Jackfruits can reach very large size (as much as 90 cm long, 50 cm wide, and 25 kg in weight), depending on the cultivar, production area, and the fruit load on the tree. Color change from green to yellow to brown is used as an indication of maturity and ripeness stages. Optimum harvest for long-distance transport is when the fruit changes color from green to yellowish-green. Fruits are harvested with a portion of the stalk attached to be used in handling them.
