Title

Plant parasitic nematode diversity and prevalence in traditional upland rice in Ivory Coast: preliminary observations on the effects of cropping intensification

Danny Coyne; David Hunt; R. A. Plowright; et al. Fundamental & applied nematology 1998

Other claims from this paper (8)

Observation Eighty nematode species from 35 genera were associated with rice.
Association Helicorylenchus density was significantly lower in long fallows in the forest zone.
Association Other nematode densities did not differ significantly between fallow regimes.
Observation Nematode diversity was greatest in forest-savannah, lower in savannah and least in humid forest.
Observation Nematode density and prevalence differed among agroecologies for some genera.
Observation Mewidogyne was most prevalent in forest.
Observation Pralylenchus was more prevalent in forest-savannah and savannah.
Observation Helerodera occurred at low prevalence in forest and forest-savannah.

Other claims from this paper (4)

Observation The mitochondrial changes occurred after both compatible and incompatible inoculation.
Observation Other organelles showed no morphological or ultrastructural changes.
Observation The effects occurred across epidermis, mesophyll and vascular bundle tissues of host leaves.
Intervention effect Toxin effects were not observed in non-host leaves.
