摘要
通过病原菌致病性测定和形态鉴定，确认一品红枯萎病是由尖孢镰刀菌（ＦｕｓａｒｉｕｍｏｘｙｓｐｏｒｕｍＳｃｈｌ．）引起。采用浸根接种法和灌根接种法进一步对该菌进行寄主范围测定试验，被接种的１１个科１４种植物中仅有一品红发病，故鉴定该菌为一独立的专化型———尖孢镰刀菌一品红专化型（ＦｕｓａｒｉｕｍｏｘｙｓｐｏｒｕｍＳｃｈｌ．ｆ．ｓｐ．ｅｕｐｈｏｒｂｉａｅＺ．Ｄ．ＪｉａｎｇｅｔＰ．Ｋ．Ｃｈｉ，ｆ．ｓｐ．ｎｏｖ．）。
The pathogen of wilt disease of poinsettia was identified as Fusarium oxysporum schl. f. sp. euphorbiae Z. D. Jiang et P. K. Chi. f. sp. nov. according to its morphology, cultural character and pathogenicity. This pathogen only attacked poisettia among 14 species of plants on 11 families by the methods of impregnated inoculation and irrigated inoculation. The disease could cause basal stem rotted in the late stage.
