Protocol

DerivedN. C. Deno, 1993

Difficulty Low Rated by us, not by the source.

  1. Warm moist stratification

    Duration: 90 daysTemperature: 70°F 21°C

  2. Cold moist stratification

    Temperature: 40°F 4°C

    Every seed, in the third week.

  3. Warm moist stratification

    Temperature: 70°F 21°C

    The single true leaf forms only now. Germination is hypogeal.

about 3 months from start to step 3. Germination happens during step 3, in 21 days.

100% germination in 21 days.

One of only two peonies that germinate at 40. A prior 3 months at 40 changed nothing.

This source doesn't state how long step 2 lasts.

Paeonea (Ranunculacèae). Nicking the seeds of P. officinalis and P. suffruticosa was reported to give some promotion to germination in the first edition, but this has not been confirmed in later and more extensive experiments. P:anomala, emodi, lutea, mlkosewetschii, obovata, and vernalis germ. at 70. similar to P.officinalis. Germination consists of forming a radicle and a branching root system. This requires about 2 m after which the seedlings are given 3 m at 40. On shifting back to 70 the true leaf forms (hypogeal). Germination was hypogeal in all but P. brownii,tand all germ. at 70 except P. broteri and P. brownii. These germ. at 40. Treatment with GA-3 gave a small increase in rate of germination in P. officinalis and P. suffruticosa. P. broteri germ. 70-40(100% in 3rd w). A prior 3m at 40 had no effect. This and P. brownii are the onlytwo Paonea that germ. at 40.
