Mango wilt, caused by Ceratocystis fimbriata, is one
of the most important diseases affecting mango yields in Brazil.
Information regarding the biochemical mechanisms involved in mango
resistance against C. fimbriata is absent in the literature. Thus, the
present study determined and quantified alkaloids and phenolics in
the stem tissue of mango plants from Palmer (susceptible) and Ubá
(resistant) cultivars. Furthermore, it was examined the effect of these
secondary metabolites against C. fimbriata growth in vitro. The highperformance
liquid chromatography revealed that the concentration
of two alkaloids (theobromine and 7-methylxanthine) and six phenolic
compounds (caffeic acid, p-coumaric acid, gallic acid, protocatechuic
acid, catechin and epicatechin) in the inoculated plants from cv. Ubá
was higher in comparison with inoculated plants from cv. Palmer.
The concentration of the secondary metabolites was higher in the
non-inoculated plants from cv. Palmer than in the inoculated ones,
while the opposite was observed for plants of cv. Ubá. Peaks in the
concentrations of secondary metabolites in the inoculated plants
from both cultivars occurred at 7 and 14 days after inoculation. The
different concentrations (10 to 30 mg∙mL−1) of secondary metabolites
added to the Petri dishes greatly inhibited C. fimbriata growth over
time. These results suggest that secondary metabolites played an
important role in the resistance of mango plants against C. fimbriata
infection. |
