This source reports two treatments. Both are shown.

Protocol 1

DerivedN. C. Deno, 1993

Difficulty Low Rated by us, not by the source.

Start around March 15, 2027 for a May 3 last frost.

  1. Gibberellic acid soak

  2. Sow and cover

    Temperature: 70°F 21°C

No stated waiting before sowing. Then 21 days to germinate.

67% germination in 21 days.

GA-3 is a requirement, not an improvement. The samples were small, but nothing at all germinated without it.

Aciphylla (Apiaceae). The three species studied require GA-3 for germination. With GA-3 at 70 germination was 3/3 in 3rd w for A. aurea, 2/3 in 3rd w for A. dobsonii, and 1/3 in 4th w for A. hectori. None germ. in the controls. Despite the small samples, the results are dramatic, and the seedlings were healthy.
