查询词典 kernel smut

Rice false smut caused by Ustilaginodea virens Tak is a worldwidefungal disease in rice, which its occurrence and damage globally tends to more andmore serious. The disease is not only greatly decrease the yield and quality of rice, butits ustiloxins may also cause poisoning to human and animals.

水稻稻曲病是由稻曲病菌引起的水稻穗部真菌性病害，该病害在世界产稻区都有发生，目前该病危害呈加重趋势，不仅影响水稻产量和品质，而且产生的稻曲病菌毒素对人和动植物都有毒性。

Based on above classification, resistant scale of the rice cultivars against false smut asthe field evaluation may be divided into 6 scales, viz. 0: 0.00～0.09disease grains ofthe average each panicle; 1: 0.01～0.30; 3:0.31～0.40; 5: 0.41～0.50;7:0.51～1.10; 9:＞1.10.

以以上分类为依据，将水稻抗稻曲病的田间抗性相应地划分为6级：0级：平均每穗病粒数为0.00～0.09；1级：平均每穗病粒数0.10～0.30；3级：平均每穗病粒数0.31～0.40；5级：平均每穗病粒数0.41-0.5；7级：平均每穗病粒数0.51～1.10；9级：平均每穗病粒数＞1.10。

False smut is a worldwide rice disease caused by Ustilaginodea virens Tak.

稻曲病是世界性水稻真菌病害，致病菌属于子囊菌纲球壳菌目麦角菌科绿核菌属Ustilaginodea virens

The most convenient and effective method among the three methods of isolatingUstilaginodea virens was the vibrating method. XBZ medium was the best method toget chlamydospores through screening for the six media. Based on chlamydosporesthrough vibrating cultured in PS liquid on shaking bed at 130r/min under 26℃darkconditions for 7 days, conidia were largely obtained. Occurrence information of rice false smut on paddy at Hengnan in 2006 wasinvestigated.

稻曲病病原菌用3种方法分离，结果比较得出振落法最方便有效；通过对6种培养基的比较筛选，结果表明胁本哲氏培养基能快速的产生大量的厚垣孢子；把厚垣孢子放在PS培养液于水平摇床上26℃黑暗条件下130r／min振荡培养，能在7d产生大量分生孢子。

ConclusionComprehensive consideration suggested that jiarun15ml/hm2、15%xiugu caneffectively control sheath blight and false smut of rice,and commodity features of rice was improved,can substictute difenconazole.

结论经综合考虑，嘉润0.3g/ml乳油15ml/hm2、15%秀谷可湿性粉剂40g/hm2可有效防治水稻纹枯病和稻曲病，有利于提高稻谷的商品性能，可替代30%爱苗乳油。

The study aimed to research the molecular marker of head smut gene of sweet sorghum by RAPD technology.

［目的］应用RAPD技术对甜高粱丝黑穗病基因进行分子标记研究。

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 resistances to head smut of some CIMMYT maize populations were identified by the method of artificial inoculation under field condition to direct the introduction and utilization of CIMMYT maize germplasm in China.

本文采用田间人工接种方法研究了部分CIMMYT玉米种质及其测交组合对丝黑穗病的抗性，为CIMMYT种质的引进和利用提供参考。
