Soil nitrogen drives inverse acclimation of xylem growth cessation to rising temperature in Northern Hemisphere conifers

[Significance] Theory and experiments suggest that rising soil nitrogen (N) could delay the cessation of the growing season based on leaf phenology data, but no intercontinental analyses on xylem phenology have been carried out. Using data on xylem phenology from conifers across the Northern Hemisph...

Descripción
Sumario:[Significance] Theory and experiments suggest that rising soil nitrogen (N) could delay the cessation of the growing season based on leaf phenology data, but no intercontinental analyses on xylem phenology have been carried out. Using data on xylem phenology from conifers across the Northern Hemisphere, we found that rising soil N delays the end of xylem cell wall thickening but advances the cessation of cell enlargement. While xylem cell enlargement is responsible for stem size growth, cell wall thickening accounts for 90% of woody biomass production. The contrasting effects of soil N on these two xylem differentiation processes would affect xylem cell anatomy and consequently influence water transport and wood density in conifers.
