Slide1Objective 20.02• Discuss methods of asexual propagation using plants that are typically reproduced asexually
Slide2Propagation• Increasing the number of a plant species or reproduction of a species
Slide3Sexual Propagation• Use of seed for reproducing plants • Only way to obtain new varieties • Increase hybrid vigor of plants • Less expensive • Quicker than other methods
Slide4Asexual Propagation• Use of a part or parts of a plant for reproducing plants • Also called vegetative propagation • The new plant is an exact duplicate of the parent plant
Slide5Methods of Asexual Propagation• Cuttings are vegetative parts that the parent uses to regenerate itself • Examples: – Leaf cuttings – Root cuttings – Stem cuttings
Slide6Methods of Asexual Propagation(Continued) • Rooting hormone: a substance applied to cuttings to speed up the root development.
Slide7•Layering a method where the stem is encouraged root while still attached to the parent plant • Examples: – Simple layering – Tip layering – Air layering Methods of Asexual Propagation (Continued)
Slide8Air layering• Propagation method where a stem is girdled, treated with a rooting hormone, and surrounded with damp sphagnum moss and plastic until new roots appear.
Slide9Methods of Asexual Propagation(Continued) • Division: by dividing or separating the main part of the plant into small parts • Examples: – Day lilies
Slide10Methods of Asexual Propagation(Continued) • Grafting: joining two plants together as they grow as one – T-budding is the most common type
Slide11Methods of Asexual Propagation(Continued) • Root cutting: a type of cutting made when the plant is dormant and its roots have a reserve of carbohydrates • Can harm parent plant • Examples: – Roses – Blackberries – lilacs
Slide12•Tissue culture or micropropagations: the use of very small and actively growing parts of the plant to produce a high number of new plants – Cloning is achieved by tissue culture Methods of Asexual Propagation (Continued)
Slide13Seeds• Result of sexual reproduction • Viable: a seed that is alive and capable of germination
Slide14That’s all folks…
