新疆灌木锈菌的分类鉴定

TAXONOMIC STUDY OF RUST FUNGI ON SHRUBS IN XINJIANG

通过光学显微镜和扫描电子显微镜对采自新疆荒漠植被的62份灌木锈菌标本进行分类鉴定。共鉴定出灌木锈菌17个种,其中Phragmidium有10个种,Uromyces 5个种,Puccinia 2个种,Phragmidium,andersonnii Sheat和Puccina longirostris Kom为中国新纪录种。

Seventeen species of rust fungi on shrubs in Xinjiang are reporeed in this paper. These species belong to three genera Phragmidium, Puccinia, Uromyces among with 2 species are new records in China: phragrnidiurn andersomii Sheat ; Puccinia Longirotris Kom. The author examined and differentiated 62 spcimens of rust on shrubs collected throught Xinjiang, most speciemen collected from Gobi Desert where the rust flora is still imperfectly known. After morphological studies under microscope and scanning electromicroscope by observing Undiospore, tetispore and in somecase with Spemogone and aecidium. The classification is discussed. The characteristcs of each species, host range and geographical distribution are described every species have photograph of scanning electron microscopy. All the specimens cited above are deprited in the Mophylogical Herbarium of Xinjiang August First Agricultural College (HMAAC)
