Seedless tomatoes are produced by

Options

A. Supplying radioactive compounds
B. Spraying hormones on flowers
C. Propagating tomato plants from cuttings.
D. Growing tomato plants in mineral solution.

Answer

To answer the question "Seedless tomatoes are produced by," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Concept of Seedless Tomatoes**:
- Seedless tomatoes are cultivated to avoid the inconvenience of seeds in the fruit. This is particularly desirable for consumers who prefer a smoother texture in their tomatoes.

2. **Identifying the Process**:
- The production of seedless tomatoes is primarily achieved through a process known as **parthenocarpy**. This is the development of fruit without fertilization.

3. **Mechanism of Parthenocarpy**:
- In parthenocarpy, the ovules in the flower do not get fertilized. As a result, seeds do not form, leading to the development of seedless fruits.

4. **Role of Hormones**:
- The hormone **auxin** plays a crucial role in inducing parthenocarpy. When auxins are applied to the flowers of tomato plants, they stimulate the development of fruit without the need for fertilization.

5. **Evaluating the Options**:
- Given the options provided:
- **Option 1**: Supplying radioactive compounds - Incorrect.
- **Option 2**: Spraying hormones on the flowers - Correct, as it relates to the use of auxins.
- **Option 3**: Propagating tomato plants from cuttings - Incorrect.
- **Option 4**: Tomato plants in mineral solution (hydroponics) - Incorrect.

6. **Conclusion**:
- The correct answer is **Option 2: Spraying hormones on the flowers**. This method effectively induces parthenocarpy, resulting in seedless tomatoes.
