The effect of enhanced nitrogen on aboveground biomass allocation and nutrient resorption in the fern Athyrium distentifolium

Original language description

We measured aboveground biomass allocation and resorption of nitrogen (N) and phosphorus (P) in the fronds of a winter-deciduous fern Athyrium distentifolium in ambient and N-enhanced treatments. A.distentifolium formed taller fronds and petioles and allocated more biomass to supporting tissue relative to photosynthetically active leaf tissue in response to N addition. Resorption of P from green fronds was more efficient than N resorption (on average 50% P, 21% N from supporting and 44% P, 24% N from photosynthetic tissues were withdrawn during senescence). The N/P-ratios were higher in photosynthetic tissue in comparison with supporting tissue. In N-enhanced treatment, a positive relationship was found between the amount of supporting tissue relativeto photosynthetic tissue and resorption of nutrients from photosynthetic tissue. However, higher N availability resulted in a significant decrease of N resorption efficiency in photosynthetic tissue of A. distentifolium.
