Item Histopathology of ginger (Zingiber officinale) infected by soil nematode Meloidogyne sp.(1977) Jaisukh J. Shah; Chacko Raju, E.Histopathology of ginger (Zingiber officinale Rosc.) infected by soil nematode Meloidogyne sp. has been investigated. Except the aerial shoot system all the other parts of the plants, the roots, rhizomes and scale leaves are infected by the nematodes. The initial target of infection is near the xylem pole. Hyperplasia of parenchyma cells is common in the infected rhizomes and roots. However, galling is conspicuous in adventitious roots. The infection induces the formation of giant cells and the active division of cells surrounding the infected area. The giant cell show akaryotic division of nuclei and thickened cell walls which may show fine irregular wall projections.
