Figure 3 in Glufosinate enhances the activity of protoporphyrinogen oxidase inhibitors

Figure 3. Glufosinate enhances the activity of protoporphyrinogen oxidase (PPO) inhibitors, but the mixture is not effective on PPO-resistant Amaranthus tuberculatus. Response of PPO-susceptible (A) and PPO-resistant (B) A. tuberculatus to glufosinate (Gluf) and lactofen (Lact). Visual injury (C), reactive oxygen species (ROS) (D), and protoporphyrin (E) in PPO-susceptible (gray) and PPO-resistant (blue) A. tuberculatus following herbicide treatments. Asterisks (*) indicate means are significantly different by t-test (P <0.05) between biotypes within each treatment. Error bars represent the standard deviations of the means.
