Assessing the Rate and Timing of Leaf Wax Regeneration in Fraxinus Americana Using Stable Hydrogen Isotope Labeling
RATIONALE
Understanding leaf wax regeneration and recycling is crucial for plant physiology and paleoclimate studies. However, our recent isotope labeling experiments on a grass species (Phleum pratense) yielded different conclusions from published data on a tree species (Populus trichocarpa), with the former showing rapid regeneration and the latter little regeneration in mature leaves.
