The postharvest treatment with benzothiadiazole, chitosan, fir
extract, the algal oligosaccharide laminarin, and potassium bicarbonate
at different concentrations decreased the total rot of the
‘Burlat’ cherries cold-stored for 14 d (0.5
±
1 ◦C) and then exposed
to 7 d of shelf-life (20
±
1 ◦C, 95–98% RH; Table 3). The most effective
treatments in controlling postharvest total rots of sweet cherry
were chitosan and potassium bicarbonate at concentrations ranging
from 4 to 26 g/L. For brown rot, gray mold and total rot,
chitosan reduced the infection indices by 67%, 88% and 75%, respectively,
and 26 g/L potassium bicarbonate by 75%, 92% and 76%,respectively.
