Nitrogen fixation and accumulation in sugarcane under nitrogen supply

Research on Crops, 2014
In order to investigate nitrogen fixation and accumulation in sugarcane under nitrogen supply, a barrel gravel culture was conducted in Guangxi province, the southwest China in 2012. The sugarcane varieties B 8 and ROC 22 were employed as the plant materials, which were inoculated either with or without endogenous nitrogen fixation bacteria at two ...

Nitrogen retention and partitioning at the initiation of lipid accumulation in nitrogen‐deficient algae

Journal of Phycology, 2014
Nitrogen (N) deficiency promotes lipid accumulation in many oleaginous algae, but we have a poor understanding of the associations between the initiation of lipid accumulation and algal N retention and partitioning. Here, we report on total cell N, five bulk pools of N in the cell (protein, free amino acids, DNA, RNA, chl), and lipids from N saturation

Pattern of cyanophycin accumulation in nitrogen-fixing and non-nitrogen-fixing cyanobacteria

Archives of Microbiology, 2001
The temporal and spatial accumulation of cyanophycin was studied in two unicellular strains of cyanobacteria, the diazotrophic Cyanothece sp. strain ATCC 51142 and the non-diazotrophic Synechocystis sp. strain PCC 6803. Biochemistry and electron microscopy were used to monitor the dynamics of cyanophycin accumulation under nitrogen-sufficient and ...

Mineralisation of newly accumulated nitrogen

2001
Since the 1950s, large amounts of nutrients (N, P and K) have been accumulated in German arable soils due to a surplus in the balance between the amounts of nutrients applied and those removed in crop harvest. In western Germany (the former FRG), a significant part (about 30–100 kg N ha−1 yr−1) of the surplus N (more than 100 kg N ha−1 yr−1 has been ...

Modeling plant nitrogen uptake and grain nitrogen accumulation in wheat

Field Crops Research, 2006
Grain nitrogen (N) concentration is one of the main quality parameters of wheat grains. Since few reports have quantified the processes of N accumulation in both grain and vegetative parts in wheat (Triticum aestivum L.), this study was undertaken to develop a dynamic model for simulating plant N uptake and grain N accumulation in wheat by focusing on ...

ACCUMULATION OF NITRATE IN SPINACH DEPENDING ON FORMS AND DOSES OF NITROGEN

Acta Horticulturae, 2012
Nitrogen, as one of the most important element of nutrition, has lots of specifics. Its adsorption by plants directly depends on its content in the soil, as well as from the form and doses of nitrogen fertilizers. Spinach belongs to the group of nitrophillic vegetables.
