Delayed autumnal leaf senescence following nutrient fertilization results in altered nitrogen resorption.

Increased atmospheric nitrogen(N)deposition could create an imbalance between N and phosphorus(P),which may substantially impact ecosystem functioning.Changes in autumnal phenology(i.e.,leaf senescence)and associated leaf nutrient resorption,which is an important nutrient conservation mechanism in plants,may profoundly impact plant fitness and productivity.However,we know surprisingly little about how and to what extent nutrient addition affects autumnal lea…查看全部>>
