These chemicals are used by government / university seed labs for maximum germination rates (which also means the fastest):
1-Naphthaleneacetic Acid (NAA)
Gibberellic Acid (GA3) 90% - Gibberellin A3
Indole Butyric Acid (IBA)
Menadione (Vitamin K3)
Polyethylene Glycol (PEG)
Sodium Hydroxide (Lye)
I think his reasoning was that alpine seeds NEED a strong dormancy mechanism since they are likely to spend a lot of time sitting on hard rocks. But when one washes into a pocket of soil, that soil is likely to have some GA3-leaking lichens. Species that have learned to use that as a signal to sprout right away have a big advantage.
IBA and NAA are auxin regulators, so they are for rooting, not germinating. I love, love, love browsing my Deno books! I've had the PDFs for ages but I finally decided to print them out and put them in a binder so that I could add my own notes. Rick, how goes your germinating so far this spring?
