Plant Propagation
Chapter 5
Learning Targets
 I can identify various 2 types of Plant
Propagation?
 I can identify 2 and explain ways of
seeding?
Plant Propagation
 Reproduction of new
plants from seeds or
vegetative parts of
plants.
Sexual Propagation
 Reproduction of
plants with the use
of seeds.
Seedlings
 Plants grown from
seeds.
Seed Production
 Located in North
Pacific
 Dry Climates
 Less Disease
Harvesting and Storing
Seeds
 Seed harvested to
soon or to late will
reduce
germination.
Harvesting Seed
Techniques
 Mechanical
Equipment
Harvesting Seed
Techniques
 Hand Harvesting
Cleaning Seeds
 To prepare seeds
for the following
years crop.
Cleaning Seeds
 Hand Cleaning
with water.
Cleaning Seeds
 Mechanical
Cleaning
Storing Seeds
 Store in a Cool
Dry Place.
 Glass Jar
 Plastic Bag
 Try and use all
seed the following
year.
Testing and Labeling of
Seeds
 Best seed saves
time and money.
 State Law
Regulates
shipment of sales
of seed.

Percent Germination
 % of seeds that
will sprout and
grow.
Percent Germination Test
 Place seeds on
towel. 100 seeds
 Keep moist
 Keep at 85 Deg.
 Count number of
seeds that sprout.
 80 out of 100
Germinate = 80%
Direct Seeding
 Seeds are planted
directly into the
soil.
 Plants easily
germinated.
Direct Seeding Examples
 Flowers
 Vegetables
 Lawn Seed
Success of Direct Seeding
5-Factors
 Site Selection
 Seedbed
Preparation
 Planting Date
 Planting Depth
and Space
 Moisture
Indirect Seeding
 Seeds that are
planted in
greenhouses.
 Planted in Flats or
Containers
Seed Coat Dormancy
 The seed coat will
not allow moisture
to the seed.
Scarification
 Seed coat is
broken or
softened.
Embryo Dormancy
 Seeds must be
cooled in soil at
32-50 deg.
Stratification
 Seeds must be
kept cool for a
certain period of
time.
Germination Media
 Plastic Containers
 Peat Pots
 Needs proper
drainage and
aeration
Seed Flats
 Soil needs to be
level.
 Water soil and
allow to drain.
Planting in Rows
 Advantages:
 Easy
Transplanting
 Reduced chance
of disease
 Disadvantages
 Takes more space

Adv:
Easy to do
Less Expense
Disadvantage:
Harder to observe
Less chance of
germination
Mechanical Seeding
 More expensive
 More accurate
seeding rate
Asexual Propagation
 Reproduction of
new plants from
the stem, leaves,
or roots of a
parent plant.
 Clone Plant
Stem Cuttings
Leaf Cuttings
Root Cuttings
