Plant Hormones Science Fair Project

The Effects of Growth Hormones

The Effects of Growth Hormones | Science Fair Projects | STEM Projects
Radiation can be damaging to plants, but what if we could help them recover? Let's find out if growth hormones can help plants that have been exposed to radiation.


The hypothesis is that growth hormone supplementation will help irradiated lima beans recover from radiation damage.

Method & Materials

You will irradiate lima beans with high-energy X-rays, then place them in a hydroponic germination station and expose them to artificial light. Half of the beans will be given growth hormone supplementation and the other half will be hydrated with clean water only.
You will need 48 lima beans, high-energy X-rays, a hydroponic germination station, artificial light, and Hormex Growth Hormone.


The results showed that growth hormone supplementation did not repair stem length damage in the irradiated plants, but it did slightly increase root length. This suggests that the growth hormone may be able to make up for the damage inflicted by the radiation.

Why do this project?

This science project is interesting because it explores the potential of growth hormones to help plants recover from radiation damage.

Also Consider

Experiment variations to consider include using different types of radiation, different types of growth hormones, and different types of plants.
