Short summary

The origin of N which contributes to N reserves of trees in autumn and to the growth of new organs the following spring is currently poorly documented. The metabolism of various possible N sources (plant and soil) was characterized in sessile oaks. Results revealed that in autumn, roots’ N reserves were formed from foliage N and to a lesser extent from soil N. The following spring, N used for the synthesis of new leaves came first from stored N and thereafter from N uptake from soil.
