Abstract

Bonsai is part of export forest products in Korea. Demand for bonsai exports to other countries is growing but the need for quarantine hazards must be eliminated in other to export. Plant parasitic nematode is also an important factor in quarantine. The nematodes were surveyed from bonsai farms in 6 areas of Korea. The surveyed deciduous bonsai plants were Acer palmatum, Zinnia elegans, Ligustrum obtusiflium, Carpinus turcaninowii, and Malus sieboldii. Three plant parasitic nematodes (Hemicyliophora koreana, Rotylenchus blothrotylus and Xiphinema americanum) and three non-parasitic nematodes (Aporclaimellus donghwaens, Egtitus andhricus, and Mesodorylaimus usitatus) were isolated from bonsai. Non-parasitic nematode, Mesodorylaimus usitatus was isolated from all surveyed bonsai trees. Only two species of quarantine nematodes (Hemcylicopora koreana and Xiphinema americanum) were found from bonsai. A. donghwaens and M. usitatus were isolated from root of bonsai tree. However other nematodes were isolated from soil in bonsai trees.

분재는 우리나라의 주요 수출 임산물이다. 외국으로의 분재수출 요구도는 증가하고 있지만 수출을 위해서는 검역적 위해 요소가 제거 되어야 하는데 식물기생선충도 검역의 중요 대상이다. 우리나라 6개 분재원에서 활엽수 분재[단풍나무(Acer palmatum), 백일홍(Zinnia elegans), 쥐똥나무(Ligustrum obtusiflium), 소사나무(Carpinus turcaninowii), 애기사과(Malus sieboldii)]를 대상으로 발생하는 선충을 조사하였다. 세 종의 식물기생선충[미국검선충(Xiphinema americanum), 둥근꼬리붙이나선선충(Rotylenchus blothrotylus), 한국껍질선충(Hemicycliophora koreana)]과 세 종의 비기생 선충 [등화육각창선충(Aporclaimellus donghwaens), 둥근꼬리붙이나선선충(Egtitus andhricus), 계룡중간창선충(Mesodorylaimus usitatus)]들이 분재로부터 분리되었다. 비기생선충인 계룡중간창선충은 모든 조사 수종에서 검출되었고, 미국 과 EU연합 검역대상 선충으로는 한국껍질선충과 미국검선충의 두 종만 발견되었다. 등화육각창선충과 계룡중간창선충은 분재목 뿌리에서 분리되었고, 나머지 선충들은 토양에서 분리되었다.
