Plants with poor root system are propagated through

Options

A. A. Layering
B. B. Leaf cuttings
C. C. Stem cuttings
D. D. Grafting

Answer

**Step-by-Step Solution:**

1. **Understanding the Question:**
- The question asks about the propagation method suitable for plants with a poor root system.

2. **Analyzing the Options:**
- **Option A: Layering**
- Involves placing a part of the plant in the soil to encourage root development.
- **Option B: Leaf Cuttings**
- Involves embedding leaves in the soil to grow roots.
- **Option C: Stem Cuttings**
- Involves cutting a stem and placing it in the soil to develop roots.
- **Option D: Grafting**
- Involves joining two different plants together, where one (rootstock) has a strong root system.

3. **Evaluating Each Method:**
- **Layering, Leaf Cuttings, and Stem Cuttings:**
- All these methods require the plant to develop roots from the cut parts. Since the plants in question have a poor root system, they may not be able to successfully develop roots through these methods.
- **Grafting:**
- This method uses a rootstock with a strong root system, which can support the scion (the part of the plant that is grafted on). This allows the scion to benefit from the strong roots of the rootstock, making it a suitable method for plants with poor root systems.

4. **Conclusion:**
- The most appropriate method for propagating plants with a poor root system is **Grafting** (Option D).

**Final Answer:**
Plants with poor root systems are propagated through **Grafting** (Option D).
