Question

In grafting, the stem part is attached to the soil is called

Answer 1

Hint: Grafting is a method of artificial vegetative propagation. In this two or more parts of the plant are joined so that they appear to grow as a single plant. It is a labour intensive method but is commonly done as a means of vegetative propagation.

Complete answer:
Grafting is a technique used in asexual reproduction of plants grown commercially. In this the tissues of plants are joined together so that they continue to grow together.
The grafting plant has two parts.
The upper part of the combined plant is called the scion and the lower part is called the rootstock. The successful grafting is dependent on the vascular tissues that grow together. This is called inosculation. The plant with desired root is selected as rootstock and the other plant of desired tem, leaves, flowers and fruits forms the scion. The desired gene that is duplicated belongs to that of scion.

Advantages of grafting-
1.The fruiting of the grafting plants begins in less than two years.
2.It helps in producing dwarf plants which are commercially more important.
3.Grafting reduces the time of flowering.
4.It provides strong and tall trunks for ornamental plants.
5.This technique is useful in repairing the damaged trunk.

Hence, the correct answer is scion

Note: The plants which lack vascular cambium cannot be joined by the method of grafting. The genetically closer plants form successful grafts. When the grafting is performed in between the different genera of the same family then the chances of successful graft is very low. The chances of grafting between different families are very less, almost rare.
