Experiment: Use of Hydrogen Peroxide to induce root formation in plant cuttings

I decided to try an experiment to see if dilute concentrations of hydrogen peroxide could promote root formation in cuttings. A rack of twenty test tubes was set up in the first distilled water the second a 1/100 solution of 3% h2o2 third 1/50 solution of 3% h2o2 fourth 1/25 solution of 3% h2o2 and fifth 1/12.5 solution of 3%h2o2 We see in this image taken after one week that only the control has started growing roots. Conclusion, H2O2 does not induce rooting of cuttings.

I've got to ask - what made you think that peroxide would stimulate root-growth?
Tool Using Animal (author)  Kiteman8 years ago
Since dissolved oxygen content is important is aeroponics/hydroponics. I thought that the release of oxygen as the H2O2 decomposed would increase total dissolved oxygen. In addition that it might inhibit bacterial growth. And I was bored. ;-)
Even though you concluded that the H2O2 solutions were not a root stimulant perhaps another interesting test would be to find out whether plants (with roots) grow at a quicker rate


Btw: Asprin DOES stimulate root growth
Er, plants don't take in oxygen through the roots...

Oh, you're not the only one to try peroxide though (Link)

Yes, they do. That's why you can "drown" a plant with over watering.
Oh! Live and learn, eh?

Better than the three alternatives. ;-)
. Due to its' *cidal properties, it might help limit fungal growth during accelerated germination. Once germinated, *cidal properties probably outweigh any extra DO. . Nice experiment. I'd be interested in seeing what even lower concentrations will do. There may be a point where it will be beneficial.

Thank you, I'll give it a try.
