摘要
A comparison of the ability of ten known mycoparasites to infect sclerotia of Sclerotinia sclerotiorum was made using five combinations of inoculum form and substrate type. Inoculum forms consisted of spore suspensions prepared in distilled water or 1% peptone water and a maizemeal-perlite solid substrate formulation. Substrate types consisted of acid-washed sterile sand or non-sterile soil. In every combination, Gliocladium virens and Coniothyrium minitans, both originally isolated from sclerotia of Sclerotinia species, infected and decreased viability of sclerotia more frequently than the other mycoparasites tested. Inoculum form of these two mycoparasites and substrate type had significant effects on the degree of sclerotial infection and viability. The ability to sporulate on the surface of inoculated sclerotia is not considered a useful method of assessing mycoparasitism. The relevance of these results to the choice of screening system for mycoparasites of sclerotia of S. sclerotiorum is discussed. © 1990, British Mycological Society. All rights reserved.
