Which of the following is a method of plant propagation that involves the use of plant parts?
Seed propagation
Tissue culture
Layering
Grafting
Correct answer is D
Grafting is a method of plant propagation that involves the use of plant parts. It is a horticultural technique whereby tissues of plants are joined so as to continue their growth together. The upper part of the combined plant is called the scion while the lower part is called the rootstock. The success of this joining requires that the vascular tissues grow together and such joining is called inosculation.
