Faster and better growth of pollen from other plants then the pollen from the same plant is

Options

A. Self incompatibility
B. Dichogamy
C. Monocliny
D. Prepotency.

Answer

To solve the question regarding the faster and better growth of pollen from other plants compared to pollen from the same plant, we need to analyze the provided options carefully.

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for a term that describes the phenomenon where pollen from different plants grows faster and better than pollen from the same plant.

2. **Analyzing the Options**:
- **Self-Incompatibility**: This refers to the inability of pollen grains to fertilize the flowers of the same plant or its close relatives. It promotes outcrossing but does not specifically address faster growth of pollen. Therefore, this option is incorrect.

- **Dichogamy**: This is a condition where the stigma and anther mature at different times, preventing self-fertilization. While it relates to timing, it does not imply faster growth of pollen, making this option incorrect as well.

- **Monokini**: This refers to species with functionally bisexual flowers. Although it involves mechanisms to prevent self-pollination, it does not relate to the growth rate of pollen. Thus, this option is also incorrect.

- **Prepotency**: This term describes the ability of pollen from one source (often from a different plant) to fertilize more effectively and grow faster than pollen from the same plant. This aligns perfectly with the question, making this the correct answer.

3. **Conclusion**: The correct answer to the question is **Prepotency**. This term encapsulates the concept of pollen from different plants germinating faster and being more effective in fertilization than that from the same plant.

### Final Answer:
**Prepotency**
