摘要
经对秦岭主峰太白山自然保护区的乔灌木病原真菌区系进行分析,结果表明,该地区真菌种类资源丰富,共鉴定出66属216种病原真菌,其中16种为中国新记录,陕西新记录52种。锈菌区系以温带属为主,亚热带、热带属并存,地理成分体现中国——日本和中国——喜马拉雅森林植物锈菌区系的特征。病害随森林植被垂直分布带的变化而形成不同的分布格局。
Describes 66 genera and 216 species of pathogenic fungi found and identified on forest trees and shrubs in Taibai Natural Protected Area. Among these, 16 species were newly recorded in China, and 52 species were newly recorded in Shaanxi Province. In rust flora, the temperate genera were dominated and coexisted with the subtropical and tropical genera. The geographic compo-nentsof rust flora reflected the Stno-Japanese and Sino-Himalaya features. The forest diseases formed different distribution patterns in accordance with the vertical distribution of forest vegetation.
