- W2895859820 abstract "＇97∼＇98년에 경북지역의 대구와 경산, 군위, 영천, 청도등 대추과원에서 과실에 역병이 발생되었다. 병징은 과실이 적갈색의 반점이 생기며 심하면 미이라가 되고, 말라서 조기낙과되며 엽병과 신초에도 마름증상을 나타내기도 했다. 이병과에서 2종의 역병균이 검출되었는데 총 18개 역병균중 6균주는 P. nicotiamae로 동정되었고, 나머지 12균주는 P. palmivora로 동정되었다. P. nicotianae는 유두돌기가 뚜렷하고 비탈락성인 구형 혹은 난형의 유주자낭과 다량의 후막포자를 형성하였으며 유성생식형은 자웅이주로 A1 mating type이 조사되었다. P. palmivora는 유주자낭이 유두돌기가 뚜렷하고 탈락성이며 장타원형 혹은 난형, 구형 등이었고, 다량의 후막포자를 형성하였으며 유성생식형은 자웅이주로 A1 mating type이 조사되었다. 2종의 역병균 모두 대추와 배에 강한 병원성을 나타내었으나. 사과에는 병원성이 없었다. P. nicotiamae 와 P. palmivora에 의한 대추 역병은 국내에서 최초로 보고되는 것이다. Two species of Phytophthora were isolated from infected fruits of jujube. Among 18 isolates collected, 6 were identified as P. nicotianae and 12 as P. patmivora on the basis of their mycological characteristics. The former produced no caduceus, ovoid to spherical sporangia in contrast to caduceus, ellipsoid, and broadly avoid to spherical ones of the latter. These two species were shown to be heterothallic and markedly papilate, chlamydospores abundant, and Al mating type. They skewed strong pathogenicity to fruits of jujube and pear while no symptom was produced on apple fruit by artificial inoculation. This is the first report of juiube fruit rot caused by P. ninotianae and P. palmivora in Korea." @default.
