Occurrence of Alk(en)ylresorcinols in the Fruits of Two Mango (Mangifera indica L.) Cultivars during On-Tree Maturation and Postharvest Storage
Regarding
their relevance for the fungal resistance of mangoes
in long supply chains, the alkÂ(en)Âylresorcinols (AR) were quantitated
in peel and mesocarp throughout storage (27 days, 14 °C, ethylene
absorption). The 12 ‘Chok Anan’ and 11 ‘Nam Dokmai
#4’ lots picked between 83 and 115 days after full bloom (DAFB)
had different harvest maturity indices. The development of dry matter
and fruit growth indicated physiological maturity ∼100 DAFB.
During storage, all fruits ripened slowly, mostly until over-ripeness
and visible decay. The total AR contents always ranged at 73 ±
4.5 and 6.4 ± 0.7 mg hg<sup>–1</sup> of ‘Chok Anan’
and ‘Nam Dokmai #4’ peel dry weight, respectively, but
only at 6.7 ± 0.7 and 0.9 ± 0.1 mg hg<sup>–1</sup> for the corresponding mesocarp (<i>P</i> ≤ 0.05).
These narrow concentration ranges were contradictory to the decreasing
fungal resistance. Accordingly, the alkÂ(en)Âylresorcinols have not
been a deciding factor for the fungal resistance
