Asexual Reproduction in Plants

Updated on July 3, 2015

Continuous Process of Species

The ability of an organism to produce a new generation of individuals of the same species is called Reproduction.
Different methods of reproduction can be broadly grouped into two types.
1. Asexual reproduction.
2. Sexual reproduction.
First let us learn about the asexual reproduction in plants.

Asexual Reproduction in Plants
Asexual Reproduction occurs in different ways in different organisms like yeasts, fungi, algae, mosses, ferns and flowering plants.
It Occurs
1. Through Sporangia e.g.: Mucor
2. By budding e.g.: yeast

3. By fragmentation e.g.: Fungi
4. By Fission e.g.: Euglena

Vegetative Reproduction

  • Vegetative propogation occurs in many plants in a natural way. There is no fusion of gamets like sexual reproduction.
  • New plants are formed from vegetative parts of the plants like stem, root, leaf etc.
  • Buds which are formed in different parts of the plant provide a source of vegetative propogation.

Different Methods of Vegetative Propogation
1. Suckers e.g.: Chrysanthemum.
2. Nodes e.g.: Grass
3. Eyes of Potato e.g.: Potato
4. Leaf buds e.g.: Bryophyllum
5. Root buds e.g.: Curry leaf, Neem

Advantages of Vegetative Propagation

  • It helps to maintain fixed qualities and characteristic features of the parent plant.
  • In ornamental plants with attractive flowers and leaves can be continued in next generation.
  • Such plants can be produced in large numbers in a short time.
  • This method is useful to develop new varieties with useful characters.
  • It is very useful of reproduction that rarely produce flowers.

Artificial Methods of Vegetative Propagation
This most popular methods are
1. Cutting
2. Grafting

Cutting: In this method, a portion of any Vegetative part like root or stem is separated from parent plant and placed it in a suitable soil and environmental conditions.
The cutting from root and shoots develop into new plants.
Mainly there are two types in this method.
1. Stem Cuttings e.g.: Hibiscus 2. Root Cuttings e.g.: Carrot

Layering: It is an alternative where propagation through cuttings is difficult.
There are two types in this process.
1. Air Layering
2. Ground Layering

Grafting: It provides an opportunity to bring the characters of different plant into
one plant. There are four types of Grafting.
1. Approach Grafting
2. Cleft Grafting
3. Tongue Grafting
4. Bud Grafting.

Advantages of Grafting:

  • It helps to preserve and perpetuate varieties that cannot reproduce by vegetative propagation.
  • A high yielding commercial tree can be grafted to a hardy root stock, that is more resistant to disease, pests and droughts.

Plant tissue culture
In 1902, G Haberlandt noticed that the plant cells are grown in synthetic media.
In this method, a cell or a tissue is taken from a plant and cultured in suitable containers in which nutrient medium is present.
By this method, thousands of plants can be produced from a single desirable parent in one generation.
