Germination rates of four Chilean forest trees seeds: Quillaja saponaria, Prosopis chilensis, Vachellia caven, and Caesalpinia spinosa

Comparative Serology of a Disjunct Species Group: The Prosopis juliflora-Prosopis chilensis Complex

Actual and potential applications of Yuccaschidigera and Quillaja saponaria saponins inhuman and animal nutrition

Saponins are natural detergents (surfactants) found in a variety of plants. The two major commercial sources are desert plants: Yucca schidigera from Mexico and Quillaja saponaria from Chile. Yucca saponins have a steroid nucleus, whereas Quillaja saponins are triterpenoid in structure. Saponins contain a lipophilic nucleus (steroid or triterpenoid) and one or more water– soluble carbohydrate s...

Salinity effects on germination and growth

Prosopis chilensis, also named Chilean algarrobo, is a leguminous tree, described as highly tolerant to heat shock, water deficit, salinity and injury stress. The objective of this research was to investigate the germination and growth responses of seeds, seedlings and young plants of P. chilensis under increasing concentrations of N a Cl. Six groups of P. chilensis seeds were germinated. One g...

Isolation and characterization of 12 microsatellite loci in soapbark, Quillaja saponaria (Quillajaceae)1

Ap Applicati tions ons in in Pl Plant t Scien Sciences ces Quillaja saponaria Molina is an endemic Chilean tree, known as soapbark, soap bark tree, or quillay (as it is known in Chile). It is an evergreen tree of the family Quillajaceae (Kubitzki, 2007), found from the Coquimbo Region to Arauco Province in the Bío-Bío Region, approximately between 31 ° and 38 ° south (García and Ormazabal, 2008...

Feeding saponin-containing Yucca schidigera and Quillaja saponaria to decrease enteric methane production in dairy cows.

An experiment was conducted in vitro to determine whether the addition of saponin-containing Yucca schidigera or Quillaja saponaria reduces methane production without impairing ruminal fermentation or fiber digestion. A slightly lower dose of saponin was then fed to lactating dairy cows to evaluate effects on ruminal fermentation, methane production, total-tract nutrient digestibility, and milk...
