Notes:
When sclerotia of a Canadian isolate of Sclerotinia sclerotiorum were exposed to temperatures of – 10 or– 20 C for 4 weeks, their germination behaviour changed from carpogenic to myceliogenic type. Mycelial growth from sclerotia exposed to– 20 C was more vigorous than that from sclerotia exposed to– 10 C. The mode of germination in sclerotia treated with above-freezing temperatures of 0 5, 10. 15. 25 or 30 C did not change: they retained the capacity for carpogenic germination. The possible epidemiological impact of this low-temperature induction of myceliogenic germination on the development of sclerotinia wilt of sunflower seedlings in western Canada is discussed.
