As the thread of seed germination problems came across my desk, I waited for 
someone to mention the use of Gibberellic Acid.  I have very little 
experience with this plant hormone, but understand that it can be used for a 
variety of purposes depending on the concentration used.  For example, a 
reference I have indicates:

50ppm   - Early flowering
200ppm  - Early flowering
800ppm  - Blossom set
2000ppm - Seed germination
1%paste - Growth promoter

Another reference I have discusses delaying senescence of citrus with G.A.

Does anyone on the list use Gibberellic Acid on their farms?  If so, what 
have your experiences been?
