Resorption proficiency and efficiency of leaf nutrients in woody plants in eastern China

Aims (i) t o explore variations in nutrient resorption of woody plants and their relationship with nutrient limitation and ( ii) to identify the fac- tors that control these variations in forests of eastern china. Methods We measured nitrogen (N) and phosphorus (P) concentrations in both green and senesced leaves of 172 woody species at 10 for - est sites across eastern china. We compared the nutrient resorption proficiency (Nu r P) and efficiency (Nu r E) of N and P in plant leaves for different functional groups ; we further investigated the latitudi - nal and altitudinal variations in Nu r P and Nu r E and the impacts of climate, soil and plant types on leaf nutrient resorptions.
