| 摘 要： | During an investigation of mycoparasitic fungi on sclerotia of Sclerotinia sclerotiorum in China, Gliocladium species was consistently encountered and isolated from natural soils collected over the country. Colonization frequencies on sclerotia of S. sclerotiorum by the fungi ranged from 40% to 100% when the sclerotia were introduced into soils and coincubated at 22-24 ℃ for 4 weeks. Identification showed that G. roseum, G. virens and G. catenulatum were the dominant species amon…

| Abstract: | During an investigation of mycoparasitic fungi on sclerotia of Sclerotinia sclerotiorum in China,Gliocladium species was consistently encountered and isolated from natural soils collected over the country. Colonization frequencies on sclerotia of S. sclerotiorum by the fungi ranged from 40% to 100% when the sclerotia were introduced into soils and coincubated at 22-24 ℃ for 4 weeks.Identification showed that G. roseum, G. virens and G. catenulatum were the dominant species among the 300 isolates gained. Molecular taxonomy of some Gliocladium isolates analysed by rDNA ITS sequence used ITS1 and ITS4 as primers was demonstrated to be identical with morphological classification. |
