The image analysis showed the groundmass fabric as altered around pores owing to root activity. This alteration of the groundmass fabric concerns the lacunar porosity which was decreased by a third around the studied pores. The results showed that the latter differentiated themselves within a groundmass fabric more porous than the one currently surrounding them %G French %2 https://insu.hal.science/insu-00862447/document %2 https://insu.hal.science/insu-00862447/file/Bruand-CRAS-1992-1.pdf %L insu-00862447 %U https://insu.hal.science/insu-00862447 %~ SDE %~ INSU %~ CNRS %~ UNIV-ORLEANS %~ INRA %~ ISTO %~ OSUC %~ GIP-BE %~ AGREENIUM %~ INRAE
