Many new plants are obtained through

Options

A. Air layering
B. Mound layering
C. Serpentine layering
D. Both B and C.

Answer

**Step-by-Step Text Solution:**

1. **Understanding Plant Propagation Methods:**
- Plant propagation can occur through various methods, including layering, which is a technique where parts of a plant are encouraged to root while still attached to the parent plant.

2. **Explaining Air Layering:**
- Air layering involves taking a branch of a plant, making a cut, and covering it with a moist medium (like moss) and plastic to encourage roots to form. However, this method is time-consuming and not the most efficient for producing many new plants.

3. **Explaining Mound Layering:**
- Mound layering, also known as stooling, involves cutting back a woody stem and covering the base with soil. As the shoots grow, they develop roots, allowing for the formation of new plants. This method is effective for producing multiple new plants.

4. **Explaining Serpentine Layering:**
- Serpentine layering involves bending a long, flexible branch to the ground and burying sections of it while leaving some parts exposed. This technique allows multiple new plants to form at various points along the buried sections.

5. **Comparing the Methods:**
- Among the methods discussed, mound layering and serpentine layering are both efficient for producing new plants. Air layering is less effective in terms of quantity and speed.

6. **Conclusion:**
- The best options for obtaining many new plants through layering techniques are mound layering (B) and serpentine layering (C). Therefore, the correct answer is option D: both B and C.
