AI Generated Solution

The correct Answer is:
To promote flowering in pineapples, the following steps can be taken: 1. **Identify the Need for Inducing Flowering**: Understand that pineapples (scientific name: Ananas comosus) can be induced to flower at any time of the year. 2. **Choose the Right Chemical**: The most commonly used chemical to stimulate flowering in pineapples is Ethiphon. This compound is preferred due to its effectiveness and safety compared to older methods. 3. **Prepare the Solution**: Ethiphon is a commercial product that needs to be mixed with water. This mixture will produce ethylene gas when applied. 4. **Understand Ethylene's Role**: Ethylene is a plant hormone that plays a crucial role in the flowering process. It is responsible for triggering the flowering mechanism in the pineapple plant. 5. **Application**: Spray the prepared Ethiphon solution on the pineapple plants. Ensure that the application is done properly to maximize the effect of the ethylene gas in inducing flowering. 6. **Consider Safety Precautions**: While Ethiphon is safer than older methods like calcium carbide, it is still important to take necessary precautions during application to avoid any adverse effects.
