Environmental conditions affect crop yield, and water deficit has been highlighted by the negative impact on soybean grain production. Radicial growth in greater volume and depth can be an alternative to minimize losses caused by a lack of water. Therefore, knowledge of how soybean roots behave before the chemical, physical, and biological attributes of the soil can help establish managements that benefit in-depth root growth. The objective was to evaluate the growth of soybean roots in response to chemical, physical, and biological variations in the soil, in different soil locations and depths. Six experiments were conducted in different locations. Soil samples were collected every 5 cm of soil up to 60 cm of soil depth for chemical, physical, and biological analysis. The roots were collected every 5 cm deep up to 45 cm deep from the ground. The six sites presented unsatisfactory values of pH and organic matter, and resented phosphorus, potassium, and calcium at high concentrations in the first centimeters of soil depth. The total porosity of the soil was above 0.50 m3 m−3 , but the proportion of the volume of macropores, micropores, and cryptopores resulted in soils with resistance to penetration to the roots. Microbial biomass was higher on the soil surface when compared to deeper soil layers, however, the metabolic quotient was higher in soil depth, showing that microorganisms in depth have low ability to incorporate carbon into microbial biomass. Root growth occurred in a greater proportion in the first centimeters of soil-depth, possibly because the soil attributes that favor the root growth is concentrated on the soil surface.

A maior parte dos trabalhos voltados à cultura da banana avalia às características agronômicas e as físico-químicas do fruto. Entretanto, sabe-se a banana também é fonte de
polifenóis. De acordo com Faller & Fialho (2009), a fruta é a principal fonte de polifenóis consumida no Brasil, variando conforme a macrorregião, onde o teor médio de polifenóis
obtidos pelos autores para as bananas foi de 215,7 mg. 100 g-1. Os polifenóis constituem um grupo heterogêneo, composto de várias classes de substâncias com propriedade antioxidante (Vargas et al., 2008). Dentre essas classes, destacam-se os flavonóides. As ações fisiológicas exercidas pelos polifenóis já foram relacionadas à prevenção de doenças cardiovasculares, neurodegenerativas, câncer, entre outras, principalmente em função da elevada capacidade antioxidante (Scalbert et al., 2005). Como esses compostos não podem ser sintetizados pelo nosso organismo, sendo representativos da parte energética da dieta humana, são obtidos por meio da ingestão de alimentos que os contenham ou através de suplementos nutritivos (Silva, 2010). |
