Effect of pollen on character of pericarp and seed coat is

Options

A. Xenia
B. Metaxenia
C. Ruminate endosperm
D. Chimera.

Answer

To solve the question regarding the effect of pollen on the character of pericarp and seed coat, we will analyze the terms and concepts related to the effects of pollen in plant reproduction.

### Step-by-Step Solution:

1. **Understanding the Question:**
The question asks about the effect of pollen on the characteristics of the pericarp (the outer layer of the fruit) and the seed coat.

2. **Identifying Relevant Terms:**
We need to identify the terms that relate to the effects of pollen on these structures. The options provided are:
- Xenia
- Metaxenia
- Ruminant
- Chimera

3. **Analyzing Each Option:**
- **Xenia:** This refers to the influence of the pollen (male parent) on the development of the fruit characteristics. However, it primarily affects the fruit and not specifically the pericarp or seed coat.
- **Metaxenia:** This term describes the influence of pollen on the characteristics of the pericarp and seed coat, particularly through hormonal effects after fertilization. This is the correct term for our question.
- **Ruminant:** This term refers to a condition where the endosperm is dissected by the in-growths of the seed coat. It does not relate to the effect of pollen.
- **Chimera:** This term describes an organism or tissue that contains at least two different sets of DNA. It is not relevant to the question about pollen effects.

4. **Conclusion:**
Based on the analysis, the correct answer is **Metaxenia**. This term specifically refers to the effect of pollen on the pericarp and seed coat due to hormonal influences from the embryo and endosperm after fertilization.

### Final Answer:
The effect of pollen on the character of pericarp and seed coat is known as **Metaxenia**.
