Soybeans generally are not considered a major source of lutein; however, concentrations of the chemical suggest that it could represent a dietary lutein source in some Asian countries, where soybeans are an important food crop. Increasing the lutein level in soybeans have now become a priority for some breeding programs.
Researchers at McGill University, the Centre de Recherche sur les Grains, and Agriculture and Agri-Food Canada in Quebec have studied the impact crop management practices and cultivar selection have on lutein concentrations in soybean grown in multiple environments.
Their study was funded by research grants from the Ministère de l’Agriculture, des Pêcheries, et de l’Alimentation du Québec (MAPAQ) and the Natural Sciences and Engineering Research Council of Canada (NSERC). Results from the study are published in the May-June 2011 issue of Crop Science.
Almost all crop management practices investigated affected soybean lutein concentrations in most of the environments. The seeding date had the greatest effect on concentrations of the chemical, with differences in lutein concentration averaging 41%. Seeding rate, row spacing, and fertilization effects were moderate, never exceeding an 8% difference between treatments. Scientists were able to identify soybean genotypes with high and stable lutein concentrations.
"This suggests that the selection and development of high lutein cultivars should be possible," said Philippe Seguin, McGill University professor and author of this study. Additionally, environmental factors and crop management practices should be considered in the production and use of soybean as a lutein source.
Research is ongoing to identify the specific factors that affect soybean lutein concentration. This research will could help expand the markets for soybean producers.

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
