    Durian Harvesting

    Uploaded by

    Kusuma Darma
    Durian is a controversial fruit native to Southeast Asia that is harvested manually from trees. The technology describes harvesting durian that has reached maturity, identified by characteristics like a visible abscission layer and hollow sound when tapped. Mature fruits are cut above the abscission layer and placed in baskets to transport to sorting without touching the ground. Proper harvesting allows durian to have a longer shelf life than fallen fruit and supports new orchards with varieties having thin pericarps vulnerable to damage from dropping.
