Introductory Horticulture: Softwood and Semihardwood Cuttings and Micropropagation

These flashcards focus on key terminology and concepts related to softwood and semihardwood cuttings and micropropagation techniques in horticulture.

Asexual Reproduction

A method of reproduction that does not involve the fusion of gametes, such as propagation via cuttings.

Cuttings

Parts of a plant, such as stems or leaves, that are used to propagate new plants.

Softwood Cuttings

Cuttings taken from young shoots that are still in active growth and are tender.

Semihardwood Cuttings

Cuttings taken from partially matured stems, often used for propagation.

Rooting Hormone

A substance applied to cuttings to promote root development.

Transpiration

The process by which moisture is lost from leaves to the atmosphere.

Humidity Control

Maintaining high humidity levels to reduce moisture loss in cuttings.

Micropropagation

A tissue culture technique used to produce large numbers of identical plants quickly.

Microsculture

A specific method in micropropagation involving small sections of plant tissue.

Herbaceous Cuttings

Cuttings taken from succulent, non-woody plants, typically requiring high humidity.

Drainage

The removal of excess water from the container to promote healthy root development.

Fungicide

A chemical used to prevent fungal growth, particularly important for cuttings.

In Vitro Soil (IVS)

A new propagation system where plant tissue is grown in a sterile environment.

Leaf Cuttings

A method of propagation where leaves are used to grow new plants.

Root Cuttings

Cuttings taken from roots to propagate new plants, typically 1/8 to 1/2 inch in diameter.
