摘要: 从患病的亚麻根部获得分离物,经鉴定及致病性测定,经过完整的柯赫证病过程证实,引起亚麻萎蔫病的致病菌主要是尖镰孢菌,发病率达61%,其次为立枯丝核菌,发病率达21.2%,拟枝孢镰孢菌,发病率达17.8%.

关键词: 亚麻, 萎蔫病, 病原菌

Abstract: The isolation fungi obtained from diseased flax roots were identified and pathogenicity testedThe result showed that flax flaccid disease was caused by Fusarium oxysporum, Rhizoctonia solani and Fusarium sporotrichioides,their disease incidences were 61% ,21.2% and 17.8%,respectively.
