在辽宁丹东新发现一种软枣猕猴桃根腐病害,罹病植株叶片枯萎,老叶变干凋谢,最后干枯死亡。通过组织分离法和单孢分离法获得纯化菌株HMQAU150043和HMQAU150044。经形态学观察、ef‐1a序列分析、mt SSU序列分析及柯赫氏法则验证,确定两株病原菌均为多见镰孢Fusarium commune。这是该菌所致软枣猕猴桃根腐病的首次发现。 In Dandong, Liaoning Province, a new species of jujube kiwifruit root rot was found. The leaves of diseased plants withered, the old leaves became dry and withered, and finally died of dryness. The purified strains HMQAU150043 and HMQAU150044 were obtained by tissue isolation and single spore isolation. Morphological observation, ef-1a sequence analysis, mt SSU sequence analysis and Koch’s rule validation, to determine the two pathogens are more common Fusarium commune. This is the first discovery of jujube kiwifruit root rot caused by the bacteria.
