The results showed that the disease incidence of maize head smut was 31.3% when the soil temperature was 24℃.

试验结果表明，土壤温度为21℃，玉米丝黑穗的发病率最高为31.3%，17℃低温下发病率为10.9%~16.7%，温度在24℃时，发病率为3.7%~4.8%；土壤含水量与病害侵染发病有较明显的关系，土壤湿度为15%时利于孢子萌发与侵染，发病率达为31.1%，湿度10%、20%时发病率仅为3.7%~8.8%，干旱和高湿不利于病菌孢子萌发，湿度是决定发病程度的主导因素。

Using logistic model, regression equations were established as followed: y=12.084 8/［1+exp (6.372 5-0.367 5x)］ and y=91.017 0/［1+exp （18.448 8-0.788 8x）］, which was used to evaluate the responses of maize inbred lines to head smut resistance.

采用逻辑斯蒂模型分别建立了抗、感自交系可溶性糖含量与田间发病率的一元曲线回归方程：y=12.084 8/［1+exp (6.372 5-0.367 5x)］和y=91.017 0/［1+exp（18.448 8-0.788 8x）］，以此建立了以接菌幼苗可溶性糖含量为指标的抗性评价方法，并用于未知抗性种质资源的鉴定。
