Two sources report two treatments between them. Both are shown.

Protocol 1

DerivedN. C. Deno, 1996

Difficulty High Rated by us, not by the source.

Start around August 27, 2027 for a May 3 last frost. Too late for spring 2027 — that needed starting on August 26, 2026.

  1. Dry storage

    Duration: 180 daysTemperature: 70°F 21°C

  2. Gibberellic acid soak

  3. Sow and cover

    Temperature: 70°F 21°C

about 6 months from start to sowing. Then 42 days to germinate.

25% germination in 28–42 days.

Gentianella (Gentianaceae). G campestris germ. 70 GA-3(56% in 5-11 w) and 10% in April in OT Nonp germ. in 70D, 70L, 40-70D, or 40-70L. Seeds DS 1 y were dead G. turkestanorum germ. 70 GA-3 (25% in 4-6 w) and littie or none under other conditions using seeds DS 6 m. Seeds DS 2 y were dead suggesting that the 6 m DS on the seed originally received could have been detrimental

Gentianella (Gentianaceae). The splitting out of this genus and Gentianopsis from Gentiana has not been helpful as species have been shuttled around between the three genera. Light and GA-3 need to be tried. G. turkestanorum sown outdoors in January germ. well in April. A second sample germ. 70 GA-3(25% in 4-6 w) and none in 700 or 70L.
