A coordinated supply of the whole plant with sulfur (S) and nitrogen (N) requires
mechanisms to regulate not only uptake and assimilation but also long-distance transport of …

Xylem sap from woody species in the wet/dry tropics of northern Australia was analyzed for
N compounds. At the peak of the dry season, arginine was the main N compound in sap of …

During the growing season of the exceptionally dry and warm year 2003, we assessed
seasonal changes in nitrogen, carbon and water balance related parameters of mature …

To assess the physiological performance of drought-sensitive European beech (Fagus
sylvatica L.) under the dry Mediterranean climate prevailing at its southeastern distribution …

Ammonia (NH 3) fluxes between beech leaves (Fagus sylvatica) and the atmosphere were
investigated in a 90-year-old forest canopy and related to leaf nitrogen (N) pools and …

Abstract Knowledge of the characteristics of chemical components transported in the xylem
sap of trunks remains deficient and limited because no appropriate method exists to extract …

Bare-rooted seedlings are normally root-pruned prior to transplanting to facilitate the
planting process. This study was designed to determine the effect of root-pruning on …

Excessive N deposition leads to the conversion of previously N limited to N saturated forest
ecosystems. The input of N can result in severe N/P imbalance and N-induced P deficiency …

Trunk xylem sap nitrogen (N) composition can provide key information for interpreting tree N
transport strategies in a changing environment. However, there remains poorly explored to …

Storage and remobilization are considered key processes for the effective use of nitrogen in
temperate fruit trees. As dormancy begins, storage proteins are synthesized, coinciding with …
