Q). How many types of artificial asexual reproduction found in plant? Which type of plant showing grafting?

Dear studet.

Vegetative propagation is a mode of asexual reproduction in plants where the vegetative parts such as roots, leaves, stems, etc. are used to propagate the plants. The artificial methods of vegetative propagation is very common practice to vegetatively propagate plants that have desirable characteristics. It includes- cutting, layering, grafting ,tissue culture etc.

Cutting: Here the cuttings of the "parent" plant are removed and placed in a suitable environment so that they can grow into a whole new plant. For example rose cutting.

Layering: The stem is bent down and the target region buried in the soil. The buried part of stem develops roots and is detached from the plant and develops into new plant.

Grafting refers to the process of artificial vegetative propagation in plants in which a stem cutting from the desired plant (scion) is inserted in a rooted plant (stock), which is resistant to diseases. Then, they are bound firmly with tape or cloth so that they have vascular continuity. Examples include rose, mango and citrus.  

Plant tissue culture: Tissue culture is the artificial method of reproduction where a small cutting of plant such as root or stem is taken and is grown in laboratory condition by providing it with suitable nutrients in a media and growing them in a petri plate or test tubes. The plant is provided with the most hygienic condition.
