| 内容記述 | Two soil-borne fungi, P. paddicum and P. iwayamai, causing Pythium snow rot of wheat and barley, were compared for the behaviour of oospores under various cultural conditions. On Bacto-cornmeal agar (CMA) medium, optimum temperatures for oospore germination were approximately 20℃ for P. paddicum and 10-25℃ for P. iwayamai. On CMA adjusted to pH values between 4.8 and 8.2 with a MES [2-(N-morpholino) ethanesulfonic acid] buffer, both fungi germinated well. P. paddicum reached the best germination at pH 5.5, P. iwayamai at 6.5. On CMA amended with a non-ionic mannitol to adjust osmotic potential between -1.3 and -37.2 bars, oospores of P. paddicum were able to germinate only above -10.2 bars, but those of P. iwayamai germinated above -19.0 bars, with the highest germination rate between -3.4 and -19.0 bars. The relationship between the results obtained and the ecology of the two fungi is discussed. | |||||
