Propagation by stem cuttings is the most commonly used method to propagate many woody ornamental plants. Stem cuttings of many favorite shrubs are quite easy to root. Typically, stem cuttings of tree species are more difficult to root. However, cuttings from trees such as crape myrtles, some elms, and birches can be rooted.

The somatic propagation of trees has an edge over raising of stock through seeds. These techniques have also become important in forestry owing to their potential in propagating trees, which possess superior traits, in an effort to increase volume and quality of production.
Methods of vegetative propagation can be broadly classified as macro propagation and micro propagation techniques. There are three main methods of macro propagation used in trees: cuttings, grafts and layers. Latest in vegetative propagation of trees is the micro propagation through tissue culture techniques.
The rootstock of grafted trees is selected because it propagates easily, so these trees may often send up tree shoots at the base of the tree.
These reasons are to help the tree survive transplanting, to stimulate growth and to shape it so the root system can support the branches.

The vegetative propagation of elite trees is central to the domestication strategy for indigenous trees producing valuable and marketable products (leakey and akinnifesi, 2008). A key element of this strategy is that the domestication is done by local people in their communities so that they are the beneficiaries of their work.

The book which is the first one in the romanian specialized literature, deals with the most outstanding and modern issue of vegetative propagation of forest trees as well as its implica- tions in practical forestry.
Archangel’s early experimentation with propagation led to scientific success in cloning the oldest and largest trees in existence. Prior to aata’s work, the scientific community believed that several thousand year old trees could not be cloned through propagation and were no longer viable for impacting climate change.
This practice of vegetative propagation of fruit trees dates back to ancient times. China had been using grafting techniques since pre-classical times. The greeks and romans adopted this strategy and spread these methods all over europe. Sexual reproduction of fruit trees is a rarely used method in horticulture.

Intensive culture of short rotation forest crops or the large scale replanting of forest land with selected, superior trees will depend on techniques for their practical, rapid, clonal, mass propagation. Standard methods of vegetative propagation can be used to multiply planting stock of some species, but they are not successful with many woody plant species.

These systems include a multitude of fruit trees, livestock, annual crops, medicinal plants, and high value multipurpose forest trees. It has been suggested that the frequently haphazard multi-strata systems may be an attempt of farmers in the tropics to mimic the natural ecosystems and in order to minimize risk (leakey, 1999).

The two most common ways to propagate plants are by seed or vegetative cuttings (stem, root, leaf, or tissue culture). While seeds preserve genetic diversity and give rise to new varieties, vegetative propagation can clone and preserve existing varieties.
Trees who share a mycorrhizal network, like the birch (left) and fir (right), are able to send nutrients to each other or signal to each other in times of stress. Trees rely on a healthy forest ecosystem to thrive and protect themselves from danger.

The three main types in forest tree propagation are grafting, air-layering and the use of cuttings. The three types are referred to as macropropagation, as alternative to micropropagation or tissue culture. Propagation by cuttings is the most convenient and cheapest method and usually preferred when possible.

As the distance between the transmitter and the receiver is very long, the radio wave propagation through the stratified forest is characterized by the lateral wave that mainly propagates on top of the canopy along the air-canopy interface. For short distances, however, such a propagation is denominated by the direct or coherent component.
Most native plants used for ecosystem conservation and restoration are propagated exclusively from seeds. Sufficient quantities of seeds are needed to restore and sustain native plant communities that are increasingly affected by invasive species, pest infestations, wildfire, and climate change. The national seed laboratory (nsl) is currently addressing these complex challenges and is serving as the primary national strategic resource for forest ecosystem seed science and technology.
