麦角菌是由紫锁头菌引起的，是小麦的一种有害病原体，因为这种真菌的菌核对动物和人类都是有毒的。本研究的目的是确定目前注册的加拿大小麦品种和试验小麦品系对紫茎枯病的反应是否存在差异，并确定不同类别的小麦[加拿大西部红春（CWRS）、加拿大草原春（CPS）、加拿大西部特强（CWES）、加拿大西部软白春（CWSWS）和加拿大西部琥珀硬粒（CWAD）]的抗性水平是否存在差异。将来自加拿大西部不同小麦类别的54种小麦基因型与6株紫孢杆菌的混合物接种，并评估每穗产生的菌核数量、产生的菌核大小和产生的蜜露量。总体而言，CWAD小麦每穗菌核数显著减少，cwws小麦每穗菌核数显著减少。这些班级在……方面没有什么不同。
Ergot, caused by Claviceps purpurea, can be a detrimental pathogen of wheat because the sclerotia of this fungus are toxic to animals and humans. The purpose of this work was to determine if currently registered Canadian wheat cultivars and experimental wheat lines differ in their reactions to C. purpurea and to determine if different classes of wheat [Canadian Western Red Spring (CWRS), Canadian Prairie Spring (CPS), Canadian Western Extra Strong (CWES), Canadian Western Soft White Spring (CWSWS), and Canadian Western Amber Durum (CWAD)] differ in their levels of resistance. Fifty-four wheat genotypes from different western Canadian classes of wheat were inoculated with a mixture of six isolates of C. purpurea and assessed for the number of sclerotia produced per spike and rated for sclerotial size produced and the amount of honeydew produced. In general, CWAD wheats produced significantly fewer sclerotia per spike and the CWSWS wheats had significantly smaller sclerotia. None of the classes differed in ...
