Abstract: | "Regarding their relevance for the fungal resistance of mangoes in long supply chains, the alk(en)ylresorcinols (AR) were quantitated in peel and mesocarp throughout storage (27 days, 14 degrees 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 approximately 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(-1) 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(-1) for the corresponding mesocarp (P = 0.05). These narrow concentration ranges were contradictory to the decreasing fungal resistance. Accordingly, the alk(en)ylresorcinols have not been a deciding factor for the fungal resistance" |
