Germinating Nitraria schoberi

Posted by Raymondo Armidale, NSW (My Page) on

I have some seeds for Nitraria schoberi, Nitre Bush, and have heard that the folloxing are useful, perhaps even necessary, for successful germination.

Fermenting seeds in damp soil in a plastic bag for some period.

Soaking in hydrogen peroxide (bleach) for some time.

Scarification or even removal of outer casing.

Sulphuric acid treatment (not suitable for me).

Does anyone have any experience with this plant? If so, what method(s) did you use? For the H2O2 treatment, what concentration is necessary and over what time period? For the fermenting, what period is best?

Hoping there's someone out there who can answer this.

RE: Germinating Nitraria schoberi

I think you are supposed to feed it to an Emu. I don't know if chickens or geese will work.

The peroxide treatment is probably just to sterilise the seed coat to reduce fungal attack - it is a good idea with any temperamental species. And peroxide is not household bleach, bleach is usually Sodium hypochloride. I believe that household disinfectant is softer than either peroxide or hypochloride, but I haven't tried it.

My theory about the boiling water trick for peas is that it also sterlises the seed coat, and in my experience I get the same germination by using a chemical steriliser (I usually use metho for hard coat peas as it is almost instant) as I do with boiling water. Soaking the peas over night is useful.

If you want to try an acid treatment, try using cleaning vinegar (much more concentrated than drinking vinegar). You can measure the phd using a soil phd kit.

I have never germinated nitre bush.
