متن کاملReduction of Seed Dormancy in Echinacea pallida (Nutt.) Nutt. by In-dark Seed Selection and Breeding.
Strong seed dormancy has been an obstacle for field production of Echinacea species. Previous research on overcoming Echinacea seed dormancy has been extensive and focused on treatment methods, which involve time and expense, and are incompatible with organic production if synthetic chemicals are used. We have attempted to genetically reduce seed dormancy through selection and breeding in Echin...
متن کاملEchinacea angustifolia: An Emerging Medicinal*
The genus Echinacea (Asteraceae) is native to North America and consists of nine species (McGregor 1968). E. angustifolia DC, a narrow leafed species, is distributed on barrens and dry prairies from Minnesota to Texas, Oklahoma, Kansas, Nebraska, Iowa, the Dakotas, Colorado, Wyoming, Montana, Saskatchewan, and Manitoba (McGregor 1968; Kindscher 1989; Foster 1991). E. angustifolia grows lower an...
متن کاملMicropropagation of Echinacea angustifolia, E. pallida, and E. purpurea from Stem and Seed Explants
Micropropagation of three Echinacea species, E. angustifolia DC., E. pallida Nutt., and E. purpurea Moench., was investigated as a potential means of germplasm preservation of species faced with overcollection in the wild and rapid clonal propagation of elite individuals with unique medicinal or ornamental properties. Very high contamination rates occurred with shoot-tip explants but not with n...
متن کاملEthephon Promotes Germination of Echinacea angustifolia and E. pallida in Darkness.
Seeds from five lots each of Echinacea angustifolia DC, and E. pallida (Nutt.) Nutt. were germinated in a growth chamber in light (40 μmol·m(-2)· s(-1)) or darkness at 25 °C for 16 to 20 d after soaking in 1 mM ethephon or water for 10 min, or moist stratification at 4 - 6 °C for two weeks. Either light or ethephon promoted seed germination of E. angustifolia and E. pallida, in comparison with ...
