It can be seen on the enlarged trunk: The ability to induce fruitfulness without the need for completing the juvenile phase.

The history and the process of grafting

Juvenility is the natural state through which a seedling plant must pass before it can become reproductive. In most fruiting trees, juvenility may last between 5 and 9 years, but in some tropical fruits e.

Mangosteenjuvenility may be prolonged for up to 15 years. Grafting of mature scions onto rootstocks can result in fruiting in as little as two years. To induce dwarfing or cold tolerance or other characteristics to the scion.

Most apple trees in modern orchards are grafted on to dwarf or semi-dwarf trees planted at high density. They provide more fruit per unit of land, higher quality fruitand reduce the danger of accidents by harvest crews working on ladders.

Care must be taken when planting dwarf or semi-dwarf trees. If such a tree is planted with the graft below the soil, then the scion portion can also grow roots and the tree will still grow to its standard size. Because the scion is difficult to propagate vegetatively by other means, such as by cuttings.

In this case, cuttings of an easily rooted plant are used to provide a rootstock.

In some cases, the scion may be easily propagated, but grafting may still be used because it is commercially the most cost-effective way of raising a particular type of plant.

To speed maturity of hybrids in fruit tree breeding programs. Hybrid seedlings may take ten or more years to flower and fruit on their own roots.

Grafting can reduce the time to flowering and shorten the breeding program. Because the scion has weak roots or the roots of the stock plants are tolerant of difficult conditions. Grevilleas and eucalypts are examples. To provide a strong, tall trunk for certain ornamental shrubs and trees.

In these cases, a graft is made at a desired height on a stock plant with a strong stem. A major example is the use of rootstocks in combating Phylloxera. For example, in tightly planted or badly planned apple orchards of a single variety, limbs of crab apple may be grafted at regularly spaced intervals onto trees down rows, say every fourth tree.

This takes care of pollen needs at blossom time, yet does not confuse pickers who might otherwise mix varieties while harvesting, as the mature crab apples are so distinct from other apple varieties.

To repair damage to the trunk of a tree that would prohibit nutrient flow, such as stripping of the bark by rodents that completely girdles the trunk. In this case a bridge graft may be used to connect tissues receiving flow from the roots to tissues above the damage that have been severed from the flow.

Where a water sproutbasal shoot or sapling of the same species is growing nearby, any of these can be grafted to the area above the damage by a method called inarch grafting. These alternatives to scions must be of the correct length to span the gap of the wound.

To change the cultivar in a fruit orchard to a more profitable cultivar, called top working. It may be faster to graft a new cultivar onto existing limbs of established trees than to replant an entire orchard.

Apples are notorious for their genetic variability, even differing in multiple characteristics, such as, size, color, and flavor, of fruits located on the same tree. In the commercial farming industry, consistency is maintained by grafting a scion with desired fruit traits onto a hardy stock.

An example of approach grafting by Axel Erlandson. Curiosities A practice sometimes carried out by gardeners is to graft related potatoes and tomatoes so that both are produced on the same plant, one above ground and one underground.

Cacti of widely different forms are sometimes grafted on to each other. Multiple cultivars of fruits such as apples are sometimes grafted on a single tree.Fat grafting, also referred to as fat transfer or fat injections, is the surgical process by which fat is transferred from one area of the body to another area.

The surgical goal is to improve or augment the area where the fat is injected. Fat grafting, also referred to as fat transfer or fat injections, is the surgical process by which fat is transferred from one area of the body to another area.

In fact, it is unlikely that grafting was invented de novoby early agriculturists, but rather, the earliest deliberate grafting was almost certainly based on observation of spontaneous grafting observed in nature.

During WWI and WWII, bone grafting continued to develop as more soldiers became crucially wounded and a need for advanced surgeries became necessary.
