The mixed mating system of a widespread weed: the case of Argemone ochroleuca Sweet (Papaveraceae)

Background: Argemone ochroleuca is a worldwide invasive weed but also highly valuable for their chemical compounds. Knowledge about its reproduction will help create plans control or propagation.
 Questions: Does A. has an incompatibility system like other Papaveraceae species? Which are the reproductive strategies that favor seed formation in ?
 Studied species: annual species with bisexual flowers.
 Study site and dates: Mexico City, Mexico. The fieldwork was performed from February to May 2013, 2014, 2017.
 Methods: Direct observations were made describe flower cycle of . We used self-pollinated flowers analyze if this self-incompatible by following pollen tube growth through gynoecium. Controlled pollinations quantify compare number seeds produced per treatment know mating explore presents mechanism assurance autogamy, exhibits inbreeding depression.
 Results: self-compatible mixed system. Although outcrossing how more produced, both autogamy pseudocleistogamy present as mechanisms. Naturally pollinated produce maximum seeds, depression population. Thus, be affected continuous selfing.
 Conclusions: This study highlights mechanisms successful , common pattern weeds.
