| 摘 要： | 从我国新疆、内蒙、西藏、北京和山东等省区的小麦、大麦、野黑麦、冰草、偃麦草和雀麦上分离到13个黑颖病菌株,在苗期、分蘖期和孕穗期,喷雾接种16属27种禾本科植物,对其中感病的6属15种植物和燕麦又做注射接种。根据各个菌株对小麦、大麦、黑麦、冰草、偃麦草和雀麦的致病性差异,初步将其划分三个致病变种:1.禾谷类致病变种X.campestris pv.cerealis (Hagborg) Dye.]:包括7个菌株,自然条件下发生在冰草、雀麦和偃麦草上;人工接种还可侵染小麦、大麦和黑麦。2.小麦致病变种(X.campestris pv.undulosa):包括4个菌株,自然条件下发生在小麦上,人工接种可侵染大麦和黑麦,但有一个菌株注射接种能轻度侵染雀麦。3.大麦致病变种(X.campestris pv.hordei):包括2个菌株,自然条件下发生在大麦上,注射接种能轻度侵染偃麦草。13个菌株喷雾接种猫尾草、早熟禾、画眉草、马唐、狗尾草、稗草、披碱草、羊茅草和水稻、均不侵染。

| Abstract: | Thirteen strains of Xanthomonas campestris were isolated from wheat, barley and some cereal grasses in Xinjiang, Mongonlia, Tibet, Beijing and Shan-dong. 27 kinds of the grass family belonging to 16 genuses were inoculated with spray method at seedling, tillering and boot stage respectively. The results showed that the pathogen could infect 15 species of plants belonging to 7 genera. According to the difference in pathogenicity on wheat, barley and rye, we could classify 13 strains into 3 pathovars namely:1) X. campestris pv. erealis which naturely infected Agropyron spp., Bromus spp. and Elyirigia spp. as well as artificially infected wheat, barley and rye. 2) X. campesiris pv. undulosa which naturely infected wheat whill infected barley and rye by inoculation. 3) X. campestris pv. hordei naturely infected harley and weakly infected Agropyron spp. and Bromas spp. by leaf innoculation. |
