Select the incorrect statements among the following
(A) Many domestic plants do not germinate due to Quiescence.
(B) Seeds of Polygonum do not germinate because they contain chemical compounds which inhibit their germination.
(C) Type of dormancy caused by hard seed coats can be broken by stratification.
(D) The seed of Ranunculus does not germinate as the embryo has not reached morphological maturity.

Options

A. A and D
B. B and C
C. C and D
D. B and D

Answer

To determine the incorrect statements among the given options, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Analyze Statement (A)**:
- **Statement**: Many domestic plants do not germinate due to Quiescence.
- **Analysis**: Quiescence refers to a state where seeds are viable but do not germinate due to unfavorable environmental conditions. This statement is **correct**.

2. **Analyze Statement (B)**:
- **Statement**: Seeds of Polygonum do not germinate because they contain chemical compounds which inhibit their germination.
- **Analysis**: This statement is **incorrect**. The seeds of Polygonum do not germinate primarily due to environmental factors, such as high calcium levels in the soil, rather than chemical inhibitors.

3. **Analyze Statement (C)**:
- **Statement**: Type of dormancy caused by hard seed coats can be broken by stratification.
- **Analysis**: This statement is also **incorrect**. The dormancy caused by hard seed coats is typically broken by scarification, not stratification. Stratification is a process that involves moist chilling to break dormancy in seeds that require cold temperatures.

4. **Analyze Statement (D)**:
- **Statement**: The seed of Ranunculus does not germinate as the embryo has not reached morphological maturity.
- **Analysis**: This statement is **correct**. The seeds of Ranunculus may not germinate if the embryo is not fully developed or mature.

### Conclusion:
The incorrect statements are **(B)** and **(C)**.

### Final Answer:
The incorrect statements are (B) and (C).
