Two interesting germination research papers.

The first paper is at:

http://cat.inist.fr/?aModele=afficheN&cpsidt=18207618

Of interest in the above paper is that they found that they obtained maximum germination when they used chemical scarification and then applied GA3 to the sand that was used during stratification.

and the second is at:

(Since the second link is so long, I put it at the link below.)

The second paper reports that, red light (from LEDs)triggers GA3 and DELLA proteins to promote cotyledon expansion.

I use enzymes to degrade the seed coat and red light from LEDs during stratification. This year I will have to put GA3 in the sand during stratification.
