D. Jasmine

Answer 1

Grafting or graftage is a horticultural process by which plant tissues are combined to continue their joint growth. The upper part is known as the scion of the combined plant, while the lower part is called the rootstock. Growing together of the vascular tissues is the success of this joining, and such joining is called inoculation. The method is most commonly used in the asexual propagation of plants commercially grown for horticultural and agricultural trade.

Complete Answer:
- A shoot of a chosen, desired plant cultivar is grafted onto the stock of another type during stem grafting, a conventional grafting technique.In another common method called bud grafting on the stem of another stock plant, a dormant side bud is grafted and when it has successfully inosculated, it is encouraged to grow just above the newly grafted bud by pruning off the stem of the stock plant.
- The vascular cambium tissues of the stock and scion plants must be put in contact with each other for effective grafting to take place. It is necessary to keep both tissues intact, usually for a period of a few weeks, before the graft is removed. Efficient grafting allows only a vascular contact to take place between the tissues grafted.
- Instead of a twig, bud grafting (also called chip budding) uses a bud. The most common instance of bud grafting is grafting roses. A bud is removed from the parent plant in this process, and the base of the bud is inserted under the bark of the stock plant stem from which the rest of the shoot has been cut. Each additional bud that begins to develop from the stem of the stock plant is removed.
- Examples: Peach-like roses and fruit trees. Budwood is a stick that can be cut out and used for bud grafting, with several buds on it. For citrus trees, it is a common way of propagating.

The correct Answer is option (C) Rose.

Note: In the summer, between July and September, bud grafting, or chip budding, is done so that the bud has enough of the growing season to recover into the rootstock, but before it can expand, it reaches winter dormancy. This means that any rootstocks where spring bench grafts have failed can be chipped, giving you another stab at the success of propagation in the same year.
