Could you be more specific about the species that do not respond to your
treatment. I am awaiting a batch of seeds from Lowrie and have planned
to experiment with gibberellic acid (1 mg/ml). Do you (or any) know if
the concentration of GA affects the survival of the seedlings. I applied
GA (unknown concentration) to seeds of _U. calycifida_. Both control and
treated seeds germinated (70-80% success), with the germination of the
control seeds a week delayed. Unfortunately the "treated" seedlings died
within a week. Just a coincidence - or are there similar observations?
