Mango wilt, caused by Ceratocystis fimbriata,
is a disease of great economic importance in mango
production. Considering that the physiological effects
of this vascular disease are not fully characterized,
this study aimed to investigate some alterations in
mango leaves from cultivars Ubá and Tommy
Atkins, respectively, resistant and moderately resistant
to mango wilt. The relationships between relative
lesion indices (upward relative lesion length
(URLL), the downward relative lesion length (DRLL)
and the radial fungal colonization (RFC)) and water
relations and gas exchange and chlorophyll a fluorescence
parameters were evaluated at 10, 20 and 30 days
after inoculation. The foliar concentrations of lipid peroxidation,
total pigments and total free amino acids and
proline were also determined. The URLL, DRLL and
RFC increased overtime in both Ubá and Tommy
Atkins cultivars, but reached the greatest values for cv.
Tommy Atkins. Although cultivars did not present
contrasting results for most of the evaluated parameters,
the relative changes between inoculated
and non-inoculated plants of each cultivar were more
disparate in plants from cv. Tommy Atkins. There were
decreases of 55, 73, 65 and 22 %, respectively, for net
carbon assimilation rate (A), stomatal conductance to
water vapor (gs), transpiration rate (E) and internal-toambient
CO2 concentration ratio (Ci/Ca) for inoculated
plants from cv. Tommy Atkins in comparison to the
non-inoculated plants. For inoculated plants from cv.
Ubá, there were decreases of 25, 41 and 36 % for A, gs
and E while Ci/Ca decreased by 17 % in relation to the
non-inoculated plants. Inoculated plants of cvs. Tommy
Atkins and Ubá showed pronounced reductions for
midday leaf water potential and apparent hydraulic conductance
relative to the control. Inoculated plants from
cv. Ubá showed values of predawn leaf water potential
that were 25 % higher in comparison to inoculated
plants from cv. Tommy Atkins. In addition, decreases
in total chlorophyll concentration as well as increases in
free amino acids and lipid peroxidation occurred for
inoculated plants from cv. Tommy Atkins. MenosMango wilt, caused by Ceratocystis fimbriata,
