Transcript of Asexual Propagation

Layering
development of
roots
on a
stem
while it is still attached to the parent plant
the rooted stem is then detached to become a new plant growing on its own roots.
Slowest method
Asexual Propagation
Ms. Metcalf

Why do we use asexual propagation in plants?
cost effective
clone of parent plant
disease free stock
plants are produced quicker
no seeds
Popular types of asexual propagation in plants
cuttings
layering
grafting
separation
division
budding
tissue culture
Cutting procedure
Cut off plant part with clean knife or scissors
Dip in
rooting hormone
Plant in moist potting material
What is
asexual
propagation?
The production of
offspring
by use of
vegetative
parts, rather than a
seed
of a plant used to produce a new plant.

Cuttings
most common and simple method
can be taken from
stem, leaves, and roots
Optimal environment for rooting


Dolly
involves placing a section of a stem (
scion
) of one plant into another plant.
the part of the plant that grows from the scion will have traits of its
parent.

air layering
simple layering
Many plants are patented- illegal to propagate asexually.
Optimal rooting environment
proper temperature
high humidity
sufficient light

intermittent mist system
Separation
Show what you know!
In a group, create & market your own business that utilizes asexual propagation practices.
1. What do you know about asexual propagation?
2. How do you think asexual and sexual propagation differs?
3. What don't you know yet about asexual propagation?
Disadvantages
no variety in offspring
less chance of survival in varying environment

Compare and contrast the asexual propagation techniques.
Discuss the advantages and disadvantages of asexual propagation.
Create a real-life scenario where one would use asexual propagation.
