Protocol

DerivedN. C. Deno, 1993

Difficulty Low Rated by us, not by the source.

  1. Warm moist stratification

    Temperature: 70°F 21°C

    70%, over 3-9 days.

  2. Cold moist stratification

    Duration: 90 daysTemperature: 40°F 4°C

    Deno gives no length for this period; three months is his standard cycle.

  3. Warm moist stratification

    Temperature: 70°F 21°C

    A further 10%.

  4. Cold moist stratification

    Duration: 90 daysTemperature: 40°F 4°C

    Deno gives no length for this period; three months is his standard cycle.

  5. Warm moist stratification

    Temperature: 70°F 21°C

    A further 3%.

Steps after step 1 run on after germination.

No stated waiting before sowing. Then 9 days to germinate.

70% germination in 3–9 days.

70% in the first nine days at 70. Two further cycles add 10% and 3% -- worth running for the remainder, but this is a warm germinator.

This source doesn't state how long.
