C10L3P1

2. Asexual Reproduction
Asexual reproduction occurs when a portion of a plant develops into a separate new plant that is genetically identical to the original, or parent, plant.

3. Asexual Reproduction little genetic variation
has genes identical to its parent’s

4. Advantages of Asexual Reproduction
identical plants
saves time
saves money

6. Vegetative Propagation
The growth of a new plant from a stem, leaf, or root (something other than a seed).

7. Vegetative Propagation induced
Man growing a new plant from a root, stem, or leaf.

8. Types of Vegetative Propagation that are induced
cuttings (or slip)
layering
grafting

9. Cuttings
A piece of a stem, leaf, or root which is capable of growing into a new plant.

10. Cuttings
Cuttings are possible because certain types of plants are able to sprout special types of roots at the cut end of their stems. Adventitious roots
When a yellow-flower- ing hedge shrub is trimmed, a new shrub may be started by simply sticking a trimmed stem into the ground.

11. Layering
A branch is exposed to the soil, allowed to form roots, and then separated from the parent plant.
Vineyards use this method to quickly reproduce a desirable variety of grapes.

14. Grafting
The process of transplanting living tissue from one plant to another.
Used to propagate seedless plants: grapes, navel oranges

15. This tree was developed by the West family in New South Wales, Australia and the process involves grafting branches
Grafting
from compatible fruit trees onto one. The result is 4 different trees each with there own variety of fruit.

16. For example there is a stone fruit tree with apricots, peaches, plums, nectarines and peachcots; a citrus tree with oranges, mandarins, lemons, limes,
Grafting
tangellos, grapefruit; a multiple apple tree, and a pear tree.

17. Types of Vegetative Propagation that are natural
underground stolons (mints)
rhizomes (cattails)
corms (gladiolus)
bulbs (onion)
tubers (Irish potatoes)
runners (strawberries)
