【摘要】 本论文对内蒙古杨柳科植物上的栅锈菌进行了系统的分类研究。鉴定标本共286号。这些标本来源于早年本校师生自内蒙古各地的采集和本人2003年至2005年间随同导师及其课题组成员到内蒙古各地区的采集。寄主植物涉及杨柳科3个属:杨属15个种、柳属23个种、钻天柳属1个种。共得到栅锈菌种19个:寄生于杨属的4个种、柳属的14个种和钻天柳属的1个种。其中国内新记录种共7个,包括柳属上6个:Melampsora euonymi-capraearum Kleb. ex Kleb.、M. kupreviczii Zenk.、M. lapponum Lindf.、M. larici-pentandrea Kleb.、M. repentis Plowr.和M. ribesii-viminalis Kleb. ;钻天柳属上1个:M. Kamikotica S. Kaneko & Hirats. f.。内蒙古新记录种10个,除上述7个,另外3个为:M. ribesii-purpureae Kleb.、M. salicis-albae Kleb.和M. tsinlingensis Z. M. Cao et J. Y. Zhuang。本文对这19个种编列了检索表,对每一个种均附有同物异名的订正、形态描述、显微照片及分析讨论。并对杨柳科植物上栅锈菌分类性状、观察方法以及Melampsora属中种的概念等进行了初步讨论。更多还原

【Abstract】 A systemetic taxonomic study was carried out on Melampsora on the Salicaceae plants in Inner Mongolia in the paper. Identified specimens were all together 286 pieces. These specimens rooted in the collections of our university’teachers and students to some regions of Inner Mongolia in the year one, and the collections of my tutor followed by his task group members and me to all regions of Inner Mongolia from the year of 2003 to 2005. The hostplants involved 3 genus of Salicaceae: 15 species of Populus, 23 species of Salix and 1 species of Chosenia. 19 species of Melampsora were obtained: 4 species parasitized on Populus, 14 species on Salix and 1 species on Chosenia. Thereinto 7 species are new record for China, including 6 species on Salix: Melampsora euonymi-capraearum Kleb. ex Kleb.、M. kupreviczii Zenk.、M. lapponum Lindf.、M. larici-pentandrea Kleb.、M. repentis Plowr. and M. ribesii-viminalis Kleb.; 1 species on Chosenia: M. Kamikotica S. Kaneko & Hirats. f.. 10 species are new records for Inner Mongolia, except for 7 species above, another 3 species are M. ribesii-purpureae Kleb.、M. salicis-albae Kleb. and M. tsinlingensis Z. M. Cao et J. Y. Zhuang. In this paper the 19 species were made into a searching list. To every species, there were their corrected synonyms, morphology descriptions, micrographs and analysis discussions. There were also primary discussions about Melampsora on the Salicaceae plants of taxonomic characters, observeing methods, species conception and so on.更多还原
