Anyone use this for chemical scarification/germination assistance? KNO3 can be purchased as Stump Remover

I have used it on occasion and now have an experiment with Canna seeds

Control - soak overnight in H2O2/water solution
Test 1 - scarified on sandpaper and soak overnight in H2O2/water solution
Test 2 - chemical scarification in Potassium Nitrate
Test 3 - Boiling water over seed.

Control & Tests 1 & 2 are working overnight. I will do the boiling water tomorrow and plant tomorrow night.

Your thoughts or experiments?

I had heard of this , but did not know that it was stump remover.

Last year I did Canna as a Wintersow, and several did germinate.

Canna germinates for me if it is just nicked, and placed in warmth under lights.

My germination experiments are on Peony seeds this year using GA3 or IAA or IBA?.

So far no results on peonies.

Trying GA3 on Rosemary seeds and Parsley seeds.

We will all be interested in your results, David.

There are two variables (different from your control) to account for in your potassium nitrate lot: 1) not soaking and 2) the addition of potassium nitrate. How will you know which is responsible for the outcome?

There is some very good info out there on GA3. I have some, but must admit, I have not tried it a lot.

What is IAA?

Not following you. Are you suggesting I should also have a test or Control of doing nothing and just planting the seeds?

If so - I have no interest in that. I know the results - FOREVER. I chose not to test that.

Another test I could have done was scarify (via sandpaper) and then soak in Potassium Nitrate.

Another test would be using GA3.

And another test .....
And another ....

If these all grow, I am going to have a lot of Cannas already.

IAA is Indole Acetic Acid.
Should have said IBA ? Indole Butyric Acid?
IBA is the chemical component in the "Roots" gel.
The gel also has a fungicide in it.
When I was researching seeds from the NARGS swap,--
I came across info that IAA was used to shorten the warm ? or cold? period for some seeds.
So I thought I would try IBA on peony seeds.
So far there are no results to report.

But I do have a control which only had peroxide water as pretreatment.
I treat all peony seed with peroxide water first.
But one bag has had no further chemical treatment.

Yes, that is exactly what I was saying.
But now, since you say already know the results of one of the variables, that is how you will know! (So you have answered my question.)

Sorry if I confused anyone over IAA and IBA.
It is the Wilsons Root Gel that I am using which is IBA .
I dissolved a 50 ml bottle,
and made it up to approximately one liter in a shampoo bottle.

I think the IAA is the chemical component of that spray for tomato blossoms.

Both IAA and IBA have been used to treat seeds. They are very similar.

Right. I guess.

I have grown Canna with NO treatment (not even soaking in plain water) and it takes forEVERRRRRRR. So I chose not to do that at all.

My "base" or control is simply H2O2 which is what many folks use

I use one of the best products that is basically IBA - DipnGrow. But I only use it for rooting/propagating cuttings. I dip cuttings for like 3 - 7 seconds. I have never seen a product that can be used on seed.

That Wilsons stuff is recommended for seeds? How long do you soak them? I am unfamiliar with it.

Hmmmm Google search. You got some whacky weed going? That product looks like it is made for dipping cuttings.

No it is not recommended for seed.
It is for dipping cuttings.
I just thought I would try it on seeds.

Keep us posted. Maybe you are on to something.

Maybe?

I went ahead and scarified Test 3 - Boiling water over seed.

The two that I scarified were showing little white growth at scarification point, so I know which will come up first.

Planted all my test Canna seeds today. 24
