Convergent nitrogen–phosphorus scaling relationships in different plant organs along an elevational gradient.

ABSTRACT: We found the scaling exponents of the N-P relationship were not significantly different from 1.0 in all organs, with a common slope of 1.08. The numerical values of the scaling slopes and the scaling constants did not differ regardless of elevation. These results indicated the different organs of subtropical woody plants share a similar isometric scaling relationship between their N and P content. Moreover, the effects of the N and P content on the N:P ratio differ between metabolic organs (leaves and fine roots) and structural organs (twigs), elucidating the stoichiometric regulatory mechanism of different organs.
