A abertura relativa dos estomatos (ARE) do guaranazeiro foi avaliada pelo método da infiltração de líquidos de diferentes tensões e pelo prometro de difusão Delta MKII, constatando-se uma correlação significativa (r=0,895) entre os dois métodos. A ARE máxima foi atingida as 9 horas, persistindo ate as 11 horas, quando houve uma continua e sensível redução desses valores. A redução na ARE, a partir das 12 horas, deveu-se, provavelmente, a excessiva transpiração pelos tecidos foliares e a elevação da temperatura da folha, favorecendo o aumento da tensão do CO2 na camara subestomatica. Tomados em conjunto, estes resultados permitem concluir que e possível que o guaranazeiro se beneficie de níveis relativamente baixos de sombreamento principalmente em locais onde o déficit hídrico na planta seja acentuado por influencia de fatores climáticos como elevada temperatura e excessiva velocidade do vento. |

The aim of this study was to perform a Bayesian genomewide association study (GWAS) to identify genomic regions associated with growth traits in Hereford and Braford cattle, and to select Tag‐SNPs to represent these regions in low‐density panels useful for genomic predictions. In addition, we propose candidate genes through functional enrichment analysis associated with growth traits using Medical Subject Headings (MeSH). Phenotypic data from 126,290 animals and genotypes for 131 sires and 3,545 animals were used. The Tag‐SNPs were selected with BayesB (π = 0.995) method to compose low‐density panels. The number of Tag‐single nucleotide polymorphism (SNP) ranged between 79 and 103 SNP for the growth traits at weaning and between 78 and 100 SNP for the yearling growth traits. The average proportion of variance explained by Tag‐SNP with BayesA was 0.29, 0.23, 0.32 and 0.19 for birthweight (BW), weaning weight (WW205), yearling weight (YW550) and postweaning gain (PWG345), respectively. For Tag‐SNP with BayesA method accuracy values ranged from 0.13 to 0.30 for k‐means and from 0.30 to 0.65 for random clustering of animals to compose reference and validation groups. Although genomic prediction accuracies were higher with the full marker panel, predictions with low‐density panels retained on average 76% of the accuracy obtained with BayesB with full markers for growth traits. The MeSH analysis was able to translate genomic information providing biological meanings of more specific gene products related to the growth traits. The proposed Tag‐SNP panels may be useful for future fine mapping studies and for lower‐cost commercial genomic prediction applications.
