The role of carbon (C) and nitrogen (N) storage by trees will be discussed in terms of
uncoupling their growth from resource acquisition. There are profound differences between …

Plants have developed a variety of molecular strategies to use limiting nutrients with a
maximum efficiency. N assimilated into biomolecules can be released in the form of …

Internal cycling of nitrogen has been shown to be a major source of nitrogen used for the
seasonal growth of both evergreen and deciduous trees providing up to 90% of N used for …

summary During the vegetation period 1994, the nitrogen (N) composition and contents of
leaves, xylem sap and phloem exudates of twigs from a coniferous (Picea abies (L.) and a …

During the growing session of 1995, the total soluble non-protein nitrogen (TSNN)
composition and contents of mycorrhizal fine roots, xylem sap and phloem exudates of roots …

Studies of small trees growing in pots have established that individual amino acids or
amides are translocated in the xylem sap of a range of tree species following bud burst, as a …

Nitrogen is remobilized from storage for the growth of Malus domestica leaves each spring.
Seasonal patterns of N translocation in the xylem sap as a consequence of remobilization …

Prunus avium trees were grown in sand culture for one vegetative season with contrasting N
supplies, in order to precondition their N storage capacities. During the spring of the second …

Background Most terrestrial vascular plants can assimilate soil obtained NO3-in their root
and shoot. Scope Data from the literature are collated and analysed with respect to …

Seasonal patterns of N translocation in the xylem sap of Betula pendula were studied, to
determine whether specific amino acids were recovered in spring as a consequence of N …
