Browning was assessed visually by measuring total
browning areas of the pericarp on each of nine fruit.
The following scale was used: 1 = no browning (excellent
quality); 2 = slight browning; 3 = browning on less
than 25% of the total surface; 4 = 25–50% browning;
5≥50% browning (poor quality) (Jiang, 2000).
