The correct Answer is:
To answer the question about which plant growth regulator can induce more female flowers in cucumber plants, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Requirement**: The farmer wants to cultivate cucumber plants and is specifically interested in increasing the number of female flowers. 2. **Identify Plant Growth Regulators**: We need to evaluate the different plant growth regulators available and their effects on flower sex expression in cucumbers. 3. **Evaluate Each Option**: - **Option 1: Ethylene**: Ethylene is known to promote female sex expression in flowering plants. It increases the number of female flowers while reducing the number of male flowers. This makes it a suitable choice for the farmer's needs. - **Option 2: Abscisic Acid**: This plant growth regulator does not influence sex expression in flowers. Its primary role is in processes like leaf and fruit abscission, making it an unsuitable option for this purpose. - **Option 3: Gibberellins**: Gibberellins are known to promote male flower development and help in seed germination. Therefore, this option does not meet the farmer's requirement for increasing female flowers. - **Option 4: Cytokinins**: While cytokinins promote cell division and growth, they do not have a direct effect on the sex expression of flowers. Thus, this option is also not suitable. 4. **Conclusion**: Based on the evaluation, Ethylene is the plant growth regulator that can effectively induce more female flowers in cucumber plants. ### Final Answer: The correct plant growth regulator to suggest to the farmer for increasing the number of female flowers in cucumber plants is **Ethylene**. ---
