Concept: vegetative reproduction is a part of the vegetative organs of higher plants-roots, stems and leaves, which develop into a new individual after falling off from the mother.

Advantages: 1: asexual propagation can maintain the excellent characters of parents, so flowers, fruit trees, tea, sugarcane, bamboo and other artificially cultivated plants all adopt this propagation method.

2. Large-scale cultivation of a single trait for genetic research.

3. Give some rare plants with reproductive disorders the hope of reproduction.
