| 摘 要： | 【目的】研究壳囊孢属真菌(Cytospora spp.)的种类及在新疆的分布特征。【方法】在新疆14个地(州)共收集到2 763份病害标本,鉴定出27种壳囊孢属真菌,采集文献资料记载新疆累计记录51种壳囊孢属真菌,采用ArcGIS软件、Gephi软件及Spreensen公式不同种类壳囊孢属真菌在新疆不同地区和寄主上的分布情况及相似性。【结果】壳囊孢属真菌在新疆伊犁地区(31种)、乌鲁木齐市(27种)、塔城地区(21种)和昌吉地区(20种)分布壳囊孢种类及数量较多;在克孜勒苏柯尔克孜自治州(3种)、巴音郭楞蒙古自治州(3种)和和田地区(2种)分布较少;该菌能够寄生于21科植物中,其中蔷薇科(19种)、杨柳科(18种)、胡颓子科(8种)植物的种类及数量较多;桑科(1种)、忍冬科(1种)、无患子科(1种)等植物上较少。金黄壳囊孢菌(Cytospora chrysosperma)在全疆15个地州(市)的11科寄主均有分布;壳囊孢属真菌在海拔600~900 m处分布较为丰富,阿克苏和吐鲁番两地间的相似性系数最高。【结论】新疆现已记录51种壳囊孢属真菌,其中受金黄壳囊孢菌(C. chrysosperma)危害的植物种类最多,蔷薇科、杨柳科、胡颓子科植物上分布的壳囊孢属真菌种类较多。

| Abstract: | 【Objective】 To clarify the species of Cytospora and its distribution characteristics in Xinjiang Uygur Autonomous Region (Xinjiang). 【Methods】 The research team collected a total of 2,763 specimens of Cytospora canker disease in 14 prefectures in Xinjiang and 27 species of Cytospora were identified. Based on literature data, there were 51 species of Cytospora recorded in Xinjiang. The study obtained the distribution and similarity of different Cytospora in different regions and hosts in Xinjiang through ArcGIS software, Gephi software and Spreensen formula. 【Results】 The results showed that the diversities of Cytospora species in Xinjiang Yili (31 species), Urumqi (27 species), Tacheng (21 species) and Changji (20 species) were high; Those in Kezhou (3 species), Bazhou (3 species) and Hetian (2 species) were low. Cytospora spp. could parasitize 21 families host plant, including Rosaceae (19 species), Salicaceae (18 species), Elaeagnaceae (8 species), Moraceae (1 species), Caprifoliaceae (1 species), Sapindaceae (1 species) andothers. Cytospora chrysosperma was distributed in 12 families host plants in 15 areas (cities) of Xinjiang. Cytospora spp. was abundantly distributed at an altitude of 600-900 m. And the similarity coefficient between Aksu and Turpan was the highest. 【Conclusion】 Xinjiang has recorded 51 species of Cytospora, among which, C. chrysospermais is the most widely distributed species. Rosaceae, Salicaceae and Elaeagnus are the main host plants in Xinjiang. |
