abstract = {Emission from plants is a major source of atmospheric
methanol. Growing tissues contribute most to plant-generated
methanol in the atmosphere, but there is still controversy
over biological and physico-chemical controls of methanol
emission. Methanol as a water-soluble compound is thought to
be strongly controlled by gas-phase diffusion (stomatal
conductance), but growth rate can follow a different diurnal
rhythm from that of stomatal conductance, and the extent to
which the emission control is shared between diffusion and
growth is unclear. Growth and methanol emissions from
Gossypium hirsutum, Populus deltoides, and Fagus sylvatica
were measured simultaneously. Methanol emission from growing
leaves was several-fold higher than that from adult leaves.
A pronounced diurnal rhythm of methanol emission was
observed; however, this diurnal rhythm was not predominantly
determined by the diurnal rhythm of leaf growth. Large
methanol emission peaks in the morning when the stomata
opened were observed in all species and were explained by
release of methanol that had accumulated in the
intercellular air space and leaf liquid pool at night in
leaves with closed stomata. Cumulative daily methanol
emissions were strongly correlated with the total daily leaf
growth, but the diurnal rhythm of methanol emission was
modified by growth rate and stomatal conductance in a
complex manner. While in G. hirsutum and in F. sylvatica
maxima in methanol emission and growth coincided, maximum
growth rates of P. deltoides were observed at night, while
maximum methanol emissions occurred in the morning. This
interspecific variation was explained by differences in the
share of emission control by growth processes, by stomatal
conductance, and methanol solubilization in tissue water.},
