Sorosis: The fruit is produced from the entire spike, catkin or spadix inflorescence in which the flowers fuse by their succulent perianth (tepals). The inflorescence axis becomes fleshy or woody and forms a compact mass e.g., Jack fruit (Artocarpus heterophyllus), Pineapple (Ananas comosus), Mulberry (Morns indica). In Pine apple the perianth as well as the axis bearing flowers and the bracts become fleshy and succulent and form the edible part of it. In Mulberry – edible part is fleshy perianth.
