Which one of the plant growth regulators would you use if you are asked to
Induce growth in auxillary buds.

Answer

To solve the question of which plant growth regulator to use for inducing growth in axillary buds, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Plant Growth Regulators**: Familiarize yourself with the five main types of plant growth regulators: ethylene, gibberellins, cytokinins, abscisic acid, and auxins. Each of these hormones has specific roles in plant growth and development.

2. **Identify the Role of Cytokinins**: Recognize that cytokinins are known for promoting cell division and growth in various parts of the plant, including shoots and fruits. They play a crucial role in regulating growth processes.

3. **Focus on Axillary Buds**: Understand that axillary buds are the buds located in the axil of leaves, and their growth can be influenced by plant hormones.

4. **Link Cytokinins to Axillary Bud Growth**: Recall that cytokinins specifically promote the growth of axillary buds and help in overcoming apical dominance, which is the phenomenon where the main stem grows more strongly than the side shoots.

5. **Conclude with the Correct Answer**: Based on the information gathered, conclude that the plant growth regulator that should be used to induce growth in axillary buds is **cytokinins**.

### Final Answer:
The plant growth regulator that induces growth in axillary buds is **cytokinins**.
