Individualistic effect of gibberellins is

Options

A. apical dominance
B. bolting
C. dormancy
D. fruit ripening

Answer

### Step-by-Step Solution:

1. **Understanding Gibberellins**: Gibberellins are a class of plant hormones that play a crucial role in promoting growth and development in plants. They are known for their effects on various physiological processes.

2. **Identifying Individualistic Effects**: The question asks for the individualistic effects of gibberellins. This means we need to identify which effects are specifically and uniquely attributed to gibberellins, as opposed to other plant hormones.

3. **Key Functions of Gibberellins**:
- **Bolting**: Gibberellins are known to promote bolting, which is the elongation of the stem (internode) just before flowering. This is particularly evident in plants like cabbage and beet.
- **Seed Germination**: Gibberellins also play a significant role in breaking seed dormancy and promoting germination.
- **Internodal Elongation**: One of the primary effects of gibberellins is the increase in internodal length, which contributes to the overall height of the plant.

4. **Distinguishing from Other Hormones**:
- **Apical Dominance**: This phenomenon, where the growth of lateral buds is inhibited by the apical bud, is primarily regulated by auxins, not gibberellins.
- **Dormancy**: The dormancy of seeds is regulated by abscisic acid (ABA), which is also not a function of gibberellins.
- **Fruit Ripening**: Ethylene is the hormone primarily responsible for fruit ripening, again not related to gibberellins.

5. **Conclusion**: Based on the above analysis, the individualistic effects of gibberellins include bolting and seed germination, while apical dominance, dormancy, and fruit ripening are regulated by other hormones.

### Final Answer:
The individualistic effects of gibberellins include bolting and seed germination.
