Plant Grafting: New Mechanisms, Evolutionary Implications


Plant Grafting: It is a technique of horticulture where you improve your plant by joining parts of two or more plants so that they appear to be growing as a single plant. In grafting, the upper portion of one plant grows on the roots of another plant. It is a process in which two separate plants connected to grow as one plant. Grafting benefits in combining the qualities of both types of plants into one. Suppose, the upper portion of the plant bears colorful flowers, and the roots of the other plant are disease-resistant. If we graft both of them, the plant will now do both, take colorful flowers as well as have disease-resistant roots. Trees like Apple, Camellia, Cherries, etc. can go within the method of grafting.

Grafting is done for several reasons, mainly to add plant matter to another plant, some of the reasons are as follows.

Adding a hardy root stock to a less hardy variety in order to get a more ornamental variety to grow in a more temperate region. Adding a productive root stock, to a better quality fruit producing variety, to get better fruit, also grafting another variety of fruit to an existing one, so you get Victoria and green gage plums on the same tree. Other types of grafting include bud grafting. This is in use in the hobby of Bonsai. In this example, if you wish to grow a new branch on a tree, where is not one (for aesthetic reasons), you can graft a bud in the place you wish. And when successful, the bud will form the bases of a new branch. This is a basic answer, and like most things in Horticulture you can dabble in it, or get deeply involved and more complex.

Introduction of New Mechanisms

There are different types of traditional grafting methods.

  • Cut grafting
  • Cleft grafting
  • Crown grafting
  • Splice grafting
  • Tongue grafting
  • Approach grafting

In the past few years, a lot of new mechanisms of plant grafting have. Genetic homogeneity and graft adaptability and variance checked. Root top interactions have done very carefully. Protein and RNA signals passed in between the plants. Grafting helps in conquering the most harmful plant inflammations and pests.

Shortcomings of Plant Grafting

As I discussed before, Other types of grafting include bud grafting, which is used in the hobby of Bonsai in this example, if you wish to grow a new branch on a tree, where is not one (for aesthetic reasons), you can graft a bud in the place you wish, and when successful, the bud will form the bases of a new branch.

As this is an artificial process, it has drawbacks. Grafting leads to the damage of a plant portion from which the part separated. It leads to decaying a plant. It’s a very time-consuming process. Basically, a lot of different equipment is in use, which may not be available all the time. There are certain risks which come hand in hand with grafting. However, the graft may be incompatible and die after being cut. But the process overall is a beneficial one. Thus, it has positive effects on the environment and nature more than the adverse effects
