Fig. 8From: Ethephon induced oxidative stress in the olive leaf abscission zone enables development of a selective abscission compoundEffect of ethephon treatment on ROS formation in the leaf and fruit AZs before (a) and 3Â days after (b) treatment. DCF fluorescence under a confocal scanning microscope of the LAZ and FAZ2 is presented. The location of the AZs is indicated by yellow arrows. P, proximal side; D, distal sideBack to article page
