Seasonal differences in nitrogen storage in deciduous and evergreen species of a tropical dry forest

Abstract

Reserves of twig nitrogen of drought-deciduous species changed seasonally and provided some of the nitrogen required for canopy reconstruction after drought relief. By contrast, in evergreen species, nitrogen mobilization from old leaves and use in expanding leaves occurred simultaneously at the time of leaf exchange and twig nitrogen remained constant © 1995 Institute of Experimental Botany, ASCR.
