查询词典 maize smut

Maize head smut brings great waste on production in Jilin province and it has become more and more serious for recent years.

吉林省近几年玉米丝黑穗病有逐年加重的趋势，给粮食生产带来巨大的损失。

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。

The resistance mechanism of maize to head smut were first studied by determining endogenous hormone changes during host - pathogen interaction.

本文从寄主与病菌互作过程中植物内源激素变化揭示玉米对丝黑穗病的抗性机制。

The study indicated continous corpping for years, planted inresist disease varieties, unusual climate, lacking of scientific methed of prevention and cure, returning maize straw to infield are major factors to creat head smut.

研究表明，玉米连年重茬，种植感病品种，气候变化异常，缺乏科学的防治措施及部分地区推广的秸秆还田是诱发丝黑穗病发生的重要因素。

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。

Resistance: high resistance to falling over, the northern Blight of corn, the grey leaf spot of corn head smut and maize Borer.

抗性：高抗倒伏、玉米大斑病、玉米灰斑病、玉米丝黑穗病、玉米螟。
