Only a small number of layers can be produced from a parent plant than when the same plant is used as a source of cuttings, buds, or scions.ģ. This method is laborious and therefore expensive.Ģ. Disadvantages of Air Layering Compared to Other Vegetative Propagation Methodsġ. In mature calamansi or calamondin layered shoots continue bearing fruits. Larger plants that are readily mature can be produced in a faster time. With a small number of plants, it can produce more layers with less skill, effort, and equipment.ģ. Air layering or marcotting is relatively simple to perform. ![]() Rooting success is more ensured through layering, including clones that will not root easily.Ģ. ![]() Advantages of Air Layering Compared to Other Vegetative Propagation Methodsġ. In monocot plants such as bamboo, aglaonema, dieffenbachia, and dracaena, the roots emerge from the node. Prostrate stems of some plants which naturally root at the point of contact with the soil indicate that these plants can be easily rooted using this method, as with stem cuttings. In general, plants that can be propagated using stem cuttings will also root through air layering. Rooting success likewise depends on the plant species. This can be applied in powder form, lanolin, or as a dilute solution. The application of rooting hormone to the injured stem is sometimes effective. It has been observed also that the rainy season favors rooting rather than the hot, dry season.Ĭroton or san francisco (Codiaeum variegatum) can be easily rooted by air layering These conditions can be provided by using a loose rooting medium with high water holding capacity such as sphagnum moss. These materials accumulate close to the treated area and induce rooting.Ĭontinuing availability of moisture, sufficient supply of oxygen (aeration), and moderate temperature in the part of the stem where roots are to form can affect the formation of roots on layers or marcots. These generally involve the girdling or wounding of a small part of the stem, resulting in the interruption of the downward movement of organic materials such as carbohydrates, auxin, and other growth factors from the leaves and shoot tips. The formation of adventitious roots during air layering is induced by various stem treatments. Examples of Important Crops That Have Been Layeredīell fruit, water apple, or tambis ( Syzygium aqueum), black pepper ( Piper nigrum), cacao ( Theobroma cacao), cashew ( Anacardium occidentale), citrus ( Citrus spp.), coffee ( Coffea spp.), grape ( Vitis vinifera), guava ( Psidium guajava), jackfruit ( Artocarpus heterophyllus), lanzones or langsat ( Lansium domesticum), lychee ( Litchi sp.), mangosteen ( Garcinia mangostana), pili nut ( Canarium ovatum), sapodilla or chico or chickle tree ( Manilkara zapota), starapple or caimito ( Chrysophyllum cainito), soursop ( Annona muricata) and tamarind ( Tamarindus indica). ![]() This propagation method applies to many trees, shrubs, bamboo, and herbaceous plants. It is one among the various special methods of layering which also include tip layering, simple layering, compound or serpentine layering, mound or stool layering, and trench layering. Air layering, also called marcotting, marcottage, pot layerage, circumposition, and gootee, is a vegetative method of plant propagation that involves the rooting of aerial stems while attached to the parent plant.
