abstract = {Yellow cypress (Chamaecyparis obtusa (Siebold $\&$ Zucc.)
Endl. var. formosana (Hayata) Rehder) is the predominant
tree species of Taiwan's nutrient-poor, mountain fog
forests. Little is known about the potential contribution of
solute uptake from fog to the overall nutrition of these
trees. Shoots of yellow cypress seedlings were misted with
artificial fog containing the tracer rubidium (Rb) in
laboratory and field experiments to determine if there is
solute uptake from the fog. After misting shoots for six
weeks, substantial amounts of tracer were detected in
unexposed roots by inductively coupled plasma mass
spectroscopy bulk analysis.Possible routes of entry were
examined by element imaging with energy dispersive X-ray
analysis. Direct uptake of the tracer into leaves across the
cuticle and epidermis was small, excluding this as the major
uptake path. Accumulations of Rb were found on leaf surfaces
along the edges of the leaves. The almost daily changes in
fog coverage and air humidity may enhance the accumulation
of fog solutes at leaf edges. Accumulation of Rb was also
found in narrow clefts between opposite leaves and between
the outermost and underlying alternating stacked leaves. The
clefts provide a direct passage from the leaf surface to the
space beneath the imbricate leaves and the underlying
alternate leaves, possibly facilitating solute uptake from
fog, which in turn may contribute to the nutrition of yellow
cypress.},
