Which of the following is used for bolting in beet?

Options

A. Kinetin
B. Xylene
C. Ethylene
D. gibberellin

Answer

To solve the question "Which of the following is used for bolting in beet?", we will analyze the provided options step by step.

### Step 1: Understand the concept of bolting
Bolting is the process where a plant rapidly elongates its stem and produces flowers, typically in response to environmental cues such as temperature and light. This is particularly important in plants like beet, which are cultivated for their edible parts.

### Step 2: Analyze the options
We have four options to consider: Kinetin, Xylene, Ethylene, and Gibberellin.

### Step 3: Evaluate Kinetin
- Kinetin is a type of plant hormone known for promoting cell division.
- It does not specifically promote bolting in plants.
- **Conclusion**: Kinetin is not the correct answer.

### Step 4: Evaluate Xylene
- Xylene is a chemical compound, not a plant hormone.
- It is used primarily as a solvent in various industries, such as printing and rubber manufacturing.
- **Conclusion**: Xylene is not the correct answer.

### Step 5: Evaluate Ethylene
- Ethylene is a plant hormone that plays a significant role in the ripening of fruits and regulating growth and senescence.
- While it is important for various growth processes, it is not specifically known for inducing bolting in beet.
- **Conclusion**: Ethylene is not the correct answer.

### Step 6: Evaluate Gibberellin
- Gibberellin is a plant hormone that promotes growth and is specifically known for inducing bolting in certain plants, including beet and cabbage.
- It promotes internode elongation, which is a key aspect of the bolting process.
- **Conclusion**: Gibberellin is the correct answer.

### Final Answer
The correct option for the question "Which of the following is used for bolting in beet?" is **Gibberellin**.
