Selective seed abortion increases offspring survival in Cynoglossum officinale (Boraginaceae).
Selective embryo abortion is one of the evolutionary explanations for the surplus of ovules found in many plant species. To manipulate the level of embryo abortion, we removed ovules and applied nutrients to plants of Cynoglossum officinale (Boraginaceae) after they started to flower. From these two treatments and a control series, seeds were collected, germinated, and transplanted in the field...
متن کاملIn vitro and in vivo Production of Gingerols and Zingiberene in Ginger Plant (Zingiber officinale Roscoe)
Ginger plant, Zingiber officinale Roscoe, is an important tropical plant used as spices and well known for its medicinal properties. It has a pungent and aromatic rhizome rich of zingiberen and gingerols. Many secondary metabolites are known to accumulate in the plant cell culture systems. So, in this research, gingerols and zingiberene production of callus cultures were compared...
متن کاملPyrrole detection and the pathologic progression of Cynoglossum officinale (houndstongue) poisoning in horses.
Houndstongue (Cynoglossum officinale), a noxious weed that contains pyrrolizidine alkaloids (PAs), infests pastures and fields in the western United States and Europe. The purpose of this study was to develop techniques to better diagnose PA poisoning and describe the progression of gross and microscopic lesions caused by houndstongue intoxication. Six horses were gavaged daily with a suspensio...
متن کاملExclusion of introduced deer increases size and seed production success in an island‐endemic plant species
The presence of extra-local invaders, such as the southern California mule deer (Odocoileus hemionus) on Santa Catalina Island, may contribute to more selective and insidious effects within the unique ecosystems that have evolved in their absence. Studies at the species level may detect effects not noticed in broader, community level vegetation monitoring or help tease apart differences in the ...
متن کاملIn Vitro Regeneration Protocol for Artificial Seed Production in an Important Medicinal Plant Mentha Arvensis L
Context: The application of encapsulated shoot tips and nodal segments may contribute to the protection of rare and threatened medicinal plants. Although the artificial seed technique has been reported for more than two decades, for medicinal plants this method has not been developed sufficiently. The main limitations in conventional propagation of some species with medicinal value are: reduced...
