The Accumulation and Storage of Nitrogen by Herbaceous Plants

Plant, Cell and Environment, 1988
Abstract Accumulation of nitrogen (N) by plants in response to N supply outstripping demand is contrasted with storage of N, which implies that N in one tissue can be reused for the growth or maintenance of another. Storage can, therefore, occur in N‐deficient plants; accumulation can not.

Interactive Effect of Sulfur and Nitrogen on Nitrogen Accumulation and Harvest in Oilseed Crops Differing in Nitrogen Assimilation Potential

Journal of Plant Nutrition, 2008
Field experiments were conducted to determine the interactive effect of sulfur (S) and nitrogen (N) on nitrogen accumulation, its distribution in various plant parts, and nitrogen harvest of oilseed crops viz. rapeseed (Brassica campestris L.

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.

Effects of Nitrogen Forms on Carbon and Nitrogen Accumulation in Tomato Seedling

Agricultural Sciences in China, 2008
Abstract Utilization of organic nitrogen (N) is an important aspect of plant N assimilation and has potential application in sustainable agriculture. The aim of this study was to investigate the plant growth, C and N accumulation in leaves and roots of tomato seedlings in response to inorganic (NH4+-N, NO3−-N) and organic nitrogen (Gly-N).

Plant Nitrogen Accumulation Dynamics in Rice in Response to Nitrogen Management

Communications in Soil Science and Plant Analysis, 2010
This study investigates the effect of rice nitrogen (N) management on the dynamics of plant nitrogen accumulation (PNA) during internodal elongation (IE) in relation to grain yield. Four field experiments were conducted in two soils with six preflood N treatments. The PNA was monitored for 3 weeks, starting at the beginning of IE (BIE).

Nitrogen Accumulation and Residual Effects of Nitrogen Catch Crops

Acta Agriculturae Scandinavica, 1991
The nitrogen accumulation in Italian ryegrass (Lolium multiflorum Lam.), perennial ryegrass (Lolium perenne L.), white mustard (Sinapis alba L.) and tansy phacelia (Phacelia tanacetifolia L.), unde...
