Caused by the vascular fungus Ceratocystis fimbriata, mango wilt is considered to
be one of the most serious threats in mango-producing regions worldwide. However, changes
in leaf gas exchange level and the mechanisms underlying host responses to this fungal infection
remain poorly described. This study aimed to evaluate potential changes in the leaf gas
exchange of different mango cultivars (Ubá, Espada, Haden and Tommy Atkins) in response to
two Brazilian isolates of C. fimbriata (CEBS15 and MSAK16) to non-invasively assess cultivar
variability in relation to the basal level of resistance to mango wilt. Both isolates, regardless
of the cultivar, caused reductions in stomatal conductance and, thus, a reduction in CO2 assimilation
via diffusive limitations. Taking into account the full length of the internal lesion and
the radial colonization of the stem tissues, both isolates showed equivalent aggressiveness
when inoculated into the Haden and Tommy Atkins cultivars. Conversely, when compared to the
CEBS15 isolate of C. fimbriata, the MSAK16 isolate was more aggressive in cv. Espada and less
aggressive in cv. Ubá. |
