Explain the following methods of propagation and name the crop associated with each : (i) bud grafting (ii) ratoon cropping -Geography
by

1 Answer

Answer :

(i) Bud grafting—It is associated with rubber crop. This method is done by the insertion of a strip of bark containing a bud from high yielding clones under a bark of a young seedling about 5 cm high till they become united in 3 to 4 weeks. The old seedling stem is then sawn off above the grafted bud, which then grows to form a new rubber plant.  (ii) Ratoon cropping—It is associated with sugarcane. It is a process by which the cane is cut close to the ground where the sugar content is concentrated. After the crop has been cut the stem begins to grow again and produces a second crop called ratoon.
