Abstract

The effects of fertilization on leaf longevity and leaf mortality in the Alaskan evergreen shrub, Ledum palustre (Ait.) Hult., were investigated in a field experiment. The results are consistent with previous research suggesting that one function of overwintering evergreen leaves is to serve as nutrient storage organs, a function that is superfluous when nutrient supplies for new growth can be obtained from current uptake.
