Asexual Types of Plant Propagation
Many plant propagation techniques are asexual. The most common methods of asexual propagation include cuttings, layering, and division.
Cuttings plant propagation techniques ...
Asexual Reproduction: Reproduction without fertilisation, especially relevant to cuttings and other types of vegetative reproduction.
Auxins: A natural or artificial substance controlling the growth of shoots, roots, etc.
Asexual Reproduction - Reproduction by one sex via budding, fission, etc. resultant in genetically identical offspring.
Atom - A unit of matter consisting of electrons, protons, neutrons, and other subatomic particles.
Asexual propagation multiplying plants without use of seeds
Attenuate Showing a long gradual slender taper; usually applied to apices, but equally appropriate for bases of leaves, petals, etc.
ASEXUAL - This is a means of propagation that does not include seed production. Therefore propagating by cuttage, dividing and layering.
asexual reproduction See vegetative propagation.
aspect Direction of exposure to sunlight.
assimilation The building of cell matter from inorganic and organic materials (carbohydrates and sugars).
Asexual propagation is the best way to maintain some species, particularly an individual that best represents that species. Clones are groups of plants that are identical to their one parent and that can only be propagated asexually.
Asexual propagation is also referred to as 'vegetative propagation.' Where the seed is actually part of the plant's reproductive system, vegetative propagation uses plant parts that aren't typically part of the reproductive system - like the leaves, ...
ASEXUAL -- Vegetative reproductions - e.g. cuttings and division.
BARE-ROOT -- Usually referring to deciduous shrubs and trees, and some other perennials, with all the soil removed from their roots that are sold at nurseries.
ASEXUAL: Vegetative reproductions - i.e. cuttings and division.
ATRIUM: A structure that provides lots of above light for plants. Commercial buildings often have their foyer as an atrium. Many homes have built in atriums.
asexually (asexual spore) or by the union of gametes (sexual spores); they are highly resistant and are capable of giving rise to a new adult individual, either immediately or after an interval of dormancy.sporophyte search for term- n. (Gr.
The term cultivar (short for cultivated variety) identifies a plant variety that has been created by horticultural techniques such as cross-breeding or selection, and is perpetuated asexually to preserve its outstanding characteristics.
clone A genetically identical plant resulting from asexual propagation (cuttings, layering, grafting, or tissue culture). conic Cone shaped, conical convex Curved outward.
Clones are the result of asexual or vegetative propagation, whereas, seeds are the result of sexual propagation.
Wingless adult females bearing live young are found on apple trees during the summer (see bottom of asexual life cycle). This adult form is dark brown to purplish, and 1.8 mm (.07 in.) long.
Vegetative, or asexual, propagation is much simpler. It involves taking parts of a fern or young plants that have grown by a bud directly from the parent fern and planting them. The resulting new plants mature quickly.
Propagation via cuttings is a vegetative or asexual method of reproduction. This means that all new plants will be genetically identical to one another and to their parent plant. Seed raising is a sexual method of reproduction.
Cutting -a. growing tip cut from a parent plant for asexual propagation b. clone

Damping-off - fungus disease that attacks young seedlings and cuttings causing them to rot at the base: Over-watering is the main cause of damping-off.
The all-male varieties (Jersey Giant, Jersey Knight) produce more spears, but only reproduce asexually, thus limiting the life span of the asparagus bed.
Best zonal geranium was 'Designer Hot Pink' from Ball FloraPlant. These geraniums were propagated asexually from cuttings.
conidium (plural: conidia). A type of asexual fungal spore.
control action guideline. A guideline used to determine if pest control action is needed.
Growing plants from cuttings is vegetatively or asexually reproducing the plant, so that the resulting plant will have the same traits of the mother plant.
It is caused by the fungus Nectria cinnabarina (Tode) Fr., asexual state of Tubercularia vulgaris Tode. Recognition of the disease is important because it is often confused with fire blight, which requires different control measures.
Also, small black dots, asexual fruiting structures begin forming. Infection spots (lesions) usually do not appear on fruits until after they are half grown. The first symptom is the appearance of very small whitish areas on developing green fruit.
Furthermore, insects studied aboard spacecrafts have had very difficult times adapting to the zero gravity environment. Researchers are forced to devise alternative methods of pollination or rely on self-pollinating or asexual plants.
Cultivars refers to varieties which, although they occurred naturally, can only be replicated by asexual propagation and human intervention by cloning.
