Plant-parasitic nematodes are not only an important constraint on agricultural crop production, but also cause both direct and indirect damage to turfgrass, which is a ground cover plant. However, studies on plant-parasitic nematodes of turfgrass in Korea are scarce. A survey for plant-parasitic nematodes was carried out on 13 golf courses in Korea. The results yielded 28 species/taxa belonging to 16 genera and 12 families of plant-parasitic nematodes. Among the isolated species, Helicotylenchus microlobus, Mesocriconema nebraskense, Tylenchorhynchus claytoni, Mesocriconema sp., and Meloidogyne graminicola were the most prevalent species in all management zones. Twelve species were new records of plant-parasitic nematodes in Korea. Highest maximum densities were showed by T. claytoni, Paratylenchus nanus, M. nebraskense, M. graminicola, and H. microlobus. Diversity (H'), was significantly higher in fairways compared to tees and greens, though species evenness (J') and dominance (D) showed no statistically significant differences. This information is crucial in nematode problem diagnosis, and the subsequent formulation of management strategies.
植物寄生线虫不仅是农作物生产的重要限制因素,还会对作为地被植物的草坪草造成直接和间接损害。然而,韩国关于草坪草植物寄生线虫的研究很少。对韩国13个高尔夫球场进行了植物寄生线虫调查。结果发现了属于12个科16个属的28种/类群的植物寄生线虫。在分离出的物种中,微小螺旋线虫、内布拉斯加中环线虫、克莱顿针线虫、中环线虫属和禾本科根结线虫是所有管理区域中最常见的物种。有12个物种是韩国植物寄生线虫的新记录。克莱顿针线虫、矮小拟盘旋线虫、内布拉斯加中环线虫、禾本科根结线虫和微小螺旋线虫的最高最大密度。多样性(H')在球道中显著高于发球区和果岭,尽管物种均匀度(J')和优势度(D)没有统计学上的显著差异。这些信息对于线虫问题诊断以及后续管理策略的制定至关重要。
