In the process of vegetative propagation, which part of the plant is used in grafting?
Stem
Leaf
Seed
Root
Stem
Grafting is a horticultural technique where tissues from one plant (the scion) are inserted into those of another (the stock) so that they grow together as a single plant. This process is a common form of vegetative propagation that requires the use of a healthy, stem-based section from the parent plant to ensure genetic consistency and desired characteristics in the offspring.

This process is a common form of vegetative propagation that requires the use of a healthy, stem-based section from the parent plant to ensure genetic consistency and desired characteristics in the offspring.
Vegetative propagation is a form of asexual reproduction in plants, distinct from sexual reproduction via seeds, and is extensively used in the study of Plant Biotechnology and Agriculture under the National Horticulture Mission (NHM).
Grafting involves uniting a scion (part to be propagated) with a rootstock.
Only stem tissues are capable of vascular cambium union required for successful grafting.
This method is widely used for fruit trees like mango, apple, and citrus to maintain superior quality.
Scion: The upper portion of the graft that determines the fruit/flower variety.
Stock (Rootstock): The lower portion that provides the root system.
Option B (Leaf): Leaves are rarely used for propagation in grafting (though used in leaf-cutting propagation).
Option C (Seed): Seed-based propagation is a sexual process, not vegetative.
A is correct тАФ Grafting is a vegetative propagation technique specifically requiring stem segments (scion) to be fused with a rootstock.
Link this to 'Botany' chapters on plant tissues; grafting success depends entirely on the 'Vascular Cambium', which allows xylem and phloem continuity between the two stems.
