This source reports two treatments. Both are shown.

Protocol 1

DerivedN. C. Deno, 1993

Difficulty Very high Rated by us, not by the source.

Start around January 5, 2027 for a May 3 last frost.

  1. Cold moist stratification

    Temperature: 40°F 4°C

Germination happens during step 1, in 90 days.

6% germination in 90 days.

Trollius (Ranunculaceae). Nikolaeva (ref. 10) reported that several species had germination stimulated by GA-3. Robert and Brigitte Stewart and myself have confirmed these results with several species. However, the seedlings decline in vigor after producing a true leaf or two so that at present GA-3 cannot be recommended for the production of Trollius plants. T. chinensis:germ. 40(6% in 3rd m) and none at 70.

Protocol 2

DerivedN. C. Deno, 1993

  1. Sow and cover

    Temperature: 70°F 21°C

No stated waiting before sowing.

0% germination.

Nothing germinated at 70.
