Relationships among nitrogen accumulation, nitrogen assimilation and plant growth in chrysanthemums
Physiologia Plantarum, 1983Relationships among growth, N accumulation and assimilation were investigated in Chrysanthemum morifolium Ramat cv. Fiesta in experiments testing the effects of varying levels of NO–33supply and of increasing NH+4 added to a constant level of NO–33 Flowing solution culture systems were used to provide NO−3at concentrations of 0.03 to 5.0 mol m–3 and NH+

Genomic regions governing soybean seed nitrogen accumulation
Journal of the American Oil Chemists' Society, 2004AbstractNitrogen accumulation in the form of seed protein takes place in soybean [Glycine max (L.) Merr.] during the reproductive stages of development. The purpose of this study was to relate genotypic differences in seed nitrogen accumulation with genomic regions controlling nitrogen accumulation in soybean during R5, R6, and R7 growth stages.

AbstractBACKGROUNDOzone (O3), a widespread air pollutant, significantly impairs crop growth and development, with wheat, the second largest crop by planting area of the world, being especially vulnerable. This study, conducted under Free Air Concentration Enrichment (FACE) conditions, focused on four wheat cultivars from the middle and lower reaches of

Monitoring nitrogen accumulation in mosses in central European forests
Environmental Pollution, 2008In order to assess whether nitrogen (N) loads in mosses reflect different land uses, 143 sites in North Rhine-Westphalia, the Weser-Ems Region and the Euro Region Nissa were sampled between 2000 and 2005. The data were analysed statistically with available surface information on land use and forest conditions.

Net anthropogenic nitrogen accumulation in the Beijing metropolitan region
Environmental Science and Pollution Research, 2010A rapid increase in anthropogenic nitrogen inputs has a strong impact on terrestrial and aquatic ecosystems. We have estimated net anthropogenic nitrogen accumulation (NANA) as an index of nitrogen (N) pollution potential in the Beijing metropolitan region, China.

Abstract The 15 N dilution technique was used to measure N 2 fixation by field-grown spring-sown leguminous grain crops over two seasons and autumn-sown leguminous forage crops over one season. Nitrogen balances for the various crops were also calculated.
