Is there a way to see if a Morning Glory seed has been chemically treated?

I bought 4 ounces of Morning Glory seeds and I am unsure if I bought chemically treated seeds. Is there a way to see if the seeds have been contaminated? I purchased them from www.bouncingbearbotanicals.com if anyone is familiar with their seeds.

Morning Glory seeds have to be chemically treated or they won't germinate. In the wild, they have to go through the intestines of birds or other animals before they will be able to germinate. In order to duplicate that process, it has to go through a chemical treatment.
Reply:Morning glory seeds that have been chemically treated will be coated with a powdery substance, usually pink which is an antifungal agent. If it is just dark brown or black, chances are that it is untreated.



In answer to the first responder to your question, morning glory seeds DO NOT have to be chemically treated in order to sprout. Seeds that have fallen to the ground from the previous season's vine will automatically sprout when the weather warms up. It DOES NOT need scarification - either physical or chemical by way of animal intestines in order to sprout.
Reply:As far as I know, there is no way to tell. If that site said they were organic or untreated, then that probably means they weren't treated with dyes or other chemicals. If seeds have been treated, there is no way to wash off the chemicals.
