Vegetative Propagation:-

  • There are many plants in which parts like the root, stem and leaves develop into new plants under appropriate conditions.
  • Buds produced in the notches along the leaf margin of Bryophyllum fall on the soil and develop into new plants
  • Different types of vegetative propagation in plants include stem cutting, grafting, layering.
  • Grafting involves fusion of tissues of one plant with those of other plants grafting is a vegetative method of propagating for apples and roses.

Advantages of vegetative propagation:-

-Plants raised by vegetative propagation can bear fruits and flowers earlier than those produced from seeds.

-All plants produced are genetically similar enough to the parent plant to have all its characteristics.

TISSUE CULTURE:-

  • In tissue culture, new plants are grown by removing tissue or separating cells from the growing tip of a plant. The cells are then placed in an artificial medium where they divide rapidly to form a small group of cells or callus.
  • The callus is transferred to another medium containing hormones for growth and differentiation.
  • The plantlets are then placed in the soil so that they can grow into mature plants.
  • Using tissue culture, many plants can be grown from one parent in disease-free conditions.
  • This technique is commonly used for ornamental plants.
