Re: GA-3 storage
GA-3 is giberellic acid #3 (there's lots of them) and has been shown to a
useful plant hormone, capable of initiating several different reactions in
plants. Concentrations of 1000 ppm, 500 ppm, 100 ppm, and I'm sure otehrs
have the ability to break dormancy in some species of seeds.
They can also cause aberrant growth, so it should not be used
indiscriminately. Dr. Norman C. Deno self published a seed germination
reference set which presents a good deal of data about GA-3. J L Hudson
sells GA-3, as does at least one company whose owner subscribes to this
list. JL Hudson includes a rather interesting blurb about GA-3.
The theory is that the GA-3 (and other giberellic acids) are produced by
molds in leaf litter, soil, etc. Seeds, being exposed to GA-3, assume they
are in an enviroment appropriate to their germination, and thus germinate.
Pardon the anthropomorphism, please.
This is a rather coarse treatment of the subject, I'm sure someone else can
elaborate on it. Tom Clothier's site, I believe, makes at least a passing
reference to GA-3 as well, but I've been wrong before.
