Relationship between the relative limitation and resorption efficiency of nitrogen vs phosphorus in woody plants.

The inverse relationship also existed for plants with different leaf habits ( r 2 = 0.14, 0.25, and 0.30, and p < 0.0001, 0.0001, and 0.05 for DB, EB and conifer, respectively; Figure 1b-d ), although it was only marginally significant for N-fixers ( r 2 = 0.20; p = 0.053; Figure 1d ).
