Question

Grafting results in

• A. Mixing of traits of two varieties without resorting to hybridisation
• B. Providing hormones and stimulating chemicals from stock to scion
• C. Quick growth of desirable variety with poor root system
• D. All the above

Answer 1

Answer: (A)

Mixing of traits of two varieties without resorting to hybridisation

Grafting is a horticulture technique where the living detached portion of the plant is used to regenerate the growth. One plant is selected for its roots and this is called the stock or rootstock. The other plant is selected for its stems, leaves, flowers, or fruits and is called the scion. The joining of scion and stalk is known as inosculation.

Grafting involves mixing of traits of two varieties without resorting to hybridization as because stock and scion belong to two different plant species. The vegetative part is developed by the scion so fruit, flowering, branching, and leaves pattern depends on scion while the root pattern is influenced by the genome of the stock.

So, the correct answer is option A.
