ARoseblush said:I am always learning something new here on ATP. This is the first time I have heard of 'gibberelic acid' which promotes rapid blooms(maturity) on daylily plants. I understand the reason, but have many questions as to the safety/longevity of the plants involved.
The gibberellins are a naturally occurring group of plant hormones, of which gibberellic acid is one. From what I have read, the use in seed germination is predominantly to force the seeds to break dormancy and germinate. It can be applied in other scenarios (with varying concentrations of course) that can lead to increased fruit set and blooms. Interestingly, I was reading a bit this morning, different concentrations can drive production of male or female flowers.
In the case above, I soaked the seeds for just over 40 hours in a solution that was 10% hydrogen peroxide (10% of the store bought variety so the final concentration was 0.3%) with 500 mg/mL gibberellic acid.
