| Summary, etc. |
The growth of whole plants is dependent on tissue N concentration. Plants that grow in N?rich environments have higher internal N concentrations and a higher relative growth rate, as described by the N productivity concept. When supply of nitrate N is interrupted, growth is maintained from storage pools of unassimilated nitrate for a limited time. Plants with low N supply show low shoot growth, high root-shoot ratio and decreased leaf growth. N is allocated more to the uppermost leaves, where there is a higher requirement for photosynthetic enzymes and chlorophyll, and mobilized to seeds as the leaves senesce. In actively photosynthesizing leaves, N?containing primary metabolites are present in relatively constant concentrations, although concentrations of N?containing secondary metabolites are more variable. The acquisition of nitrate is largely dependent on mass flow across the soil, but acquisition of ammonium depends more on diffusion to the roots. In a crop, uptake over a growing season is regulated by plant demand. This demand is signalled from the shoots to the roots. Some adaptations of roots enable the acquisition of nitrogen before it is acquired by other plants, and species adapted to N?rich soils have high leaf N concentrations and high specific leaf area, and out?compete other species for light. Those plants with higher leaf N concentrations seem to be more susceptible to herbivory and attack by micro?organisms, however. |
