Quantitation of morphine and other major alkaloids in opium gum from specially cultivated Papaver setigerum DC (“Wild Poppy”) is presented. Papaver setigerum plants (n = 14) were grown in an atmosphere containing a slightly elevated level of carbon dioxide (390 ppm). Opium gum collected from the capsules of the mature plants was analyzed for morphine, codeine, thebaine, noscapine, and papaverin...

previous studies have shown that the extract of papaver rhoeas reduces morphine dependence, locomotor activity and reward. in present study, the effects of hydro-alcohol extract of papaver rhoeas on the tolerance to analgesic effects of morphine in mice have been investigated using tail flick method. subcutaneous (s.c.) administration of morphine (1, 2, 5 and 10 mg/kg) induced analgesia. howeve...

Self-fertilization, which results in reduced fitness of offspring, is a common problem in hermaphrodite angiosperms. To prevent this, many plants utilize self-incompatibility (SI), which is determined by the multi-allelic S locus, that allows discrimination between self (incompatible) and non-self (compatible) pollen by the pistil. In poppy (Papaver rhoeas), the pistil S-determinant (PrsS) is a...

31 Plant species differ in their ability to transform available recourses to biomass and to respond 32 in a plastic way to environmental circumstances; we hypothesized that such differences 33 among four weed taxa of Papaver would explain differences in their competitive response. 34 We first compared two populations each of Papaver rhoeas L., P. dubium L. ssp. dubium, P. 35 dubium L. ssp. leco...
