Layering is a technique for plant propagation in which a portion of an aerial stem is encouraged to grow roots while still attached to the parent plant, and then removed and planted as a new plant. Plant propagation is the process of artificially or naturally propagating (distributing or spreading) plants. ... In common parlance, a stem is any elongated, usually narrow, extension or supporting structure of an object. ... Primary and secondary roots in a cotton plant In vascular plants, the root is that organ of a plant body that typically lies below the surface of the soil (compare with stem). ...
The process typically involves wounding the target region and optionally applying rooting compounds. In ground layering, the stem is bent down and the target region buried in the soil. In air layering, the target region is surrounded in a moisture-retaining wrapper such as sphagnum moss, which is further surrounded in a moisture barrier such as polyethylene film. In either case, the rooting process may take from several weeks to a year. IAA appears to be the most active Auxin in plant growth. ... Species See text Sphagnum is a genus of mosses commonly called peat moss due to its prevalence in peat bogs. ... Polyethylene or polyethene is an engineering thermoplastic heavily used in consumer products. ...
Layering is more complicated than taking cuttings, but has the advantage that the propagated portion can continue to receive water and nutrients from the parent plant while it is forming roots. This is important for plants that form roots slowly, or for propagating large pieces. Cutting is the separation of a physical object, or a portion of a physical object, into two portions, through the application of an acutely directed force. ... Water (from the Old English word wæter; c. ... Nutrients and the body A nutrient is any element or compound necessary for or contributing to an organisms metabolism, growth, or other functioning. ...
Layering is a technique for plant propagation in which a portion of an aerial stem is encouraged to grow roots while still attached to the parent plant and then removed and planted as an independent plant.
Ground layering is the typical propagation technique for the popular Malling-Merton series of clonal apple rootstocks in which the original plants are set in the ground with the stem nearly horizontal, which forces side buds to grow upward.
In airlayering, the target region is wounded and then surrounded in a moisture-retaining wrapper such as sphagnum moss, which is further surrounded in a moisture barrier such as polyethylene film.
