Quizalofop-p-ethyl (QPE) is a phenoxy herbicide which is used in agriculture to control weeds. The cytotoxic effects of QPE on pollen germination and pollen tube group in Hyacinthus orientalis were investigated and compared to the control. Experiments were carried out different QPE concentrations (0.125M and 0.25M). It was found that in vitro pollen germination and tube growth of H. orientalis was affected by QPE treatments; in particular, the highest QPE concentration caused changes in the morphological features of H. orientalis. The most potent QPE reduced pollen germination by threefold. Morphological abnormalities in the pollen tube were also observed.
