| Realizou-se, em Planaltina (DF), nos anos agrícolas 1995/96, 1996/97 e 1997/98, um experimento num Latossolo Vermelho-Amarelo franco-argilo-arenoso, para comparar o efeito de três métodos de aplicação de cobre (ao solo, em pulverização foliar e à semente) sobre a produção de soja (cv. Doko RC) e estabelecer níveis críticos para os teores de cobre no solo e na folha. No primeiro cultivo, não houve diferença significativa entre os tratamentos provavelmente pela ocorrência de déficit hídrico (veranico) na fase de enchimento de grãos. No segundo e no terceiro cultivo, as doses de 1,2 e 2,4 kg ha-1 de cobre aplicadas a lanço apenas por ocasião do primeiro cultivo ou no sulco de semeadura parceladamente, ou seja, 0,4 e 0,8 kg ha-1 de cobre por cultivo,... |

| Plant efficiency for phosphorus uptake and utilization may contribute to improve crop yield potential in situations of low P availability. Twenty nine soybean [Glycine max (L.) Merr.] cultivars were evaluated and classified in relation to the response to phosphorus (P) levels in nutrient solution. P uptake and use efficiency were estimated by the variables: shoot and root dry matter (DM) yield, P-concentrations and contents in plant parts and P-efficiency index (EI). The experiment was conducted in a greenhouse, during 1999, at Campinas, State of São Paulo, Brazil. The experimental design consisted of randomized complete blocks, arranged in split-plots, with three replications. The main plots were the P levels in the nutrient solution (64.5; 129; 258 and... |

| The flooded environment brings about injuries to soybeans that vary depending on the adaptation ability of the genotype. Oxygen deprivation promotes the induction of the expression of genes related to glycolysis and fermentation pathways to maintain energy metabolism and, in addition to reducing-power consuming processes, act in the formation of adaptive structures and the maintenance of the redox status of the plant. The aim of this work was to evaluate the relative expression of genes related to soil flooding response in two contrasting soybean cultivars. Soybean plants of the sensitive (BRS 154) and tolerant (I27) cultivars at the V1 development stage were submitted to the flooding and control conditions (without flooding) for 0, 24, 48, and 96 hours.... |

| Foram realizados dois experimentos em um delineamento em blocos ao acaso com três repetições, em Cristalina (GO), na safra de 2005/2006, para avaliar a reação de genótipos de soja convencional e transgênica (RR) ao crestamento foliar causado por Cercospora kikuchii. No experimento 1, foram avaliados 86 genótipos de soja convencional e no experimento 2, 30 genótipos de soja convencional e transgênica quanto à reação ao crestamento foliar. Como padrões de genótipos convencionais foram usados Emgopa 313 e Msoy 8001 e como genótipos transgênicos Msoy 8585 RR e Msoy 8787 RR. Os genótipos com menor incidência (<1%) da doença no experimento 1 foram: GT04-7229, GT04-8987, GT04-8902, GT04-7991, GT04-8218, GT04-9501, GT04-7020, GT04-7505 e GT04-7439. No... |

| In this study, simple sequence repeats (SSR) loci and pedigree data were used to investigate the genetic relationship in a group of 168 Brazilian soybean cultivars. Eighteen SSR loci produced an average of 5.06 alleles and a mean gene diversity of 0.58 for the cultivars studied. Genetic distance (GD) was determined using the modified Roger's Wright distance, and a final dendrogram was in agreement with the cultivar pedigree. A distance matrix based on the coefficient of parentage scores was also generated for the cultivars, which ranged from 0 to 1, with a mean of 0.18, whereas SSR-based genetic similarity (1- GD) ranged from 0.01 to 0.90, with a mean of 0.25. Mantel's Z test showed that the similarity matrices generated from both the data sets were low,... |

| The scope of the present study was to investigate how the p-coumaric (p-CA) and p-hydroxybenzoic (p-HD) acids affect the peroxidase (POD, EC 1.11.1.7) activity, the lipid peroxidation (LP) and the root growth of soybean (Glycine max (L.) Merr.). Three-day-old seedlings were cultivated in nutrient solution containing p-CA or p-HD (0.1 to 1 mM) for 48 h. After uptake, both compounds (at 0.5 and 1 mM) decreased root length (RL), fresh weight (FW) and dry weight (DW) while increased soluble POD activity, cell wall (CW)-bound POD activity (with 1 mM p-CA and 0.5 mM p-HD) and LP. |

| ABSTRACT The aim of this study was to evaluate the effect of different seed coatings consisting of various combinations of three nutrients (calcium, magnesium and silicon) on two soybean cultivars (BRS 243 RR and CD 233 RR). Dolomitic limestone and aluminum silicate were chosen as the nutrient sources. Leaf area, plant height, shoots dry matter, crop growth rate, relative growth rate and net assimilation rate were the studied variables, evincing that the seed coating that comprised calcium, magnesium and silicon led to better performance in terms of growth rates 30 days after emergence. Significant differences in the response to the seed coatings were also observed between the two studied soybean genotypes. |

| A cobertura vegetal do solo é decisiva para redução dos efeitos erosivos do impacto direto das gotas de chuva na superfície do solo. Desta forma, objetivou-se com este estudo determinar o índice de cobertura vegetal (CV) e desenvolver modelos para sua estimativa para a cultura da soja, usando os atributos climáticos no período de chuvas intensas no Sul de Minas Gerais. As determinações da CV foram feitas semanalmente, na área experimental do Departamento de Ciência do Solo, Universidade Federal de Lavras, no período de novembro de 1999 a maio de 2000, em 28 cultivares de soja com potencial para cultivo nesta região. Para avaliação da cobertura vegetal foi utilizada a metodologia descrita por Stocking (1988). Na modelagem procurou-se relacionar a CV com os... |
