Thirty fruit per replicate box were equilibrated in air at 20 C overnight.
Fruit skin color was determined using a colorimeter(Model CR-2500d, Minolta, Tokyo, Japan) and the data were
recorded as CIE a*, b*, and L* values. Measurements were taken on opposite sides of each fruit, midway between the pedicel and calyx.L* represents fruit skin lightness.
Fruit firmness (FF) was measured using a FirmTech 2 Fruit Firmness instrument (BioWorks Inc., Wamego, KS) by determining the force (N) requirement to compress the fruit for one millimeter.
