Artificial induction of roots on stems before it is separated from the parent plant for propagation is called

Options

A. Cutting
B. Layering
C. Plant tissue culture
D. Grafting

Answer

To solve the question, we need to identify the process described: "artificial induction of roots on stems before it is separated from the parent plant for propagation." Let's break down the options provided:

1. **Cutting**: This is a method where a part of the plant (usually a stem or leaf) is cut and placed in a suitable environment to grow roots. However, this process typically involves separating the cutting from the parent plant before roots are induced.

2. **Layering**: This technique involves inducing roots on a stem while it is still attached to the parent plant. A section of the stem is buried in the soil, and roots develop at that point. This matches the description provided in the question.

3. **Plant Tissue Culture**: This is a laboratory technique used to grow plants in a controlled environment, usually involving small pieces of plant tissue. It does not involve the induction of roots on stems while still attached to the parent plant.

4. **Grafting**: This is a method of joining two plant parts together so that they grow as one. It does not involve the induction of roots on the stem.

Based on this analysis, the correct answer is **Layering**.

### Step-by-Step Solution:
1. **Identify the process**: The question describes a method of inducing roots on a stem while it is still attached to the parent plant.
2. **Evaluate the options**:
- **Cutting**: Involves separation before root induction.
- **Layering**: Involves root induction while still attached to the parent plant.
- **Plant Tissue Culture**: A lab technique, not applicable here.
- **Grafting**: Involves joining plant parts, not root induction.
3. **Select the correct answer**: Based on the evaluation, the process described is best matched by **Layering**.
