Plant Self-Healing 🌱 — The Role of Heteroauxin (Auxins in Plant Growth & Regeneration) | UKHTA 420

Did you know that plants, just like humans, have their own natural self-healing system?

🩹 When we get a cut, our body uses mobile blood cells to quickly move to the wound and start repairing it. But in plants, cells are fixed within rigid tissues — so how do they heal injuries?The Discovery of Auxin

👨🏼‍🔬 Back in the 1920s, scientists discovered auxins — plant growth hormones. Researchers learned that plants rely on auxin accumulation and pressure changes to recover from injuries. When a plant is wounded, auxin gathers around the damaged area. Along with a key signaling protein, it tells the plant how to respond:Some cells divide to close the wound.

Other cells stretch and elongate to rebuild tissue.

This natural mechanism allows plants to regenerate and survive even after physical damage.

Heteroauxin — The Most Common Auxin in GardeningThe most widely used auxin in horticulture is Heteroauxin (Indole-3-acetic acid, IAA). Gardeners and growers apply it because auxins play a crucial role in:

✅ Proper cell division and cell elongation

✅ Boosting plant growth and biomass

✅ Increasing crop yields

✅ Controlling apical dominance (main stem growth vs. side branches)

✅ Regulating geotropism (root growth downward into the soil)The Right Balance MattersAuxins are powerful — but concentration is everything.

⚠️ Low levels → lead to poor growth and tissue death.

⚠️ Excessive levels → cause uncontrolled cell division, which looks like tumor-like growths near the wound.

That’s why gardeners must use moderate doses of Heteroauxin: it supports regeneration, promotes healthier and stronger plants, and helps your cannabis or garden crops grow larger and more resilient.

🌿✨ConclusionAuxins are nature’s way of letting plants heal, adapt, and thrive. Using Heteroauxin properly can:Improve your yieldsStrengthen plant tissuesSupport root and shoot growthEnsure faster recovery after pruning or damage

👉 Remember: balance is key. With the right application, Heteroauxin will maximize your plant’s potential without causing harm.
