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.

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 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
