Nitrogen (N) withdrawn from leaves before abscission can help to supply N requirements in plants of nutrient poor habitats. Besides N shortage, Mediterranean Quercus seedlings must face water and light stresses. However, there is little information on the influence of these stresses in the nitrogen resorption efficiency (NRE) at leaf level, and none at canopy level. We tested in two separated experiments how changes in water and light availability affect NRE and its components at both levels in… CONTINUE READING
