Superior quality plantlets are produced by joining the stems of two plants of the same species.”



WHAT IS GRAFTING ?

  • Grafting is another method used to produce superior quality plantlets.

  • Superior quality plantlets are produced by joining the stems of two plants of the same species.



WHAT ARE STOCK & SCION ?

The rooted plant selected for grafting is called stock

The branch selected for grafting is

called scion.

EXAMPLE

Branches of mango trees like neelam, malgova etc. can be grafted to the plantlets of indigenous mango trees. Here, the plantlet of the Indigenous mango tree is the Stock and the branch of Malgovais the Scion .


WHAT ARE THE PROCEDURE OF GRAFTING ?


STEP 1

Peel off the bark from the facing sides of both the stock and scion in 3 ½cm length.

STEP 2

Bring the peeled off portions of stock and scion in contact with each other. Wrap them together firmly with a jute twine.

STEP 3

Cover it with a wax cloth or a plastic tape. After one month, cut partially the stock above the covered area and the scion below.


STEP 4

Wait for one more month and cut and detach the part completely. When it attains proper growth, it can be replanted in a more suitable place. Remove any new branches sprouting on the stock.


WHAT IS BUDDING ?

  • In this method, a bud is grafted, instead of grafting a branch to another plant.

  • This method can be used to produce flowers of different colours in the same plant.

  • Buds of other varieties can be grown on indigenous varieties.


WHAT ARE THE PROCEDURE OF BUDDING ?


STEP 1

Cut off the bud from a quality plant.

STEP 2

Make a ‘T’ shaped cut on the plant on which the bud is to be grafted and leave the bark open.

STEP 3

  • Insert the bud into the 'T' shaped cut on the bark.

  • Wrap it in such a way that the bud is exposed.

STEP 4

Cut off the upper part of the stock when the bud attains proper growth.



WHAT IS HYBRIDISATION ?

Hybridisation is the method of producing new seeds through artificial pollination between plants of the same species but of different characteristics.

Seeds formed in this manner may combine advantages, disadvantages and mixed qualities of both the parent plants. Seeds with desired qualities are selected from these.
