For the sake of clarity of graphs, the graphs for chisel plow, which were mostly intermediate between the other graphs, are not shown. Error bars indicate ±1 SE

(Top) Groups of pigmented cells formed on root surface in response to halting of penetration by Gaeumannomyces–Phialophora and hyphe of these fungi on the root surface. (Bottom) Resting spores of Olpidium and cystosori of Polymyxa inside the root cells
