding them to be culturally sensitive, culturally adaptive, and culturally motivated. Clinical Relevance: The training of nursing students in providing competent culturally appropriate care should be ensured considering that adequate preparation of nursing students guarantees future competent nursing practice, which can positively impact the nursing profession in any part of the globe. © 2017 Sigma Theta Tau InternationalUniversidad Autónoma de Chil

Factor analysis and SREG GGE biplot for the genotype × environment interaction stratification in maize Análise de fatores e SREG GGE biplot para a estratificação da interação genótipos × ambientes em milho

The objective of this study was to evaluate the use of SREG GGE biplot methodology and factor analysis to stratify the genotype&times;environment interaction in maize. Forty-nine early maize hybrids were evaluated in nine environments. The experimental design used was a 7&times;7 square lattice with two replicates. Each plot consisted of two 5m long rows spaced 0.90m apart. Grain yield data were used to perform the analysis. The results indicated the existence of two mega-environments in the State of Minas Gerais, Brazil, for early maize hybrids. The stratification of the environment by factor analysis was more selective to join the similarity the according with cultivar performance. However, this approach did not identify specific genotype x environment interactions, which is possible through SREG GGE biplot analysis.<br>O objetivo deste estudo foi avaliar a metodologia SREG GGE biplot e a análise de fatores na estratificação da interação genótipos&times;ambientes em milho. Foram avaliados 49 híbridos comerciais de milho de ciclo precoce em nove ambientes. Foi utilizado o delineamento látice quadrado 7&times;7, com duas repetições. Cada parcela consistiu de duas linhas de 5m espaçadas por 0,90m. Para a realização das análises, foram utilizados dados de produtividade de grãos. Os resultados indicaram a existência de dois mega-ambientes no Estado de Minas Gerais para híbridos de milho de ciclo precoce. A estratificação de ambientes pela análise de fatores mostrou-se mais seletiva em reunir ambientes pela similaridade de desempenho dos cultivares, mas não evidenciou as interações genótipos x ambientes específicas, o que foi possível pela análise SREG GGE biplot

Brotações adventícias de abacaxizeiro ornamental sob o efeito de benzilaminopurina, ácido naftalenoacético e períodos de subcultivo Adventitious shoot of ornamental pineapple under benzylaminopurine, naphthalene acetic acid and subculture period effect

O objetivo deste trabalho foi avaliar os efeitos da adição de benzilaminopurina (BAP), em combinação com o ácido naftalenoacético (ANA), e dos períodos de subcultivo, na formação de brotações in vitro de abacaxizeiro ornamental. O meio básico líquido consistiu de sais minerais MS e vitaminas. O delineamento experimental utilizado foi o inteiramente casualizado, em esquema fatorial 6x2x4, com seis concentrações de BAP (0, 0,125, 0,25, 0,5, 1 e 2 mg L-1) e duas de ANA (0 e 0,1 mg L-1), e quatro períodos de subcultivo (30, 60, 90 e 120 dias). Os explantes consistiram de brotações individuais de 1 cm de comprimento, oriundas da cultura in vitro. A formação de novas brotações foi observada em meio suplementado com BAP, em todos os períodos de subcultivo. O maior número médio de brotos por explante foi obtido em meio com a concentração de 1,2 mg L-1 de BAP e 120 dias de subcultivo.<br>The objective of this work was to evaluate the effect of benzylaminopurine (BAP) additions, in combination with naphthaleneacetic acid (NAA), and of subcultures periods on in vitro shoot formation of ornamental pineapple. The basal liquid medium consisted of MS salts and vitamins. The experiment was a completely randomized design, in a factorial arrangement 6x2x4, with six concentrations of BAP (0, 0.125, 0.25, 0.5, 1, e 2 mg L-1) and two of NAA (0 and 0.1 mg L-1), and four subculturing periods (30, 60, 90 e 120 days). The explants consisted of individualized shoots with 1 cm length from in vitro cultures. Shoot formation was observed in medium supplemented with BAP in all subculturing periods. The greatest average number of shoots per explant was obtained with BAP concentration of 1.2 mg L-1 and 120 days of subcultive
