ASEXUAL PROPAGATION

(Grafting, Marcotting, Budding)

ASEXUAL PROPAGATION

• It is done without the help of the sex organs of the plants

• An artificial method which new plants are produced and multiply by using parts and buds of selected mother plants.

Artificial plant propagation isdone by:

A. Cutting• New plants are produced andmultiplied by

cutting and planting parts of the plants.B. Layering• A part or branch of the tree is introduced

into the soil to develop roots while being fed by the parent plant.

C. Marcotting• The stems are induced to take roots while

still attached to the mother plant.

D. Grafting• An artificial plant propagation through which

stem of 1plant, called ´the scion´ (top portion), is inserted into the root stock of another plant.

E.Budding• It uses a single band asthe scion instead of the

stem bearing several buds.It is generally used on smaller branches of large plant where the buds can be inserted into shoots1-3 dm.

F. Inarching• In this method, the scion is made to unite with

the root stock while growing on their own root system

Steps in Marcotting:

1. Remove a ring of the bark below the node 3-5 cml ong.

2.Scape the cambium layer but not too deep into the wood to prevent healing before root formation takes place.

3. After callus formation has taken place, wrap the cut surface with a moist, but not wet sphagnum moss. If sphagnum moss not available, used moistened soil and wrap with coconut husk.

4. Cover securely with plastic and tie around on both ends with the cotton wine to prevent drying of the rooting medium.

5. When enough roots grow,cut off the marcot just below the ball of sphagnum moss or soil that holds the root.

6.After cutting the marcot,place in a pot big enough to provide sufficient room for the roots to develop further before the transplanting tothe field.

7. Place in a cool and shady plants to hasten recovery.

HOW TO MARCOT A PLANT?

MATERIALS NEEDED:

• 1 4X8 inces cellopane

• 2 adhesive tape

• scissor

• sharp knife cutter

• compost soil

• Step 1: Select a plant. • Step 2: Select a

matured branch. Remove around 2 inches of the skin. See image below

PROCEDURES:

• Step 3: Cut the base of the cellophane making it open from top to bottom.

• Step 4: Slowly insert the cellophane to the targeted branch. Settle it just below the peeled portion of the branch.

• Step 5: Seal the base of the branch with adhesive tape.

• Step 6: Pour in the compost soil. Make sure you added a little bit of water to it and also, make sure that the peeled portion are covered with soil.

• Step 7: Wrap around the top portion of the cellophane and seal it with tape.

STEPS/PROCEDURE in BUDDING

Steps in Budding

• Root stock cutting

1. Pick well-developed buds from a terminal growth of a desired variety.

2. Clip off the leaves immediately to stop evaporation.

3. Select a smooth area and cut a T-shaped slit through the bark.

4. Insert a bud and cut a bud from a bud stalk with the shield-shape piece of bark and a very thin layer of wood under the slit. Slip the bud on the stock and shove it into position.

5.Tie the bud securely above and below with a soft cord and a plastic sheet of raffia.

6. If union has taken place after two weeks, cut the raffia on the side away from the bud to prevent girdling. A living bud is greenish in color, while a dead one is blackish.

7. Cut the stock smoothly when it reaches the heightof 30cm. Cover the surface with pine tar or house paint to prevent decay.

Sample of Grafting

Steps in Cleft Grafting

1. Select a clean, smooth limb between 2-3 cm indiameter and saw it off2. With a sharp narrow blade, split the stub

through the middle, taking care to make a clean slit

3. Cut two scion with tree buds each and about 10-15cm the lower end of each scion. Sharpen

to form long, evenly tapering wedge.4. Open the cleft in the stubby forcing a chisel or

any similar instruments into this center.

5. Insert a wedged-shaped end of a scion so that its innermost bark lies against the innermost bark of thesplit stub.

6. Cover all cut surfaces immediately with soil. Letboth scions grow from1-2 years.
