Objectives: • You will be able to identify the areas on a plant from which cuttings may be taken. • You will be able to recognize materials, plants, and chemical hormones needed for successful plant propagation by cuttings.
Objectives Continued: • You will be able to demonstrate the ability to take cuttings off plants, and place them in a potting medium. • You will be able to determine if successful root formation occurs.
What is asexual plant propagation? • It is the production of offspring by use of vegetative parts, rather than a seed of a plant used to produce a new plant.
Why would you want to use asexual plant propagation? • Plants are produced quicker • Disease free stock • Plants will be genetically identical to their parents. • Cost • Plants with or without reproductive parts can be produced.
Cuttings: • Where can cuttings be taken from? • Roots • Stems • Leaves • Modified Stems
Materials: • Plants • Rooting Hormone (Auxin) • Scissors • Plant Pot • Soil • Four Popsicle Sticks
Safety Reminder: • Be extremely careful when using the scissors to take cuttings. • Avoid contact with skin, eyes, and clothing when using the rooting hormone. • Remember no horseplay in the lab. • Share all materials.
Taking Cuttings: • Root Cuttings- cut into 2-3 in sections. • Stem Cuttings- cut a small portion of the stem with node. Make sure to cut the stem at an angle. (surface area) • Modified Stem- Each cutting must have an “eye” or thickened area for root and shoot development.
Taking Cuttings Continued: • Leaf Cuttings- • Leaf- Petiole- will include both the leaf and the petiole. • Leaf Section – will consist of a section of the leaf either cut radiantly down the center or horizontally.
Application • Collect 4 cuttings from the plants • One leaf cutting • One stem cutting • One modified stem cutting • One plantlet
Application Continued: 2. Fill a pot with potting soil 3. Dip each individual plant in the rooting hormone. • Plant the plants in the pots. • Label each type of plant and identify the type of cutting. • Place pots in the greenhouse for further evaluation.
Summary • We identified the areas from which cuttings may be taken. • We discussed materials, plants, and chemical hormones needed for successful plant propagation by cuttings. • We took cuttings from plants and placed them in a potting medium.
Summary Continued: • We placed the cuttings in the greenhouse for further evaluation to determine if root formation occurs.
