Ribes. (Saxifragaceae). All seed was WC for 7 d. R. cereum was received in the red berried form and the orange berried form. Gibberelins are a natural germination requirement for this species, and the survival value of this is discussed in Chapter 12. The GA-3 treatment was varied in an effort to optimize the production of healthy seedlings. The seeds were exposed to the GA-3 for 1, 3, 5, and 8 days before removal and the GA-3 was used as described in Chapter 12 and in a dosage about 1/10 as much. The percent germinations for the normal GA-3 dosage were 90%, 29%, 61%, and 49% respectively and 30%, 35%, 42%, and 56% respectively for the 1/10 dosage. Only the lighter dosage gave healthy seedlings. The number of days of exposure did not seem to matter. The behavior of the orange berried form paralleled that of the red berried form except germination was lower. Seeds of the red berried form placed outdoors in December germ. 1% in April and an additional 2% in April a year later. Seeds of the orange berried form placed outdoors in December germ. 16% in April and an additional 25% the following April. All other treatments gave less than 1% germination over 2 y.
