Alkaloids from TurkishPapaver rhoeas
Planta Medica, 1989The major alkaloid isolated from the aerial parts of a sample of P. rhoeas proved to be (+)-rhoeadine. The minor alkaloids were allocryptopine, protopine, coulteropine, berberine, coptisine, sinactine, (+)-isocorydine, (+)-roemerine, and ...

Colour development and pigment characterisation in flowers of Papaver nudicaule and Papaver rhoeas
2021The present thesis extended the knowledge about floral pigments and volatiles and their role in plant-pollinator interaction in two widely distributed Papaver species. The bright red flowers of P. rhoeas, the corn poppy, are characterised by a highly variable colouration in the UV-A wavelength range depending on geographical distribution.

Molecular basis of resistance to sulfonylureas in Papaver rhoeas
Pesticide Biochemistry and Physiology, 2004Abstract A Papaver rhoeas population resistant to several acetolactate synthase (ALS) inhibiting herbicides, called 25/98, was found in Catalonia (Northeastern of Spain). This population has an altered form of the enzyme that showed cross-resistance to several herbicides of this group.

Behavioral and pharmaco-toxicological study of Papaver rhoeas L. in mice
Journal of Ethnopharmacology, 2001A lyophilized ethanolic aqueous extract of Papaver rhoeas petals was evaluated for its behavioral and pharmaco-toxicological effects in mice and its chemical composition was studied using thin layer chromatography (TLC). In this study, chemical analysis by TLC showed that the petals contain some anthocyanins, whereas no alkaloids were detected.

Ultrastructural Observations of Papaver rhoeas Mature Pollen Grains
Botanica Acta, 1990SummaryThe mature pollen grain of Papaver rhoeas is bicellular. The vegetative cell contains numerous mitochondria; endoplasmic reticulum is not very extensive and there are few ribosomes and plastids. Golgi bodies are in a very active state. The generative cell is lobed and spindle‐shaped. The cytoplasm contains many, generally longitudinally arranged,
