The effect of inhibitory substances on seed germination can be removed by application of

Options

A. nitrates
B. phenolic acids
C. para-ascorbic acid
D. nitrites

Answer

To solve the question regarding the effect of inhibitory substances on seed germination, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Problem**: The question asks which application can remove the effect of inhibitory substances that prevent seed germination.

2. **Identify Inhibitory Substances**: Inhibitory substances can include various chemicals that inhibit the germination process. These may include certain acids or compounds that create dormancy in seeds.

3. **Consider Possible Solutions**: The options provided include:
- Nitrates
- Phenolic Acid
- Parascorbic Acid
- Nitrites

4. **Evaluate Each Option**:
- **Nitrates**: Nitrates are known to help in breaking seed dormancy and can promote germination by overcoming the inhibitory effects of certain substances.
- **Phenolic Acid**: This is generally associated with inhibiting germination rather than promoting it.
- **Parascorbic Acid**: There is limited evidence to suggest that this would effectively counteract inhibitory substances.
- **Nitrites**: Similar to Phenolic Acid, nitrites are not typically used to promote germination.

5. **Select the Correct Answer**: Based on the evaluation, the best option is **Nitrates**, as they can effectively remove the inhibitory effects on seed germination.

### Final Answer:
The effect of inhibitory substances on seed germination can be removed by the application of **Nitrates**.
