Asexual Plant Propagation

1. ASEXUAL PLANT
PROPAGATION

2. Learning Objectives
At the end of the period, you should
be able to:
identify the various asexual plant propagation methods;
enumerate and explain the advantages and disadvantages of
asexual plant propagation;
understand the underlying principles of the various types of
asexual plant propagation; and
identify plants in the immediate surrounding that can be
propagated asexually.

3. asexual plant
propagation
a method using a growing part
of a plant (other than its seeds)
to produce a new plant
also known as "vegetative
reproduction" or "clonal
propagation"- does not involve
the seed cycle

5. Cutting
involves taking and manipulating
a portion of the stem from a
parent plant to establish a new
plant
new plant is referred as a "clone"
STEM

6. Galate, 2020

7. Cutting
done through removal of a piece
of plant blade and planting it on
soil or water

9. Cutting
roots are cut into 2-6-inch
segments and then planted to
allow the development of shoots
from the root

11. Layering
involves the rooting of aerial
stems or branches while still
attached to the parent plant
allow the plant to develop
adventitious roots

12. LAYERING
Air layering Trench layering Mound layering

13. Air Layering
stem is wounded by removing the bark
(3-5 cm), packing/wrapping it with
soil/coco peat, and covering it with plastic
to hold the soil/coco peat
roots are allowed to grow from the wound
of the stem
rooted branch may be severed from the
mother plant

biological-sciences/air-layering

14. Trench Layering
stem of the plant is placed horizontally on
the ground covered with soil to allow
development of roots
after roots developed, the stem is
detached from the mother plant

15. Mound Layering
involves growing the plant first and when
it is mature, it is cut at the soil level
once the shoots have emerged, mound soil
allowing shoots to grow faster and
develop roots

16. Separation and
division
usually used for specialized roots or stems
of plants
involve removal by cutting or pulling the
planting materials

17. Separation and
division
cutting/pulling the planting materials
from a clump of specialized stems such as
bulbs, bulbils, corms, rhizomes, stolons,
tubers or suckers
(Synge and Herklots, 2019)

19. Grafting
a shoot or bud stick consisting of
several buds is taken from a healthy
tree of the desired variety is
inserted into the limb or trunk of a
seedling
Rootstock
- serves as the root system
Scion
- serves as the shoot

20. The basic principle of grafting is on matching the scion
and stock (meristematic tissue, whose cells are
undifferentiated and capable of regular division of cell
division).
In the process of healing, the plant will create a union
wherein the rootstock will provide water and nutrient to
the scion while the scion provides the products of
photosynthesis to the roots (Sharma and Manish, 2004).

21. How To Select a
Rootstock?
Identify the characteristics of the plant.
Make sure that it has good root
characteristics.
Make sure that it is not susceptible to
diseases and pests

22. Why Graft?
To maintain the good characteristics of the
mother plant.
For the plant to bear fruits earlier than
those propagated by seeds.
To grow the variety that is not adapted to
the soil condition that we have.
To produce plants which do not produce
seeds and remain dormant in a longer
period of time.

23. How To Select a Scion?
Determining its desirable traits or
characteristics.
It should be free from diseases and pests.
It should have buds which are not
dormant.

24. Budding
uses a single bud that is attached to or
inserted into a stock
to produce a greater number of new plants
from a single bud stick
