Sexual reproduction in invasive Japanese knotweed (Reynoutria japonica) in south Sweden
Nordic Journal of Botany, EarlyView.To understand the potential for northward expansion of knotweeds into currently uninvaded regions, it is crucial to assess the potential for sexual reproduction alongside the ongoing vegetative spread. For that reason, we tested viability in Reynoutria japonica seeds in south Sweden, a region where viable seeds had not been previously reported ...

The fate of pollen in two morphologically contrasting buzz-pollinated Solanum flowers
Journal of Pollination EcologyPollen transfer efficiency (PTE) and pollen deposition patterns on a pollinator’s body significantly influence plant reproductive success. However, studies on pollen fates (i.e., the destination of pollen grains after anther dehiscence) in animal ...
