Frequency of Powdery Mildew Resistances in Spring Barley Cultivars in Czech Variety Trials
Blumeria graminis f.sp. hordei Hordeum vulgare
2015/3/9
In 2006–2010, resistance to the powdery mildew pathogen was studied in 277 spring barley cultivars. They were
represented by 54 cultivars in Czech official variety trials, of which 42 were foreign, ...

Blumeria graminis f.sp. hordei Hordeum vulgare pathogen isolates resistance gene postulation
2014/2/25
A large number of resistances to powdery mildew (Blumeria graminis f.sp. hordei) and their combinations are known in barley (Hordeum vulgare L.). A similarity of resistance spectra between cultivars c...
Conductance of Tomonaga-Luttinger liquid wires and junctions with resistances
Tomonaga-Luttinger liquid wires junctions with resistances
2010/11/25
We study the effect that resistive regions have on the conductance of a quantum wire with interacting electrons which is connected to Fermi liquid leads. Using the bosonization formalism and a Rayleig...

2014/3/11
Virulence frequencies to powdery mildew resistances in winter barley cultivars mostly registered in
the Czech Republic were studied in 2007 and 2008. Random samples of the air populations originatin...
建立了芯铧式开沟器和播种施肥开沟器与土壤颗粒的二维离散元法分析模型，采用离散元法研究开沟器的工作过程及工作阻力，通过改变开沟器的CAD模型和土壤颗粒参数，分析不同条件下开沟器的工作阻力。在室内土槽进行了2种开沟器的工作阻力测试，并将测试结果与开沟器工作阻力的离散元法计算结果进行了比较，两者的变化趋势基本一致，相对误差在10%～20%之间，由此初步证明了采用离散元法分析开沟器工作过程和工作阻力的可行...
