Spraying juvenile conifers with GA hastens the maturity period thus leadig to early seed production.

Answer

**Step-by-Step Solution:**

1. **Understanding Gibberellic Acid (GA):**
- Gibberellic acid, commonly referred to as GA, is a plant hormone that plays a crucial role in regulating growth and development in plants. It is known to promote cell division and elongation.

2. **Role of GA in Plant Growth:**
- GA affects various aspects of plant growth, including stimulating the elongation of stems and the expansion of leaves. This hormone is particularly important during the early stages of plant development.

3. **GA and Maturity Period:**
- When juvenile conifers are treated with GA, it has been observed that the maturity period of these plants is hastened. This means that the time it takes for these plants to reach maturity and be ready for reproduction is reduced.

4. **Impact on Seed Production:**
- By hastening the maturity period, GA leads to earlier seed production in juvenile conifers. This is beneficial for forestry and agriculture as it allows for quicker harvesting of seeds.

5. **Conclusion:**
- Based on the information provided, the statement that "spraying juvenile conifers with GA hastens the maturity period thus leading to early seed production" is true.

**Final Answer: True**
