Question

explain how it is possible to grow on a commerial :

1. banana

2. virus free crop plants from virus infected good quanlity crop plants ?

Answer 1

Commercial propagation of banana occurs through corms and suckers. Tissue culture is used to propagate banana in a disease free manner.

Healthy crop plants (free from any infection such as viral) can be grown from infected crop plant through meristem culture. This is because meristem remains free from any infection. Meristem can be removed from shoot apex, root apex, or axillary areas of plant and then can be used to propagate virus free plants. Many of the crop plants such as banana, sugarcane, potato, etc have been successfully produced through meristem culture
