Keywords:anthurium andraeanum, burrowing nematode, histopathology, madeira, radopholus similis, rhizomes
AbstractRadopholus similis, the burrowing nematode colonizes and reproduces in roots and rhizomes of Anthurium andraeanum Linden ex Andre in Madeira, Portugal. Histological examination of nematodeinfected rhizomes shows necrosis and cavities extending from the cortical parenchyma into the vascular bundles. Nematode feeding and migration caused disruption of the vascular bundles. All nematode life stages, coiled juveniles, adults, including gravid females, and eggs, occurred in the phloem. Nematode specimens were also observed in metaxylem elements.
