Question

Rose is commercially propagated by _______.

• A. Bulbs
• B. Seed
• C. Tuber
• D. 'T' budding

Answer 1

The Correct Option is D

Rose is commercially propagated by a technique known as 'T' budding. 'T' budding is a form of vegetative propagation where a bud from the desired plant (scion) is inserted into a cut made on another plant (rootstock). The steps involved in 'T' budding include: 

1. Selection of Rootstock: Choose a healthy rootstock that is compatible with the desired rose variety.
2. Preparation of Scion Bud: Select a mature and healthy bud from the variety you wish to propagate.
3. Making the 'T' Cut: On the rootstock, make a vertical cut followed by a horizontal cut to form a ‘T’ shape.
4. Inserting the Bud: Carefully lift the bark at the cut and insert the scion bud.
5. Securing the Bud: Wrap the bud and the rootstock with budding tape to hold them together and protect the union.
6. After-Care: Ensure proper care by maintaining adequate moisture and monitoring for successful bud union.

This method is favored for its high success rate and the ability to produce plants identical to the parent, maintaining the desired characteristics of the rose variety.

Answer 2

Correct Answer: (D) 'T' budding

Rose plants are commercially propagated primarily through 'T' budding, a grafting technique where a bud from a desired rose variety is inserted into the rootstock of another rose plant. This method ensures the plant retains the desirable characteristics of the parent plant, such as flower color and fragrance, while benefiting from the rootstock's resistance to diseases and pests. Although roses can also be propagated by seeds, cuttings, or grafting, 'T' budding is the most commonly used commercial method for ensuring high-quality, uniform plants.
