Bolting is associated with physiological function of

Options

A. Gibberelic acid
B. Cytokinins
C. IAA
D. ABA

Answer

**Step-by-Step Solution:**

1. **Understanding Bolting:**
- Bolting is a physiological process in plants characterized by the rapid elongation of the flowering stem before the crop is harvested. This process is crucial for increasing reproductive success.

2. **Identifying the Role of Plant Hormones:**
- Various plant hormones regulate growth and development in plants. The question asks which hormone is specifically associated with the process of bolting.

3. **Evaluating the Options:**
- The options provided are gibberellic acid, cytokinins, IAA (indole acetic acid), and ABA (abscisic acid). We need to determine which of these hormones is linked to the bolting process.

4. **Linking Gibberellic Acid to Bolting:**
- Gibberellic acid is known to promote stem elongation and is often applied artificially to induce bolting in certain crops. This hormone facilitates the elongation of internodes, leading to the characteristic growth associated with bolting.

5. **Excluding Other Hormones:**
- Cytokinins, IAA, and ABA do not play a significant role in the bolting process. Cytokinins are primarily involved in cell division, IAA is related to cell elongation and differentiation, and ABA is involved in stress responses and inhibiting growth.

6. **Conclusion:**
- Based on the understanding that gibberellic acid induces stem elongation and is associated with the bolting process, we conclude that the correct answer is gibberellic acid.

**Final Answer:**
- Bolting is associated with the physiological function of **gibberellic acid**.
