Cytological changes at the end of the severed laticifers after tapping under a light and an electron microscope. a The trunk of regularly tapped tree, showing the tapping panel. Green circle shows the site of bark sample collection. b-d Radial sections of bark at tapping panel showing the formation of protein-network within and over the laticifer wounds at 0 min (b) and 5 min (c) after tapping and as soon as the flow of latex stopped (d). The red arrow shows the end of the severed laticifers. e-f Longitudinal section of the end of the laticifer vessels under an electron microscope, showing the lutoids that changed from an intact vesicle (red arrows) with surrounding membrane to an electron-dense network (yellow arrows), the rubber particles that remained intact (blue arrows) immediately at the cessation of latex flow (e), and the coagulated rubber particles without membrane structure and the network of electron-dense materials (yellow arrows) 24 h after latex flow stopped (f). The purple arrow shows the cuts of cell wall
