Purposes for Plant Propagation
• Multiply the number of a species
• Perpetuate a species
• Maintain the youthfulness of a plant
![Page 3: Introduction to Plant Propagation - CTAHR Website · Introduction to Plant Propagation Glenn T. Sako Assistant County Extension Agent CTAHR, UHM. Purposes for Plant Propagation •](https://reader030.vdocuments.us/reader030/viewer/2022040302/5e8114eb57f666705d0a847a/html5/thumbnails/3.jpg)
Types of Propagation
• Sexual (seed)– Involves floral parts of the plant
– Union of pollen and egg
• Asexual (vegetative)– Regenerate part of a parent plant into a new plant
– Genetically identical to its one parent
– Involves stems, roots, or leaves
![Page 4: Introduction to Plant Propagation - CTAHR Website · Introduction to Plant Propagation Glenn T. Sako Assistant County Extension Agent CTAHR, UHM. Purposes for Plant Propagation •](https://reader030.vdocuments.us/reader030/viewer/2022040302/5e8114eb57f666705d0a847a/html5/thumbnails/4.jpg)
Seed Advantages
• Produce large number of seedlings from asingle parent plant
• May store seeds for future propagation
• Breed for new varieties and hybrid vigor
• Avoid transmission of certain diseases
![Page 5: Introduction to Plant Propagation - CTAHR Website · Introduction to Plant Propagation Glenn T. Sako Assistant County Extension Agent CTAHR, UHM. Purposes for Plant Propagation •](https://reader030.vdocuments.us/reader030/viewer/2022040302/5e8114eb57f666705d0a847a/html5/thumbnails/5.jpg)
Seed Disadvantages
• Genetic material may not be uniform
• Cannot save seeds from hybrids
• Long time to sizable plant– Woody plants and shrubs
• Irritants in fleshy covering (palms, etc.)

Seed Storage
• Keep in sealed container
• Refrigerate @ 400F
• Low humidity
• Viability can approach 5 years– Varies with species
– Viability will decline
• Check germination % of stored seeds prior to planting
![Page 11: Introduction to Plant Propagation - CTAHR Website · Introduction to Plant Propagation Glenn T. Sako Assistant County Extension Agent CTAHR, UHM. Purposes for Plant Propagation •](https://reader030.vdocuments.us/reader030/viewer/2022040302/5e8114eb57f666705d0a847a/html5/thumbnails/11.jpg)
Factors that affect Germination• Water – imbibition• Oxygen – respiration takes place in all viable
seeds• Light
– requires light: impatiens, petunias, lettuce– requires dark: pansy
• Temperature – some seeds have optimal temperatures for germination
![Page 12: Introduction to Plant Propagation - CTAHR Website · Introduction to Plant Propagation Glenn T. Sako Assistant County Extension Agent CTAHR, UHM. Purposes for Plant Propagation •](https://reader030.vdocuments.us/reader030/viewer/2022040302/5e8114eb57f666705d0a847a/html5/thumbnails/12.jpg)
Seedling Media Requirements
• Particle size should be fine and uniform
• Well drained
• Free of insects, disease, & weed seeds
• Low in total soluble salts
• Avoid soil from the garden
– Heavy, not sterile
![Page 13: Introduction to Plant Propagation - CTAHR Website · Introduction to Plant Propagation Glenn T. Sako Assistant County Extension Agent CTAHR, UHM. Purposes for Plant Propagation •](https://reader030.vdocuments.us/reader030/viewer/2022040302/5e8114eb57f666705d0a847a/html5/thumbnails/13.jpg)
Transplanting Seedlings
• When young plants less susceptible to shock (transplant shock)
• Usually when 1st true leaves appear
• Can be left longer when grown in cell packs or individual containers
• After transplanting, wait 1-2 weeks before fertilizing at a low rate

Asexual (Vegetative) Propagation• Cuttings
– Rooting a severed piece from a parent plant
• Layering – Rooting a stem while attached to the parent plant
• Division – Separation of multi-crown plants
• Grafting & Budding – Joining of 2 plant parts
• Tissue Culture – Aseptic culture of meristematic tissue
![Page 19: Introduction to Plant Propagation - CTAHR Website · Introduction to Plant Propagation Glenn T. Sako Assistant County Extension Agent CTAHR, UHM. Purposes for Plant Propagation •](https://reader030.vdocuments.us/reader030/viewer/2022040302/5e8114eb57f666705d0a847a/html5/thumbnails/19.jpg)
Vegetative Advantages
• Larger, fuller plant produced faster
• Genetically, same as the parent
• Only way to propagate some species
• Bypasses juvenile characteristics
![Page 20: Introduction to Plant Propagation - CTAHR Website · Introduction to Plant Propagation Glenn T. Sako Assistant County Extension Agent CTAHR, UHM. Purposes for Plant Propagation •](https://reader030.vdocuments.us/reader030/viewer/2022040302/5e8114eb57f666705d0a847a/html5/thumbnails/20.jpg)
Vegetative Propagation Concerns
• Time spent collecting and preparingvegetative material
• May need structures and water
![Page 21: Introduction to Plant Propagation - CTAHR Website · Introduction to Plant Propagation Glenn T. Sako Assistant County Extension Agent CTAHR, UHM. Purposes for Plant Propagation •](https://reader030.vdocuments.us/reader030/viewer/2022040302/5e8114eb57f666705d0a847a/html5/thumbnails/21.jpg)
Cuttings
• Many new plants from few stock plants, in alimited space
• Need structure and water– Can be simple
• Some plant material are difficult to root– Wounding
– Rooting hormone

Division
• Severing of rhizomes, tubers, & tuberous roots
• When bulblets or cormels detach naturally it is called separation
![Page 62: Introduction to Plant Propagation - CTAHR Website · Introduction to Plant Propagation Glenn T. Sako Assistant County Extension Agent CTAHR, UHM. Purposes for Plant Propagation •](https://reader030.vdocuments.us/reader030/viewer/2022040302/5e8114eb57f666705d0a847a/html5/thumbnails/62.jpg)

Grafting and Budding
• Joining of plant parts– fruit trees
• Utilized when other propagation methods fail
• Rootstock– Provides vigor for better quality
– Disease resistance
– Characteristics extended to grafted scion wood.
• Budding –when only single bud utilized
![Page 64: Introduction to Plant Propagation - CTAHR Website · Introduction to Plant Propagation Glenn T. Sako Assistant County Extension Agent CTAHR, UHM. Purposes for Plant Propagation •](https://reader030.vdocuments.us/reader030/viewer/2022040302/5e8114eb57f666705d0a847a/html5/thumbnails/64.jpg)
Conditions for a Successful Graft
• Scion & Rootstock – Cambiums must be aligned with each other
– Be compatible
– Be at proper physiological stage (buds dormant)
• Graft union kept moist
– wrapped with grafting tape, waxed, etc.
