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.
Seed Label Tag
Information
Trueness of name
Origin
Germination %
Pure Seed %
Weed Seeds %
Inert Materials %
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
Broadcasting Seeds
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
