| 内容記述 | The infectivity tests were repeated and the average results obtained indicated that more than 1×10^4 oospores per gram oven dry soil (OPG) caused damping-off of 80% of Chenopodium quinoa seedlings. About 20% damping-off occurred with 1×10^3 OPG. With 1×10^2 OPG the average was 6%, and penetrating mycelium and oospores were easily recognized. Neither penetration nor disease incidence was found with 1×10 OPG. Thus, the minimum number of oospores capable of inducing disease was estimated to be 10-1×10^3/g oven dry soil. The fact that P.zingiberum needs much more oospores than P.butleri to induce disease may be connected with lower germinability of oospores of the former. | |||||
