Effects of Perennial Peanut (Arachis glabrata) Ground Cover on Nematode Communities in Citrus

The effects of perennial peanut (Arachis glabrata) ground cover on the nematode community in a citrus orchard were examined. Samples were taken from two different ground cover treatments (perennial peanut or bare ground) at each of three distances from the tree trunk. Richness, measured as total num...

520 |a The effects of perennial peanut (Arachis glabrata) ground cover on the nematode community in a citrus orchard were examined. Samples were taken from two different ground cover treatments (perennial peanut or bare ground) at each of three distances from the tree trunk. Richness, measured as total numbers of nematode genera per sample, and total numbers of nematodes were greatest in the perennial peanut treatment (P < 0.05). Abundance of many genera of bacterivores, fungivores, and omnivores were increased by the perennial peanut ground cover. Total numbers of plant parasites were greater in perennial peanut treatments on three of the five sampling dates (P < 0.05), mainly due to trends in numbers of Mesocriconema. Distance from a tree trunk and the interaction of ground cover treatments and proximity to a tree trunk were most influential for Belonolaimus and Hoplolaimus. Although differences among treatments were observed for nematode genera and trophic groups, ecological indices were not consistently sensitive to treatments. Among several ecological indices evaluated, richness was most often affected by ground cover treatment
