* Give 2 examples of Natural Vegetative Reproduction
* Give 1 reason why Natural Vegetative Reproduction
is important
Day 1
+ Vegetative Regeneration
Asexual
reproduction
 Can
be Natural or Artificial using parts of
the plant for reproduction aside from the
flowers
 Natural-occurs in nature and plants do
this on their own
 Artificial-man made way of reproducing
plants using plant parts
 Flowering plants also reproduce sexually
 Two parent plants are needed

ADVANTAGES
 Help
conserve or
increase the
population of rare or
endangered plants
 Better
crops in a
shorter time period
 Requires
attention
less care and
DISADVANTAGES
 Risk
of total
destruction of an entire
crop of plants as the
plants produced are
prone to the same
disease
 Competition
for
nutrients and
overcrowding due to
fat growth

Reproduction
+ Natural Vegetative Regeneration
UNDERGROUND STEMS
 Stems
which grow
underground
 Potato, ginger, onion
+ Natural Vegetative Regeneration
SUCKERS
 Part
of the stem that
shoots upright
 Banana, pineapple
and heliconia (birds
of paradise)
+ Natural Vegetative Regeneration
Leaves

Usually those which are
thick and fleshy

Small leaves form
alongside the leaves.

The small leaves develop
roots

These small leaves and
roots fall off to the ground
and may develop into new
plants.

Begonia and bryophyllum

CUTTING
 Plant
part is cut,
transplanted to the
soil so it can grow into
a new plant
 STEMS
 Used in most garden
plants with woody stems
 Conditions: leaves are
removed, soil must be
moist and sun is kept away
 Hibiscus, chrysanthemum,
basil, rosemary, geranium
+ Artificial Vegetative Regeneration
CUTTING
 Plant
part is cut,
transplanted to the
soil so it can grow into
a new plant
 ROOTS
 Plants with woody stems
 Conditions: roots is
transplanted just below
the soil
 Roses, jade plant, japanese
angelica tree, blue passion
flower
+ Artificial Vegetative Regeneration
CUTTING
 Plant
part is cut,
transplanted to the soil
so it can grow into a
new plant
 LEAVES



One new plant from leaf
base; others can be multiple
plants in a leaf base
Conditions: base of the leaf
is planted in moist soil then
leaves will start growing
from the base
African violet, sansevieria,
snake plant, peperomia
+ Artificial Vegetative Regeneration
GRAFTING

Growing one part of a plant
in another part of a plant

A stem with a leaf bud is cut
from a parent tree (GRAFT)

Another plant is selected for
its root system (STOCK)

Graft is inserted to the stock
and bounded but kept moist
and away from the sun

Method used for fruit trees
such as apples, avocado and
guava
+ Artificial Vegetative Regeneration
BUDDING
 Bud
is inserted to a
stock plant
 The
bud is tied and
when bud grows into
a shoot, the part
above the shoot is cut
 Fruit
trees and leafy
trees such as peach
and orange trees
+ Artificial Vegetative Regeneration
AIR LAYERING

Bark of branch is stripped;
this wound is covered with
soil

The wound develops roots
and is transplanted to soil.

This will eventually develop
into a new plant

Method used for plants that
take a long time to develop
roots such as fruit, woody or
indoor plants

Lychee and pomegranate

What is the
significance of the
knowledge of
vegetative
regeneration to
our country and to us
as individuals?
