摘　　要：通过不同条件对玉米丝黑穗病菌冬孢子萌发率影响的试验研究表明,甲醛处理对玉米丝黑穗病菌冬孢子萌发有明显促进作用,萌发率达88.89%,冬孢子在麦芽糖和水琼脂培养基上萌发率最高达84.49%。在不同温度和pH条件下冬孢子萌发率差异较大。冬孢子在28℃时最适合萌发,达89.67%,在pH为7时萌发率最高达89.02%。Germination rate of teliospore of maize head smut were tested under different conditions. Results showed that germination rate of teliospore treated by formaldehyde was 88.89%, the highest germination rate of teliospore cultured in the maltose culture reached 84.49%; germination rates under different temperature and PH were very different, it was 89.67% at 28 ℃ (optimum temperature), 89.02% when PH was 7(optimum PH).
