Answer p. 18-19 of the activity book (Act. 5.1)
Day 1
+Vegetative Regeneration
Asexual reproductionCan be Natural or Artificial using parts
of the plant for reproduction aside from the flowersNatural-occurs in nature and plants
do this on their ownArtificial-man made way of
reproducing plants using plant partsFlowering plants also reproduce
sexuallyTwo parent plants are needed
Day 1
+
Help conserve or increase the population of rare or endangered plants
Better crops in a shorter time period
Requires less care and attention
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
ADVANTAGES DISADVANTAGES

Natural Vegetative Reproduction
Asexual Reproduction in Plants
+Natural Vegetative Regeneration
Stems which grow underground Potato, ginger,
onion
UNDERGROUND STEMS
+Natural Vegetative Regeneration
Part of the stem that shoots uprightBanana, pineapple
and heliconia (birds of paradise)
SUCKERS
+Natural Vegetative Regeneration
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

Artificial Vegetative Reproduction
Asexual Reproduction in Plants
+Artificial Vegetative Regeneration
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
CUTTING
+Artificial Vegetative Regeneration
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
CUTTING
+Artificial Vegetative Regeneration
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
CUTTING
+Artificial Vegetative Regeneration
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
GRAFTING
+Artificial Vegetative Regeneration
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
BUDDING
+Artificial Vegetative Regeneration
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
AIR LAYERING

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