Ch. 40 - Vegetative Propagation Flashcards
What is vegetative propagation?
Vegetative propagation is asexual reproduction in plants.
What is natural vegetative propagation?
Natural vegetative propagation involves forming new plants from a stem, root, leaf or bud.
What are runners?
Runners are horizontal stems that grow above ground from which new plants grow. Strawberries use runners.
What plants are propagated from leaves?
Begonia, cacti.
What is a root tuber?
A root tuber is a swollen, underground root that remains dormant during winter from which new plants may grow. Sweet potatoes have root tubers.
What is a bulb?
A bulb is a modified bud.
Name 4 methods of artificial vegetative propagation.
Cuttings, grafting, layering and micropropagation.
What is a cutting?
A cutting is the removal of a portion of a parent plant to grow a new, independent plant.
What is grafting?
Grafting is the joining and uniting of part of one plant with a second plant.
What is layering?
Layering is the growth of a new plant from a stem that is still attached to the parent plant.
What is micropropagation?
Micropropagation is the growth of plants from small pieces of tissue under sterile conditions on a specifically selected medium.
What are advantages to vegetative propagation?
New plants form fast. New plants are the identical to the parents.
What are disadvantages to vegetative propagation?
There is a lack of variation. Diseases can be passed from parent to offspring. Plants may lack vigour.
