Parthenocarpy in tomatoes can be achieved by:

Options

A. Cytokinin
B. Auxins
C. ABA
D. Zeatin

Answer

**Step-by-Step Solution:**

1. **Understanding Parthenocarpy**: Parthenocarpy is the process of fruit development without fertilization. This means that fruits can develop and mature without the need for seeds.

2. **Identifying the Role of Hormones**: To achieve parthenocarpy in tomatoes, specific plant hormones can be utilized. We need to analyze the given options to determine which hormone is effective for inducing parthenocarpy.

3. **Evaluating the Options**:
- **Cytokinin**: This hormone is involved in cell division and growth but does not directly induce parthenocarpy.
- **Oxygen**: While oxygen is essential for various metabolic processes, it is not a hormone and does not induce parthenocarpy.
- **Abscisic Acid**: This hormone primarily acts as a growth inhibitor and is involved in processes like stomatal closure and dormancy, making it unsuitable for inducing parthenocarpy.
- **Zeatin**: This is a type of cytokinin that also stimulates cell division, similar to cytokinin, and does not directly induce parthenocarpy.

4. **Identifying the Correct Answer**: Among the options provided, the one that directly relates to the induction of parthenocarpy in tomatoes is not explicitly mentioned in the options. However, the video transcript indicates that the second option, which is related to the production of parthenol (a compound associated with parthenocarpy), is the most relevant.

5. **Conclusion**: The correct answer for achieving parthenocarpy in tomatoes is through the use of hormones that promote the process, and the most suitable option from the given choices is related to the production of parthenol.

**Final Answer**: Parthenocarpy in tomatoes can be achieved by the hormone that promotes the production of parthenol.
