Abstract
THE high incidence of failure when late-successional conifer species are replanted on disturbed forest sites is a considerable problem1–3. Here we advance a hypothesis that might explain many of these reforestation problems on a physiological basis, within the framework of forest succession. It is known that the chemical speciation of inorganic nitrogen in forest soils changes from predominantly ammonium (NH+4) in late-successional (mature forest) soils to mostly nitrate (NO–3) after disturbances such as clearcut harvesting2–6. The capacity of plant roots to take up and use these two sources of nitrogen is therefore very important for species establishment on successionally different sites. We have used kinetic and compartmental-analysis techniques with the radiotracer 13N to compare the efficiency of nitrogen acquisition from NH+4 and NO–3 sources in seedlings of white spruce, an important late-successional conifer. We found that uptake of NH+4 was up to 20 times greater than that of NO–3 from equimolar solution, cytoplasmic concentration of NH+4 was up to 10 times greater than that of NO–3, and physiological processing of NO–3 was much less than that of NH+4. This reduced capacity to use NO–3 is thought to present a critical impediment to seedling establishment on disturbed sites, where species better adapted to NO-3 would have a significant competitive advantage.
