The Orchestrators of Growth

Just like humans, plants are governed by hormones. In the world of agro-chemicals, we focus on three primary groups that determine how a plant grows, flowers, and fruits.

1. Auxins (The Architects)

Auxins (like Indole Acetic Acid - IAA) are responsible for root development and apical dominance (upward growth). They tell the plant where to send its energy first. Used extensively in rooting powders and for preventing fruit drop.

2. Gibberellins (The Energizers)

As discussed in our GA3 Guide, Gibberellins stimulate cell elongation and break seed dormancy. They are the key to larger fruit clusters and taller stems.

3. Cytokinins (The Youth Hormones)

Cytokinins (like 6-BA) promote cell division and delay the aging of leaves. They are essential for branching (lateral growth) and keeping produce fresh after harvest.

Finding the Balance

Success in horticulture often comes down to the ratio of these hormones. High Auxin/Low Cytokinin ratios promote rooting, while High Cytokinin/Low Auxin ratios promote budding and branching.

Conclusion

Understanding these biological triggers allows you to "talk" to your plants and direct their growth. Classic Organic Chemicals provides high-purity technical grades of all three hormone groups for professional use.
