<meta content="In the present study the linkage between hydraulic, photosynthetic
and phenological properties of tropical dry forest
trees were investigated. Seasonal patterns of stem-specific
conductivity (
K
SP
) described from 12 species, including
deciduous, brevi-deciduous and evergreen species, indicated
that only evergreen species were consistent in their
response to a dry-to-wet season transition. In contrast,
K
SP
in deciduous and brevi-deciduous species encompassed a
range of responses, from an insignificant increase in
K
SP
following rains in some species, to a nine-fold increase in
others. Amongst deciduous species, the minimum
K
SP
during
the dry season ranged from 6 to 56% of wet season
K
SP,
indicating in the latter case that a significant portion of the
xylem remained functional during the dry season. In all
species and all seasons, leaf-specific stem conductivity (
K
L
)
was strongly related to the photosynthetic capacity of the
supported foliage, although leaf photosynthesis became
saturated in species with high
K
L
. The strength of this correlation
was surprising given that much of the whole-plant
resistance appears to be in the leaves. Hydraulic capacity,
defined as the product of
K
L
and the soil–leaf water potential
difference, was strongly correlated with the photosynthetic
rate of foliage in the dry season, but only weakly
correlated in the wet season." name="eprints.abstract" />

and phenological properties of tropical dry forest&#13;
trees were investigated. Seasonal patterns of stem-specific&#13;
conductivity (&#13;
K&#13;
SP&#13;
) described from 12 species, including&#13;
deciduous, brevi-deciduous and evergreen species, indicated&#13;
that only evergreen species were consistent in their&#13;
response to a dry-to-wet season transition. In contrast,&#13;
K&#13;
SP&#13;
in deciduous and brevi-deciduous species encompassed a&#13;
range of responses, from an insignificant increase in&#13;
K&#13;
SP&#13;
following rains in some species, to a nine-fold increase in&#13;
others. Amongst deciduous species, the minimum&#13;
K&#13;
SP&#13;
during&#13;
the dry season ranged from 6 to 56% of wet season&#13;
K&#13;
SP,&#13;
indicating in the latter case that a significant portion of the&#13;
xylem remained functional during the dry season. In all&#13;
species and all seasons, leaf-specific stem conductivity (&#13;
K&#13;
L&#13;
)&#13;
was strongly related to the photosynthetic capacity of the&#13;
supported foliage, although leaf photosynthesis became&#13;
saturated in species with high&#13;
K&#13;
L&#13;
. The strength of this correlation&#13;
was surprising given that much of the whole-plant&#13;
resistance appears to be in the leaves. Hydraulic capacity,&#13;
defined as the product of&#13;
K&#13;
L&#13;
and the soil–leaf water potential&#13;
difference, was strongly correlated with the photosynthetic&#13;
rate of foliage in the dry season, but only weakly&#13;
correlated in the wet season.</p></div><table style="margin-bottom: 1em" cellpadding="3" class="not_ep_block" border="0"><tr><th valign="top" class="ep_row">Item Type:</th><td valign="top" class="ep_row">Article</td></tr><tr><th valign="top" class="ep_row">Additional Information:</th><td valign="top" class="ep_row">"The definitive version is available at www.blackwell-synergy.com"&#13;
