Germination experiment! 10 year old seeds. Half were soaked in 3% food grade Hydrogen Peroxide for 1 hour, and the other half were not treated. Seeds were then placed between wet paper towels on a seedling heat mat.
After 3 days, 9/11 untreated seeds had significant roots, but only 6/11 of the Hydrogen Peroxide treated seeds had significant roots. Both sides also had a seed that'd only cracked. So the untreated seeds did significantly better!
This was a surprise for me because in a previous test, seeds treated this way with Hydrogen Peroxide seemed to do better 🤷♀️ I may try another test and dilute the H2O2, perhaps soaking seeds for longer. Another thought is to add a little H2O2 to the water I use to wet the paper towels instead of soaking seeds.
I tried to crack some seeds to test that as a way to increase germination rates, but that was a disaster ☠ Let's just say that I crushed tons of seeds until I found a technique that worked. I'm not sure I'd recommend cracking seeds to the uninitiated. I decided to do a test with just Hydrogen Peroxide vs untreated and that's how this experiment came to be.
Anyone else use Hydrogen Peroxide to try to increase seedling germination rates? How did it go for you? - 4 hours ago
