Question

Discuss the purposes, advantages, and disadvantages of grafting and budding.

Answer 1

Answer:- Purpose of Grafting and Budding:-Grafting and budding are horticultural techniques used to join parts from two or more plants so that they appear to grow as a single plant. In grafting, the upper part (scion) of one plant grows on the root system (rootstock) of another plant. In the budding process, a bud is taken from one plant and grown on another.

Advantages of Grafting:-Grafting is an asexual plant propagation technique that joins two or more plants to create a single plant that has benefits of each contributing plant. Different grafting techniques are suited for various plant types. Typically, a shoot of one plant, called the scion, which contains several vegetative buds, is grafted onto the stem of another plant, called the stock, which contains its roots. The resulting grafted plant is stronger, more prolific and better able to withstand pests and diseases.

Disadvantages of Grafting:-Grafting techniques vary, depending on the plant you want to propagate. Knowledge of graft types and skill to perform them requires experience beyond basic gardening. You must use grafting tape or clips, which is an additional expense, to hold cut surfaces together. If you do not remove tape at the proper time, it can girdle the stem and thwart your grafting efforts. Cut surfaces must align perfectly or the graft union will be unsuccessful. Tools need to be sterilized by flaming or dipping in alcohol or bleach to prevent transmitting disease. If the graft wound does not seal properly, it may cause undesirable shoots that grow below the union. Some plants, such as citrus types, must be protected from frost their first year when grafted in the fall. Until grafts “knit together” and nutrients flow freely from stock through scion, you must water plants sparingly so you don’t drown them.

Advantages of Budding:-Bud grafting, generally called budding, is similar to grafting. Instead of using a stem from one plant that contains several vegetative buds, only a single bud is grafted onto another plant’s rootstock. The result is called a budded plant. This method commonly produces roses, fruit trees, ornamental trees and shrubs. According to the University of California, budding is the most common method of propagating citrus trees. Budding allows many plants to be propagated from a single sample of scion wood.

Disadvantages of Budding:-The disadvantages of budding are the same as with grafting, with some notable additions. Since single buds are not as strong as stem sections, they are more susceptible to environmental pressures. Even birds may interfere with successful budding by breaking off buds as they land on stems. Even insects may interfere with successful budding by feeding on tender buds. Wrapping a single bud union with budding rubber or green horticultural tape requires precision. Nurse branches, which extend above the bud union, must be removed when new budwood grows leaves.
