The shell color of pineapple fruit changes from green to yellow during maturation.Fruit began to change color at 120 days after full bloom but the pattern of change of shell color depends on growing season.In early crop, at harvesting date of 120 days after full bloom, when the fruit is ready, for consumption,85% of fruits are still green .In contrast,40% of fruit in the late crop had been changed to color score 3 (two lower row of eyes became yellow).At the optimum harvesting date 130 days after full bloom more than 75% of the early crop was ripened with green shells (color score 1 and 2) whilst 85% of late crop fruits were yellow (color score 3-4 )
