Describe the proccess of vegetative propagation?
Vegetative propagation is a type of asexual reproduction by which offspring are derived from one parent, therefore the offspring is technically a clone of the parent plant. Vegetative propagation is a way for farmers to get the exact plant they wish to cultivate from a previous plant with desired traits. The "eyes" of potatoes can be cut out and planted to form more potatoes exactly like the parent plant. A cutting, another method of vegetative propagation, usually is derived from the stem or leaves of a plant. Eventually, roots will develop and an independent plant will grow. Runners are another type of vegetative propagation when a stem sends off a sideways branch above ground, which develop into another plant, wherever it touches down. Strawberries and many types of weeds spread by runners. Rhizomes are underground stems that send sideways branches that will form additional plants. Bulbs, as in daffodils, onions, garlic and tulips can be separated into individual bulbs and re-planted to give rise to more offspring that are identical. Tubers are underground stems or roots that are fleshy and can give rise to more offspring. All of the seedless varieties of fruits we see in the market are the result of vegetative propagation. A mutation occurred causing a seedless variety of fruit. In order for a farmer to continue to produce this variety, she would need to make cuttings of this plant and continue to propagate it or it would die when the plant died. All of these methods are examples of vegetative propagation.
Vegetative propagation is a form of nonsexual reproduction in plants. Unlike sexual reproduction, the new plant is the result of one single parent plant. Also, both plants (parent and child) are genetically identicial. Through vegative propagation, a person can raise a plant much faster than growing one from a seed.
There are two types of vegetative propagation: natural and artificial. In natural vegetative propagation, the new plant grows from part of the parent plant. This includes runners from the stem, tubers from the roots, plantlets from the leaves, and from a parent bulb. Artifical vegetative propagation is done by farmers and gardeners by artifical (not natural) means. This can include cuttings from a parent plant, grafting two plants together, or layering (which involves burying a stem to create a new plant).
