Multilocus Diversity in an Outbreeding Weed, Echium piantagineum L.

Echium vulgare L

Changes in the composition of fatty acids (FA) were determined in lipid extracts isolated from developing ovaries containing ovules and developing seeds of Echium vulgare L. The samples were collected successively over 20 days beginning with the first day after flowering. The contents of the n-6 FA family members, i.e., γ-linolenic (GLA) (C18 : 3) and linoleic (LA) (C18 : 2) acids changed in a ...

Artemisia Annua L. as an Alternative Potential Weed Control Option

Stigmast-4-ene-3,6-dione an unusual phytotoxic sterone from the roots of Echium vulgare L.

Stigmast-4-ene-3,6-dione an unusual phytotoxic sterone from the roots of Echium vulgare L.

Pyrrolizidine alkaloids from Echium rauwolfii and Echium horridum (Boraginaceae).

Echimidine was isolated from Echium rauwolfii and Echium horridum and identified by MS, 1H- and 13C NMR as a major alkaloid. In addition, structures of 12 minor alkaloids were inferred from GLC and GLC-MS analyses: 7-angeloylretronecine, 7-tigloylretronecine, lycopsamine, 7-acetyllycopsamine, uplandicine, 7-angeloyllycopsamine, 7-tigloyllycopsamine, tigloyl isomer of echimidine, 7-angeloyl-9-(2...

Flowering Dynamics and Pollinator Visitation of Oilseed Echium (Echium plantagineum)

Echium (Echium plantagineum L.) is an alternative oilseed crop in summer-wet temperate regions that provides floral resources to pollinators. Its seed oil is rich in omega-3 fatty acids, such as stearidonic acid, which is desired highly by the cosmetic industry. Seeds were sown in field plots over three years in western Minnesota in spring (early-sown) or early summer (late-sown), and flower ab...
