六十年代末期以来,新疆各地小麦腥黑穗病为害均普遍回升,严重的发病率可达60—80％,给小麦生产造成较大的损害。新疆小麦腥黑穗病的菌原光腥黑穗病菌(Tilletia foefida)和网腥黑穗病菌(Tillefia caries)都有,仅是因地区而异,惟据了解,似以网腥黑穗病菌的分布和为害占优势。1981年,我们将采自南,北疆一些地区的小麦网腥黑穗病标本,经过比较鉴定,发现南、北疆的病原冬孢子无论从形态学或是生物学方面都存在差异。联
Since the late 1960s, the prevalence of wheat-related smut in various parts of Xinjiang has generally risen, with a serious incidence of 60-80%, causing great damage to wheat production. Tilletia foefida and Tillefia caries are all present in Xinjiang wheat smut only because they differ only by region. However, Distribution and damage dominant. In 1981, we collected samples of wheat nematode from wheat and some areas in northern and northern Xinjiang. After comparative identification, we found that there are differences in morphological or biological aspects between southern and northern Xinjiang. United
