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.
Asexual Reproduction • little genetic variation • has genes identical to its parent’s
Advantages of Asexual Reproduction • identical plants • saves time • saves money
Vegetative Propagation The growth of a new plant from a stem, leaf, or root (something other than a seed).
Vegetative Propagation induced Man growing a new plant froma root, stem, or leaf.
Types of Vegetative Propagation that are induced • cuttings (or slip) • layering • grafting
Cuttings A piece of a stem, leaf, or root which is capable of growing into a new plant.
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.
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.
Grafting The process of transplanting living tissue from one plant to another. Used to propagateseedless plants: grapes, navel oranges
Grafting This tree was developed by the West family in New South Wales, Australia and the process involves grafting branches from compatible fruit trees onto one. The result is 4 different trees each with there own variety of fruit.
Grafting For example there is a stone fruit tree with apricots, peaches, plums, nectarines and peachcots; a citrus tree with oranges, mandarins, lemons, limes, tangellos, grapefruit; a multiple apple tree, and a pear tree.
Types of Vegetative Propagation that are natural • underground stolons (mints) • rhizomes (cattails) • corms (gladiolus) • bulbs (onion) • tubers (Irish potatoes) • runners (strawberries)
