Zusammenfassung: | The study was conducted to investigate the infestation and distribution of plant-parasitic nematodes on kiwi orchards in Korea. Plant parasitic nematodes genus and densities were investigated at a total of 102 sites in Jeollanam-do, Gyeongsangnam-do, and Jeju-do, which are the main production areas of domestic kiwi orchards. Plant parasitic nematodes detected were of 9 genera, including root-knot nematodes (Meloidogyne spp.), spiral nematodes (Helicotylenchus spp.), and needle nematodes (Paratylenchus spp.), and 56% of the 102 plantations were infected with root-knot nematodes. Root-knot nematodes were found to be the most important plant parasitic nematode in domestic kiwi orchards. The average density of root-knot nematodes is 97 per 300 cm3 soil, and there is concern about the kiwi yield reduction. As a result of identifying the root-knot nematode species: M. arenaria, M. hapla, M. incognita, and M. javanica. Among them, M. arenaria is the most dominant. As the plant parasitic nematode infection route in fruit trees is often spread through the transplantation of infected seedlings, attention should be paid to the production of nematode-free plants during the production and supply of kiwifruit plants. 국내 참다래 주산지인 전라남도, 경상남도, 제주도 지역의 참다래 재배지 총 102개 지점을 대상으로 식물기생선충 종류와 밀도를 조사하였다. 검출된 식물기생선충은 뿌리혹선충(Meloidogyne spp.), 나선선충(Helicotylenchus spp.), 침선충(Paratylenchus spp.) 등 9개의 속이었으며, 102개 재배지 중 56%의 재배지가 뿌리혹선충에 감염되어 있는 것으로 나타나 국내 참다래 재배지에서 가장 중요한 식물기생선충은 뿌리혹선충이었다. 뿌리혹선충의 평균 밀도는 97마리/300 cm3 토양으로 참다래의 수량 감소 피해가 우려된다. 뿌리혹선충의 종을 동정한 결과, M. arenaria, M. hapla, M. incognita, M. javanica 4종이 확인되었으며, 그 중 M. arenaria가 가장 우점하고 있다. 그 중 M. arenaria가 가장 우점하고 있다. 과수류에서의 식물기생선충 감염 경로는 감염된 묘목의 이식을 통한 확산이 많음으로 참다래 묘목 생산 및 보급단계에서 뿌리혹선충 무균묘 생산에 주의를 기울여야 할 것이다. |
