초록

국내 과채류 재배단지의 뿌리혹선충 발생에 관한 조사를 위해 1997년부터 1999년까지 경북 성주군을 중심으로 경기 여주군, 경남 함안군, 충북 청원군 등에서 과채류재배지의 토양을 채집하여 식물기생선충 종류와 밀도 조사, 뿌리혹선충 암컷의 효소표현형에 의한 종 동정을 실시하였다. 경북 성주군의 185개 참외재배 포장 중 99개 포장(53.5%)에서 뿌리혹선충이 검출되었고 나선선충류(Helocotylenchus spp.)는 7개, 둥근꼬리선충류(Aphelechus spp.)는 43개, 환선충류(Criconematid)는 26개 포장에서 검출되었다. 뿌리혹선충 암컷의 Malate dehydrogenase 및 Esterase 등 2가지 효소표현형을 이용하여 한국에 분포하는 주요 4종의 동정이 가능하였다. 효소 표현형을 이용하여 성주군 선남면에서 채집된 13개 시료 중 당콩뿌리혹선충으로 동정된 것이 6포장, 고구마뿌리혹선충 5포장이었으며 2개 포장은 두 종의 혼재하는 것으로 나타났다. 성주군 초전면의 6개 포장 시료 중 4개가 땅콩뿌리혹선충, 1개가 고구마뿌리혹선충으로 동정되었으며 1포장의 뿌리혹선충은 효소표현형이 미동정 종으로 나타났다. 경기도 여주군의 참외재배단지에서는 14개 조사대상 중 당근뿌리혹선충이 11개 포장, 땅콩뿌리혹선충이 3개포장으로 당근뿌리혹선충이 우점종인 것으로 나타났다.

This study was conducted to analyse the distribution of root-knot nematodes (Meloidogyne spp.) in fruit vegetable production areas in Korea. Soil samples were collected from greenhouses in Sungju (Kyungpook), Yeoju (Kyungki), Haman (Kyungnam), and Chungwon (Choongpook) provinces in 1997-1999. Plant parasitic nematodes were separated for density counting and some of the root-knot nematodes were identified using enzyme phenotypes of malate dehydrogenase (MDH) and esterase (EST). Among the 185 farms in Sungju province, Meloiciogyne spp. were detected from 99 farms (53.5%). Other plant parasitic nematodes detected were; Helic~otylmchuss pp. from 7 farms, Aphelenchus spp. from 43 farms, and Criconematids from 26 farms. Using the female enzyme phenotypes of MDH and EST. the four major root-knot nematodes in Korea, M. incognitc~(M I), M. uretznri~(M~ A), M. huplu (MH), and M. juvunica, could be identified. In the enzyme phenotype identification of 13 populations collected from Sunnam in Sungju province, 6 populations were identified as MA, 5 populations were identified as MI, and 2 populations were mixed with MI and MA. Among the 6 populations from Chojun in Sungju province. 4 populations were MA, one population was MI, and one population showed enzyme phenotypes of unknown species. Among the 14 populations of Yeoju province, l I populations were MH and 3 populations were MA.
