Histopathology of artichoke roots infested by Pratylenchus penetrans in Greece

  • N. Vovlas
  • F. Roca


The lesion nematode Pratylenchus penetrans (Cobb, 1917) Filipjev et Schuurmans Stekhoven, 1941 is a common pathogen of several crops in the Mediterranean area (Scognamiglio, 1963; Lamberti, 1973; Corbett, 1973; Koliopanos and Vovlas, 1977; Inserra et al., 1978). It is recorded from more than 350 plant hosts in temperate and subtropical areas but there is no information of its pathogenic association with artichoke (Cynara cardunculus v. scolymus L.). This note describes the anatomical changes induced by P. penetrans on naturally infested artichoke roots collected in heavily infested fields near Korinthos.
