Banana seed

Banana(Musa acuminataor Musa balbisiana) is a giant herbaceous plant and is complete in its morphological characteristics, i.e., it has roots, an underground stem(rhizome), leaves, flowers, fruit, and seeds.

Any banana plant with fully-developed seeds that is found under natural conditions in the center of primary diversity is usually considered to belong to a wild Musa species.

Despite its having seeds, these are not usually viable, and therefore the multiplication of bananas commonly occurs by vegetative processes. Hard seed coat or physical dormancy is associated with a barrier to water imbibition in some seeds which subsequently leads to a reduced germination or complete germination failure.

However for wild Musa types are fully seeded and their fruits develop only after pollination. Fruit size depends on the number of seeds and a parenchymatous pulp develops around each seed.

Banana seed consists mainly of endosperm surrounded by multilayer outer integument (testa) and a thin inner integument (tegmen). The embryo is very small and is situated under the operculum or seed lid. The cells surrounding theembryo (for example, endosperm and testa) are reported to be responsible for blockage of water uptake during germination in some seeds.
