Nematodes associated with forest trees in Korea. I. Studies on nematodes associated with saplings.

Abstract

The results of a survey on the nematodes associated with saplings from 8 Forestry Experiment Stations in Korea are reported herein. A total of 35 species under 20 genera, 11 families, and 2 orders were identified from the soils around the roots of 119 tree species and amongst them, Xiphinema insigne is a new geographic record for Korea and Geocenamus sp. is a new species. Tylenchorhynchus claytoni, which showed the highest detection rate, in all areas except Nambu, was the dominant species among the nematodes associated with saplings. Other important nematode species which showed very high densities were: Criconemella morgensis, Helicotylenchus digonicus, Pararotylenchus pini, Tylenchorhynchus nudus, Criconemella informis, and Meloidogyne sp.
