Select the correct statements regarding parthenocarpy.

Options

A. Formation of fruits without fertilisation
B. Development of seedless fruits as in banane, graphs, nevel organge, etc.
C. Auxins and gibberellins are used to induce parthenocarpy in different plants.
D. All of these

Answer

### Step-by-Step Solution:

1. **Understanding Parthenocarpy**:
- Parthenocarpy refers to the development of fruits without fertilization. This results in fruits that are either seedless or contain non-viable seeds.

2. **Types of Parthenocarpy**:
- There are two main types of parthenocarpy:
- **Natural Parthenocarpy**: This occurs without any special treatment. Seedless fruits are produced directly from the ovaries in the absence of pollination and fertilization.
- **Induced Parthenocarpy**: This involves the production of seedless fruits through external treatments. For example, flowers can be sprayed with water extracts of pollen grains or growth-promoting hormones (like gibberellins or auxins).

3. **Examples of Parthenocarpy**:
- **Natural Parthenocarpy**: Examples include bananas, grapes, and pineapples.
- **Induced Parthenocarpy**: Examples include tomatoes and apples.

4. **Evaluating Statements**:
- The statements regarding parthenocarpy can be evaluated as follows:
- **Statement 1**: Formation of fruits without fertilization - **Correct**.
- **Statement 2**: Development of seedless fruits such as banana, grapes, and orange - **Correct**.
- **Statement 3**: Auxins and gibberellins are used to induce parthenocarpy in different plants - **Correct**.

5. **Conclusion**:
- Since all the statements are correct, the answer is that all of these statements regarding parthenocarpy are correct.
