  • question_answer 132) New Banana plants develop from

    A)  Rhizome                    

    B)  Sucker

    C)  Stolen                        

    D)  Seed

    Correct Answer: A

    Solution :

    Each pseudostem produces a single bunch of banana, before dying and is replaced by a new pseudostem. The base of the plant is a rhizome (known as a corm). Corms are perennial, with a productive lifespan of 15 years or more. Cultivated bananas are parthenocarpic, which makes them sterile and unable to produce viable seeds. In lacking seeds, another form of propagation is required. This involves removing and transplanting the parts of the underground stem (known as corm). Usually this is done by carefully removing a sucker with some roots intact. However, small sympodial corms, representing not yet elongated suckers are harder to transplant and can be left out of the ground for up to 2 weeks; they require minimal care and can be boxed together for shipment.
