VEGETATIVE REPRODUCTION

Vegetative reproduction is an asexual mode of reproduction where the new individual rises from the vegetative parts of the plant, like stem, roots and leaves. For example:

1.       Stem: onion, ginger, potato etc.

2.        Roots: sweet potato, dahlia, guava etc.

3.       Leaves: bryophyllum

Due to the presence of adventitious cells on the vegetative parts of the plants they are able to give rise to new individual.

TYPES OF VEGETATIVE REPRODUCTION

1.      Budding:  

In bryophyllum, the adventitious cells are present in the notches of the leaf margins where new individual rises and separates itself for the parent and drops into the soil. This is also practiced in agriculture. This is called budding.  (You can relate it to the budding in yeast that we studied earlier right? Like the separation part then how the individual is identical to the parent.)

2.      Layering: 

In jasmine, the stem is taken and buried around 6-9 inches under the ground. The stem grows roots and a new individual rises. (Imagine a whole jasmine garden can be created with this with just one jasmine flower wow!). This is called layering.

3.     Grafting: 

In plants like roses, mangoes and oranges their reproductive capacity is less. So they are made to reproduce through grafting. In grafting the stem of a plant is cut and is replaced by stem of another plant of same species.  

ADVANTAGES OF VEGETATIVE REPRODUCTION

1.      1.  The plants produced by vegetative reproduction grow faster meaning they bear fruits and flowers faster as compared to the one grown from traditional seed method.

2.     2.   The offspring will be identical to the parent. (identical means perfectly similar just like doppelganger )  

3.       3. The plants that have less reproductive capacity (like rose, mangoes, oranges) can be grown through this method.
