Abstract

Distribution of nematodes associated with saplings in Korea.

Abstract

Soil samples collected from the root area of 119 sapling tree or shrub species (growing at eight Forestry Experiment Stations in Korea Republic) were surveyed for associated nematodes. Thirty-five nematode species (20 genera, 11 families, 2 orders) were identified. Xiphinema insigne was previously unrecorded in Korea Republic; Geocenamus sp. a new species. The highest detection rate (DR) at all stations except one (Nambu) was for Tylenchorhynchus claytoni, which was the dominant species among those associated with saplings. The DR of T. claytoni varied from 100% (15 trees at Chungnam), to 40% (Cheonnam). Other important nematode species which exhibited high densities at some stations were Criconemella morgensis (DR 37.5%), Helicotylenchus digonicus (DR 35%), Pararotylenchus pini (DR 37%), T. nudus (DR 37.9%), C. informis (DR 27.5%), and Meloidogyne sp. (DR 12.5%).
