锈菌

In the past decades, DNA molecular markers have been applied to investigate the population genetics of wheat stripe rust fungus, and rapid progress has brought out in the research of P.

小麦条锈病是危害最严重的小麦流行性病害之一，小麦条锈菌的生态学研究对制定合理的防治策略和抗锈育种具有重要意义。

The volunteer wheat is also responsible forcarrying the leaf rust over summer for the winter wheat infection.

因此旅大区有时虽然有秆锈菌的越冬，但不可能是小麦秆锈越冬的主要场所。4。

Additionally the spatial pattern of wheat stripe rust at large scale was analyzed using the same methods.

明确了我国适合小麦条锈病菌越夏、越冬的范围，为制定越夏区治理方案提供依据，也有利于指导对条锈菌越夏、越冬情况的进一步调查。

Random primers was used to screen main dominance fungus strain of Chiese Melampsora larici-populina Kleb by RAPD technique and the special RAPD fragments of physiological laces of C1, C3, C4 and C5 were founded successfully.

以156条随机引物，对目前中国落叶松杨栅锈菌(Melampsora larici-populina Kleb)的主要优势菌系进行了BAPD片段的筛选，寻找到了1号、3号、4号、5号4个流行生理小种的特异性RAPD标记。

The study clarified the molecular genetic relations of major races and epidemic strains of Puccinia striiformis f.

明确近年来我国小麦条锈菌主要小种及流行菌系的分子遗传关系。

TcLr9,TcLrl9,TcLr38 and TcLr45 are resistant to Puccinia triticina race No.

本研究以编号05-21-116③的小麦叶锈菌为接种菌株，其致病类型为THTS。

Call grape layer rubiginous bacterium, belong to bacterium of a carring pole inferior door fungus.

病原 称葡萄层锈菌，属担子菌亚门真菌。

Category used in some systems to comprise the two orders Ustilaginales and Uredinales.

在某些系统中使用的一个分类范畴，由黑粉菌目和锈菌目组成。

More than 20 taxa of airborne fungi have been collected,among which the most common fungi were Uredinales,Ustilaginales,Alternaria,etc.Fungi spores were ralated with the season and weather,the most aboudant period in sring and summer.

结果：全年均可见真菌孢子，共收集真菌种类20多种，其中最常见的有链格孢、锈菌、黑粉菌等，其数量和季节、气候有关，以春季、夏季最多，秋季和冬季依次降低。

Ug99 could be called a superior virulent race to widely-used and Sr31-carrying Chinese wheat cultivars or stem rust resistant sources.The number of virulent genes contained in Ug99 was more than the total carried in all Chinese stem rust races.For instance,the virulence of Sr5,Sr9e or Sr11 was the typical races.However,besides the virulence of Sr5,Sr9e and Sr11,Ug99 contains additional virulence of Sr21,Sr31and Sr38,which have never been found in Chinese stem rust races.

Ug99堪称我国的超毒小种，我国最典型的秆锈菌小种只能分别克服或Sr5或Sr9 e或Sr11单基因抗性，而Ug99不仅具有Sr5、Sr9 e、Sr11的联合毒力，而且还具有Sr21、Sr31、Sr38的联合毒力，而我国从未有小种能克服后者的抗性。1B/1L(含Sr31)易位系曾是我国使用的重要秆锈抗源，必对Ug99高度脆弱，我国118份小麦品种在KARI的测定结果表明，高感品种频率98.3%。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
