Micropropagation 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 Can Overcome Seed Dormancy and Improve Seed Germination in Purple Coneflower Species Echinacea angustifolia and E. pallida
Low and erratic seed germination presents a major production problem in the medicinal plants that collectively are called echinacea or purple coneflower (Echinacea angustifolia and E. pallida). In this study, nine seed lots of each E. pallida and E. angustifolia from a wide variety of commercial sources and germplasm collections were collected and treated with a solution of 1.0 mM [144.5 mg·L-1...
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 ...
متن کاملEndophytic and rhizospheric bacterial communities isolated from the medicinal plants Echinacea purpurea and Echinacea angustifolia
In this work we analyzed the composition and structure of cultivable bacterial communities isolated from the stem/leaf and root compartments of two medicinal plants, Echinacea purpurea (L.) Moench and Echinacea angustifolia (DC.) Hell, grown in the same soil, as well as the bacterial community from their rhizospheric soils. Molecular PCR-based techniques were applied to cultivable bacteria isol...
متن کاملEchinacea species (Echinacea angustifolia (DC.) Hell., Echinacea pallida (Nutt.) Nutt.,Echinacea purpurea (L.) Moench): a review of their chemistry, pharmacology and clinical properties.
This paper reviews the chemistry, pharmacology and clinical properties of Echinacea species used medicinally. The Echinacea species Echinacea angustifolia, Echinacea pallida and Echinacea purpurea have a long history of medicinal use for a variety of conditions, particularly infections, and today echinacea products are among the best-selling herbal preparations in several developed countries. M...
