Re: [nafex] Gibberellin (GA)

I have used Ga3 to bypass stratification on nut seeds with much success. I 
carefully remove the shell first. I only used 100 to 1 dilution


The following web page talks about Gibberellin (GA) can be
used to bypass apple seed stratification.  Does anyone know
what it is?


"We concluded that Gibberellin (GA) treatment of dormant
apple embryos could be used to bypass stratification. This
practice is suggested for those who are not interested in
higher rates of germination and do not want to wait the
minimum time required for partial stratification.
Application of Cytokinins along with Gibberellin (GA)
treatment is further suggested to produce a synergistic
effect in the germination of dormant apple seeds."

The article also states that ABA (rooting hormome) will hold
a seed a seed in dormancy.  Something I never knew.

Strange that the hormone that helps stimulate roots, will
hold a seed in dormancy.
