Abstract

The effects of simulated soil fertility at three levels (poor, medium, and rich soils) and moisture stress at two levels (well watered versus moisture stressed) on gas exchange and foliar nutrient resorption in 1+0 bareroot northern red oak (Quercus rubra) seedlings were evaluated. Current nitrogen (N) uptake was labeled with the stable isotope ¹⁵N to enable discrimination and quantification of the different N pools in new growth of plants, and the proportion remobilized and/or resorbed following senescence.
