Selection of sorghum hybrids grown under aluminum saturation [PDF]

Genetics and Molecular Research, 2014
The purpose of this study was to evaluate 165 hybrids derived from lines previously selected for aluminum (Al) tolerance. Nine check cultivars were used, eight commercial hybrids and one experimental hybrid. Hybrids were evaluated at three levels of Al saturation (0, 20 and 40% on average).

Performance of grain sorghum hybrids in soils with low and high aluminum saturation

Pesquisa Agropecuária Tropical, 2018
The presence of aluminum (Al3+) in acidic soils is one of the main causes of low crop yield, since it inhibits the root growth, thus affecting the nutrients and water uptake by plants.

Visualization of Aluminum Dust Flame Propagation in a Square-Section Tube

Chemical Engineering Transactions, 2018
Metallic dust explosion is a challenging research topic. One key point of investigation is the flame propagation velocity, which can be determined experimentally by direct visualization of the explosions.

An examination of the saturation microstructures achieved in ultrafine-grained metals processed by high-pressure torsion

Journal of Materials Research and Technology, 2014
Experiments were conducted on two commercial alloys, a Cu–0.1%Zr alloy and an Al-7075 aluminum alloy, to investigate the significance of the saturation microstructure which is achieved after processing by high-pressure torsion (HPT).

Correction of soil acidity in the subsurface of an oxisol with sandy loam texture under no-tillage Correção da acidez do solo em subsuperfície de um latossolo de textura franco-arenosa sob plantio direto

Revista Brasileira de Ciência do Solo, 2009
In Rio Grande do Sul State (RS), Southern Brazil, aluminum saturation in many areas under no-till system is high and base saturation low in the 0.10-0.20 m layer (subsurface), which may reduce the grain yield of annual crops.
